Detailed description of the invention:
One can at the drag reduction technology of high ferro, motor-car, rapid (below be collectively referred to as the high speed trains such as high ferro) exterior applications, it can, by the drag reduction overcoat (3) being arranged on headstock rectification centrum district outside face, become whirlpool drag reduction casing sheets fairing (15) jointly to form with the tool of all compartments outside face.Also can pass through at nearly all compartment outside face, all tool for mounting becomes whirlpool drag reduction casing sheets fairing (15) to carry out drag reduction.
Also can by the drag reduction overcoat (3) being arranged on headstock rectification centrum district outside face, from all compartments outside face and between different compartment connector outside, made Jian Jucheng whirlpool, compartment drag reduction casing sheets fairing is formed jointly.Equally also by nearly all compartment outside face, all tool for mounting becomes whirlpool drag reduction casing sheets fairing; Also between different compartment, connector is outside simultaneously, and intercropping tool in compartment processed becomes whirlpool drag reduction casing sheets fairing cooperatively to carry out drag reduction.
During the different modes fairing installed at compartment outside faces such as high ferro, motor-car, rapids in addition combines, afterbody drag reduction overcoat can be made in the rearmost part of last vehicle of train.
At the drag reduction overcoat that the high speed train forefront outside faces such as high ferro are installed, its most basic structure be by the drag reduction overcoat outer shell (3) moving gap (4) outside admission port (1), surperficial tool gas, ribbed support bar (5), drag reduction overcoat inside gas mobile space (8), inlet cone (12) be mainly to form.And within drag reduction overcoat admission port (1), preferably make, so that by free air diffuser (6) or inner side gas piping (23), after the gas entering admission port being transported to drag reduction overcoat postmedian or rear portion near sites, then make it later to travel forward along managing (7) gap in drag reduction overcoat outer shell (3) and air inlet.Reduce or eliminate the internal drag of gas when drag reduction overcoat medial motion.In the admission port (1) of this external drag reduction overcoat front portion or afterbody, also preferably should install and help air inlet component, to improve the drag reduction efficiency of drag reduction overcoat based on the gravitational attraction of gravitation fan (12).
Although the gravitation fan (12) installed in drag reduction overcoat admission port (1) is not the component part that must have in drag reduction coating device.But in the front portion of drag reduction overcoat or afterbody admission port (1) inner side, if similar Fig. 2-4,7,9,12-15, draw in 17 such gravitation fan (12) is installed, then because the amount of air being entered drag reduction jacket internal by admission port (1) can be increased considerably in pole, and make these enter extremely a large amount of high-speed motion air draughts of drag reduction overcoat, can move in gap (4) from the gas on drag reduction overcoat (3) surface, continuous very fast outside overflow be spouting.So will inevitably because moving in gap (4) outside drag reduction sleeve surface gas, the extremely large quantity of air air-flow that continuous outwards high speed is erupted and gone out, the high speed trains such as relative high ferro can be blown on one's face just at a high speed and move and next air draught, constantly outwards carry out strong outer blowing property extruding, cause its sense of motion that strongly outer moving occurs, finally make it be almost completely can not with the forward outer surface of the high speed trains such as high ferro, directly contact with each other.So in drag reduction overcoat forefront admission port (1) at the high speed train head positions such as high ferro, as made gravitation fan (12) device, the anterior head position of the high speed trains such as high ferro can be made, than admission port (1) air inlet only adopting punching press air inlet, be more conducive to realizing the punching press windage that very big amplitude eliminates windward side.Even do not get rid of the windward side stampability windage that can therefore will also cannot eliminate completely now, final reduce more than 50-70% or more be all that tool is possible.
The simultaneously relatively air draught that blows against one's face of the high speed train head such as high ferro, after the drag reduction outer jacket surface by just moving the continuous outwards a large amount of high speed jet in gap (4) from gas, because air-flow can become the constantly strong rotating vortex state that headstock direction is pointed in inner side, nature its subsequently by moving movement backward to Rea car body perimeter (be actually Rea car body constantly forward high-speed motion to the region of the such eddy current of firm formation) after, the air-flow skimming over Rea car body outside can be made again, no longer constantly move from front to back, but eddy current type constantly skims over backward, the drag-reduction effect of Rea car body can be increased considerably in pole further so especially.
