Abstract
The utility model discloses a modular long and thin crooked aircraft inlet, including a plurality of tube -shape part, tube -shape part externally end to end, the tube -shape parts be connecting and the tube -shape parts that form by a plurality of slice part (1) externally, the edge of slice part be provided with flange (2), be connected through flange limit (2) and fastener (3) cooperation installation between slice part and the slice part, fastener (3) be threaded fastener. The beneficial effects of the utility model are that: the utility model discloses a make tube -shape part externally end to end, avoid that the intake duct is inside to be provided with connection structure and to cause the inside surface of intake duct to be influenced in the air admission intake duct by the arch for the air admission is more smooth and easy, also avoids the inside surface quality of intake duct to be destroyed.
Description
Technical field
This utility model is related to airplane air inlet pipe road, specifically, is a kind of combination type elongate curved airplane intake.
Background technology
Airplane intake is for the air needed for aircraft offer electromotor work, the smooth degree to its structure interior surface
Require with form accuracy high.Due to the needs of preliminary design of aircraft, some type airplanes（Such as invisbile plane）Air intake duct need
It is designed to elongated, bending shape.
Conventional airplane intake mainly has two kinds of versions at present：Panel beating combinative structure and composite are integrally tied
Structure.
The air intake duct of panel beating combinative structure is made up of the sheet part of sheet-metal formed.Due to the stiffness by itself of sheet metal part
It is poor, yielding, therefore the air intake duct inner surface configuration low precision being made up of sheet metal part.The fastening connected between each sheet metal part
Part has to pass through the inner surface of air intake duct and is installed, and causes air intake duct inner surface to there is large number of fastener head, enters
One step affects the surface quality of air intake duct inner surface, and there is securing member and come off and break the hidden danger of electromotor.For personnel cannot
Into it is elongated, bending air intake duct, also there is a problem of that the securing member apart from air intake duct port remotely cannot be installed.
Only one part composition of the integrally-built air intake duct of composite itself, without the need for connecting securing member used, because
The smooth degree and form accuracy of this inner surface is generally higher.As the mould of composite air intake duct is located in air intake duct
Portion, after composite solidification, in order to mould is taken out, it is block form to need Design of Dies.For entering for elongated shape
For air flue, according to composite overall structure, extremely complex mould is needed, mould is by dozens or even hundreds of
Individual module composition.Mould piecemeal quantity is excessive, causes that die cost is high, assembling is complicated, and after being dismounted for multiple times probably due to
Module wear, deformation and cause mould to scrap.Gap between module can also leave molding trace in air intake duct inner surface, affect
The smooth degree of air intake duct inner surface., the air intake duct of bending excessively elongated for shape, it is also possible to have anyway that piecemeal is all
The problem that mould can not be taken out.
Utility model content
The purpose of this utility model is to provide a kind of simple structure, be conducive to the combination type for passing through smooth air elongated
Bending airplane intake.
This utility model is achieved through the following technical solutions：A kind of combination type elongate curved airplane intake, including it is some
Individual cartridge, cartridge join end to end from outside.
Described cartridge is the cartridge formed from external connection by several flat parts.
The edge of described flat parts is provided with flange, between flat parts and flat parts by flange with it is tight
Firmware coordinates installation to be attached.
Described securing member is threaded fastener.
The inner surface of described cartridge is through cartridge made by NC milling.
Described cartridge outer surface is provided with several reinforcements.
This utility model compared with prior art, with advantages below and beneficial effect：
（1）This utility model is joined end to end from outside by making cartridge, it is to avoid air intake duct is internally provided with connection knot
Structure, causes air intake duct interior surface to have projection and affect air to enter in air intake duct, enables to air with this and enter more suitable
Freely, air intake duct interior surface quality is also avoided to be destroyed；
（2）This utility model forms cartridge from external connection by using several flat parts, is conducive to letter
Change the processing technique of cartridge, improve the crudy of cartridge, flat parts is avoided in air intake duct from external connection
Portion is provided with attachment structure, causes air intake duct interior surface to have projection and affect air to enter in air intake duct, is enabled to this
Air enters more smooth, also avoids air intake duct interior surface quality from being destroyed；
（3）This utility model is connected with appended claims by using flange, can ensure bonding strength while,
So that flat parts are replaceable, use cost can be saved with this, improve the service efficiency of part；
（4）This utility model can make inner surface smooth degree, form accuracy by using NC milling inner surface
Height, even if the combination of multiple flat parts will not also reduce the smooth degree and form accuracy of inner surface；
（5）This utility model can improve the intensity of flat parts by arranging reinforcement, to avoid which from being deformed, prolong
Service life of the present utility model is grown.
Description of the drawings

Fig. 2 is a kind of exploded perspective view of combination type elongate curved airplane intake；
Wherein 1-flat parts, 2-flange, 3-securing member.
Specific embodiment
This utility model is described in further detail with reference to embodiment, but embodiment of the present utility model is not
It is limited to this.
Embodiment 1：
As shown in Figure 1 and Figure 2, in the present embodiment, a kind of combination type elongate curved airplane intake, including several tubulars
Part, cartridge join end to end from outside, and described cartridge is to be formed from external connection by several flat parts 1
Cartridge, the edge of flat parts is provided with flange 2, between flat parts and flat parts by flange 2 with it is tight
Firmware 3 coordinates installation to be attached, and described securing member 3 is threaded fastener, by using several flat parts from outside
Connect and form cartridge, be conducive to simplifying the processing technique of cartridge, improve the crudy of cartridge, make lamellar
Part avoids air intake duct from being internally provided with attachment structure from external connection, causes air intake duct interior surface to have projection and affect air
Into in air intake duct, air is enabled to this and enters more smooth, also avoid air intake duct interior surface quality from being destroyed.
Embodiment 2：
On the basis of embodiment 1, in the present embodiment, the inner surface of described cartridge is through NC milling
And made by cartridge, by using NC milling inner surface, inner surface smooth degree, form accuracy can be made high,
Even if multiple flat parts combinations will not also reduce the smooth degree and form accuracy of inner surface, air circulation can be reduced with this
The resistance being subject to, ventilates more smooth.
Embodiment 3：
On the basis of embodiment 1, in the present embodiment, described cartridge outer surface is provided with several reinforcements, leads to
The intensity for arranging that reinforcement can improve flat parts is crossed, to avoid which from being deformed, the use longevity of the present utility model is extended
Life.
The above, is only preferred embodiment of the present utility model, and any pro forma limit is not done to this utility model
System, every any simple modification made to above example according to technical spirit of the present utility model, equivalent variations, each falls within