At the afterbody in the rearmost part compartment of the high speed trains such as high ferro, although also often by constantly being reduced by car body height, and formation rectification centrum district can be made.But at it in company with the continuous high speed motions forward of whole anterior railway car, at the rear area near rear portion, such afterbody compartment, still can the depression that significantly reduces of mineralization pressure, so to run at high speed motion process at trains such as high ferros, the existence of the very large negative pressure of intensity (infrabar that relative normal barometric pressure significantly reduces is actual is exactly negative pressure) that also can produce because of motion, forms very large vacuum suction resistance.Although fairing profile Tail Shape being made as reduced diameter can drag reduction, the possibility of result done like this is only by because of high-speed motion, and the vacuum suction resistance produced reduces a very fraction.But if draw in similar Fig. 7-8 such, at the outside face in rear portion rectification centrum district, afterbody compartment, afterbody drag reduction overcoat (3) device is installed, then because gap (4) can be moved outside the gas by drag reduction overcoat appearance, continuous a large amount of outside Overflow ejection air stream, offset outside negative pressure resistance, so resistance of motion will inevitably be made to occur to reduce by a larger margin.
In the anterior admission port (1) of high speed train forefront drag reductions overcoat (3) such as high ferro, when installing gravitation fan (12), its power needed for motion, preferably adopts rotative speed electrical motor and so on the driving engine (19) of greatly amplitude adjustment as required to provide.But also by between electrical motor and so on driving engine (19) and gravitation fan (12), making significantly can change the transmission system of kinematic velocity, improve drag reduction overcoat (3) working process to change with high speed train kinematic velocity, and change the rotative speed change of gravitation fan (12) working process, and in drag reduction overcoat, producible working gas quantity changes alerting ability.Final more than drag reduction 50-70% further or more there is very large possibility equally.
In the inner side of the anterior admission port (1) of the high speed train forefront drag reduction overcoats such as high ferro, preferably as Fig. 1-2 in possibility situation, that draws in 4-5 etc. is such, as far as possible all make the interior pipe of air inlet (7) or the inner side gas piping (23) of the certain length that extends back, so that will from the air draught of admission port (1), significantly deliver to middle part or the rear portion near sites of drag reduction overcoat afterwards, and then make it to move forward or backward in drag reduction overcoat, so just significantly can reduce air after entering drag reduction overcoat admission port (1), inside moving resistance when moving further, and therefore increase substantially the drag-reduction effect of drag reduction overcoat.
And in high speed last vehicle of train rectification centrum districts such as high ferros, during as installed afterbody drag reduction overcoat (3), then required to external eruption gas during afterbody drag reduction overcoat (3) work, that can draw in similar Fig. 7 is such, by the outer surface portions in high speed last vehicle of train drag reduction overcoat fronts such as high ferros, make the special admission port (1) that arrives several circular hole or rectangular apertures shape, and at the inside line of these special admission ports (1), install and drag reduction overcoat (3) surperficial admission port (1), or with drag reduction overcoat posterior medial admission port (1) interconnective inner side gas piping (23), and based on gravitation fan (12) by gravitational attraction additional-air inlet parts, come jointly for drag reduction overcoat provides gaseousness material required for working process.
In the afterbody rectification centrum district of the high speed trains such as high ferro, during as installed afterbody drag reduction overcoat (3), required to external eruption gas during its work, that also can draw in similar Fig. 8 is such, by at the whole of the fronts, high speed last vehicle of train rectification centrum district such as high ferro or nearly all annular outer surfaces, make the special admission port of flat open type (1) of a large loop shaped of tool, for drag reduction overcoat provides the material of the gaseousness required for working process.This quadrat method of certain employing also may increase some ram drags, but the vacuum suction resistance of the high speed last vehicle of train such as its high ferro that therefore can significantly reduce relatively, the scaling factor v increasing resistance like this should be very little.
Be arranged on gravitation fan (12) device in the anterior admission port (1) of drag reduction overcoat, its power needed for motion, preferably adopt can as required greatly electrical motor and so on the driving engine (19) of amplitude adjustment rotative speed provide.But also can directly introduce the high speed train sustainer, main engine part rotary powers such as high ferro to drive.
In the drag reduction overcoat most external of the high speed train front and rear portions such as high ferro, made drag reduction overcoat outer shell (3), gap (4) profile is moved outside the gas-liquid on its surface, that can draw in similar Figure 20 is such, be made as between different ribbon outer shell band, there is no different outer shell bar interband connector (38) completely, but have complete regular parallel arrange large length gas outside move gap (4) structure.
Gap (4) is moved outside the gas on drag reduction overcoat outer shell (3) surface, that also can draw in similar Figure 19 is such, be made as between different outer shell band, there is different outer shell bar interband connector (38), outside the equal length ribbon gas that complete regular parallel is arranged, move the structure of gap (4).
Gap (4) is moved outside drag reduction overcoat outer shell (3) surface gas, that also can draw in similar Figure 21-22 is such, at ribbon drag reduction overcoat outer shell (3) outside face, make the distribute regular parallel of different outer shell bar interband connector (38) of tool product shape to arrange and move gap (4) outside gas, thus move gap (4) outside the gas of the drag reduction outer jacket surface made, become and have the little segmentation structure of rule of parallel interval distribution characteristics one by one.
Gap (4) is moved outside the gas on drag reduction overcoat outer shell (3) surface, also drag reduction sleeve surface can be had different outer shell bar interband connector (38), or not there is different outer shell bar interband connector (38), strictly all rules is laterally arranged in parallel and moves the longitudinal band of gap (4) outside gas, is made as tool and is in tilted layout each other the structure of feature.
When drag reduction overcoat is installed in the front portion of the high speed trains such as high ferro, can similar Fig. 1-2, draw in 4 such, by the outside face of drag reduction overcoat outer shell, making with the glass window flush with outer surface of driving compartment front portion.Also can still as now by procephalic for car rectification centrum district outside face, same plane is made as with the outside face of observation window, then after making drag reduction overcoat outside rectification centrum district, in the present observation window outside position concordant with drag reduction overcoat outer shell, one deck glass is installed again, to make the air in drag reduction overcoat medial movement, by the gap between two layers of glass, conveying in the drag reduction overcoat rearward still existed further.Also can as in Fig. 4 draw, by the drag reduction overcoat outer shell of drag reduction overcoat forefront upper surface, extend to the position near train forefront near top, and at the topmost position of such drag reduction overcoat, radar, infrared or latent acknowledger (28) that one replaces observation window (9) are installed.
At the almost whole outside face of the high speed trains such as high ferro, or in the high speed train such as whole high ferro at anterior drag reduction overcoat rear, external rear face position, the tool installed become whirlpool drag reduction casing sheets fairing, its topmost component part, be by one-tenth whirlpool drag reduction casing sheets (15), jointly form with the installation permanent seat base part (40,41) installing them.But interior flowing gas division board (14), is also that tool becomes within the drag reduction casing sheets fairing of whirlpool, can carries out the important composition parts of selectivity use.And become within the drag reduction casing sheets fairing of whirlpool at tool, flowing gas division board (14) in preferably all making or installing.
Become in the drag reduction casing sheets fairing of whirlpool at tool, most important constituent elements is its outermost one-tenth whirlpool drag reduction casing sheets (15), the profile of one-tenth whirlpool drag reduction casing sheets although it is so, as the author 201410393140.x, 201410460546.4, in 201410529048.1 patent applications as described in, the resemblance that many kinds are different can be made as.And the one-tenth whirlpool drag reduction casing sheets of these different profiles, all can become in the drag reduction casing sheets fairing of whirlpool to make for realizing drag reduction object at tool.But there is most the one-tenth whirlpool drag reduction casing sheets profile of practicality, probably or as in illustrations 23-28 draw, the contour structures feature being made as complete rectangular strip band shape may be better.
Become in the drag reduction casing sheets fairing of whirlpool at tool, although for the installation permanent seat base part (40,41) being mounted to whirlpool drag reduction casing sheets (15), can there is bar-shape that permanent seat (41) is installed, with discrete, the large type structure of permanent seat (40) two is installed, but they are all the pedestal base parts that may be used for installing outside one-tenth whirlpool drag reduction casing sheets (15), and it becomes the installation method in the drag reduction casing sheets fairing of whirlpool to be also identical at tool.This two class installs the difference between permanent seat base part (40,41), whether be only to be fixed into whirlpool drag reduction casing sheets by install, originally should be installation permanent seat (40) base part of discrete one by one, by increasing considerably length, and be interconnected to non-uniform thickness or completely uniform integraty belt structure.
As for becoming at concrete tool in the drag reduction casing sheets fairing of whirlpool, although can draw in similar Figure 23-25 such, will become whirlpool drag reduction casing sheets (15), and be fixed on discrete and install outside permanent seat (40).That also can draw in similar Figure 26-28 is such, adopts bar-shape to install permanent seat or similar device with it, fixes one-tenth whirlpool drag reduction casing sheets (15) in outside.
If from increasing into whirlpool drag reduction casing sheets (15), the structural stability aspect of installation and use process is considered, become in the drag reduction casing sheets fairing of whirlpool at various tool, should be best to adopt the bar-shape drawn in similar Figure 26-28 to install permanent seat (41).If but from the viewpoint of improving the drag-reduction effect of fairing, the installation permanent seat class device being fixed into whirlpool drag reduction casing sheets is then installed, should be adopt discrete in class Figure 23-25 to install permanent seat (40) or by the one-tenth whirlpool drag reduction casing sheets outside fairing, the discrete be arranged near outermost near top installs permanent seat drag-reduction effect may be better.
In the anterior rectification centrum district of the high speed train such as high ferro, and in drag reduction overcoat rear, external rear face, made tool becomes whirlpool drag reduction casing sheets fairing.That can draw in similar Figure 23-25,27-28 is such, is fixed on becoming whirlpool drag reduction casing sheets the outer surface portions that any one installs permanent seat (40,41).That also can draw in similar Figure 26 is such, permanent seat (40,41) outermost near top position will be installed, extend outwardly into into outside the drag reduction casing sheets of whirlpool, the class ribbon making lateral length larger becomes whirlpool drag reduction casing sheets, is divided into the strip one by one that length is relatively short.To improve the structural stability that the high speed train appearance institute tool for mountings such as high ferro become whirlpool drag reduction casing sheets fairing.
At positions, rectification centrum district of high speed train head such as high ferros, or headstock install in the train at drag reduction overcoat rear, external rear face position, carry out making or install the fixing rear tool used and become whirlpool drag reduction casing sheets fairing, can as in Fig. 1-4,23-28 etc. draw, tool lining up between the drag reduction casing sheets of whirlpool in the difference in air motion direction compared with Large space, install interior flowing gas division board (14) additional.Also interior flowing gas division board (14) can not be installed additional at position, such interval.May with as in 23-28 draw, line up position, interval between the drag reduction casing sheets of whirlpool in fairing outside face difference, when adding interior flowing gas division board (14), drag-reduction effect may be best.
Interior flowing gas division board (14) tool become install in the drag reduction casing sheets fairing of whirlpool time, interior flowing gas division board (14) uppermost margin like this, should be slightly closer from one-tenth whirlpool drag reduction casing sheets (15) Edge Distance in its front, and away from one-tenth whirlpool drag reduction casing sheets (15) Edge Distance at its rear some.So just can cause gaseous matter, enter inner side gas mobile space (44) time inflow entrance larger, and gas-liquid overflow inner side gas mobile space (44) time flow export relatively smaller.Thus extraneous gas material can be made, and more convenient when flowing into from position, drag reduction casing sheets front and back, the one-tenth whirlpool opening in fairing or flow out, also make fairing can realize better drag-reduction effect simultaneously.
The kinematic velocity of the high speed trains such as high ferro is higher, the tool making at its outside face or install and use becomes whirlpool drag reduction casing sheets fairing, line up between the drag reduction casing sheets individuality of whirlpool in the difference of its sense of motion, it is more relatively larger that spaced distance just should make.The air-flow caused to adapt to improve with kinematic velocity, gas mobile space (44) inside fairing, quantity when moving constantly increases feature fast.
Because the high speed Train motion speed such as same principle high ferro are faster, at Rapid train compartment outer surfaces such as these high ferros, the tool installed becomes within the drag reduction casing sheets fairing of whirlpool, become whirlpool drag reduction casing sheets (15) and the spacing distance inside it between car body outside face, what also should make wants more relatively large.By inner side gas mobile space (44) between both increases highly, to promote that the flowing velocity of air-flow in inner side gas mobile space (44) improves carrying out drag reduction.
The high speed train outside faces such as this external high ferro, the tool installed becomes in the drag reduction casing sheets fairing of whirlpool, suitably increasing into whirlpool drag reduction casing sheets (15), and after the spacing distance between the car body outside face inside it, also can become inner side, whirlpool drag reduction casing sheets (15), various installation permanent seat (40,41) base part outside face and the car body outside face in inside, the drag reduction paste layer (16) of some different profiles is all installed.And in inner side gas mobile space (44) becoming whirlpool drag reduction casing sheets, some different outer form drag bodies (17) are set.Therefore cause in inner side gas mobile space (44), increase considerably the friction drag of gas movement, be in fact conducive to increasing substantially tool and become whirlpool drag reduction casing sheets fairing drag-reduction effect.
Become inside the drag reduction casing sheets of whirlpool in gas mobile space (44), the resistance body (17) installed; And become inside whirlpool drag reduction casing sheets, permanent seat base part outside face and inside car body outside face be installed, the drag reduction paste layer (16) installed.Their anterior windward side (namely they are with the rear portion, direction of a Train motion) side surface, should be made as the profile that can increase considerably gaseousness motion of matter resistance.But at they rear portion lee face one side external surfaces, then should make can the milder fairing shape profile of significantly drag reduction.Stronger counter motion resistance (being the thrust can offsetting real resistance in fact) object must be produced to realize it.
In order to carry out drag reduction to greatest extent, between the different compartment of the high speed train such as high ferro to be interconnected connector (46) between different compartment, position outside, also can make tool and become whirlpool drag reduction casing sheets fairing (15).
Because the author is to connector (46) between the compartment between the different compartment of the high speed trains such as high ferro, how interconnective concrete structure is not clear between different compartment, so the Jian Jucheng whirlpool, compartment drag reduction casing sheets fairing (15) of drawing in Figure 33-36, structurally there is certain imagination, but except the concrete structure connected between different compartment and link up with, draw in accompanying drawing by one-tenth whirlpool drag reduction casing sheets mounting bracket (45), be interconnected rib (49), mounting part part and S. A. (51), the two torque spring (48) of tool shell protection, become whirlpool drag reduction casing sheets (15) five major part, Jian Jucheng whirlpool, the compartment drag reduction casing sheets fairing of common formation, the author think structure be substantially also comparative maturity can application structure.
As for connector (46) structure between the different compartments between different compartment, and the connection between its from different compartment between connector (46), although the author also cannot accurately draw now, no matter but their profile with figure in drawn much differences, Jian Jucheng whirlpool, the compartment drag reduction casing sheets fairing drawn in Figure 33-36 realizes the part of anti-drag function, its structure may all not need to carry out large amendment, so the author thinks Jian Jucheng whirlpool, the compartment drag reduction casing sheets fairing drawn in Figure 33-36, tool that exactly can be practical becomes whirlpool drag reduction casing sheets fairing.
At high speed train outside face or anterior region such as high ferros, after the drag reduction overcoat (3) of tool for mounting admission port (1), because moving the outer shell surface between gap (4) outside the different adjacent gas of drag reduction sleeve surface, lower in the front height of sense of motion, the class fairing formula profile that rearward height is higher, so enter the gaseousness material within drag reduction overcoat from admission port (1), can be as interior in Figure 37 draw, move gap (4) outside gas constantly by drag reduction overcoat outer shell (3) surface and carry out effusive eruption, thus it is outside at drag reduction overcoat outer shell (3), forming inner side is comparatively slow nearly horizontal rearward movement gaseousness material layer, secondary internal layer is eddy current (54) property motion material layer, outside is only the feature of carrying out high speed relative motion approximately level gaseousness material layer again.Such nature will cause extraneous gas material, is almost again directly to contact with each other with Rapid train compartment outer surfaces such as high ferros, is inevitable so can carry out significantly drag reduction.
And all car body outside faces at rear, the high speed trains such as high ferro anterior head position rectification centrum district, and in all compartments at drag reduction overcoat rear, head position, external rear face, after tool for mounting becomes whirlpool drag reduction casing sheets fairing, because of a large amount of gaseousness materials, can be as interior in Figure 38 draw, in a large number from becoming whirlpool drag reduction casing sheets anterior and interior flowing gas division board (14) rear, after gaseousness Commodity flow entrance enters in a large number, again from becoming drag reduction casing sheets rear portion, whirlpool and interior flowing gas division board (14) front, gaseousness material flow outlet effusive eruption and going out, thus equally also whirlpool drag reduction casing sheets fairing can be become outside at tool, forming inner side is comparatively slow nearly horizontal motion gaseousness material layer, secondary internal layer is eddy current (54) property motion material layer, outside is only the feature of carrying out at a high speed relative motion gaseousness material layer again, such nature will cause the gaseousness material of its outside, directly can not contact with each other with high speed train outside faces such as high ferros again, so can significantly also be inevitable by drag reduction.
