Description
Technical field
The present invention relates to a kind of parachute, and in particular to a kind of seat-stabilizer parachute.
Background technology
Modern opportunity of combat is typically equipped with ejector seat, and drogue opens guarantee personnel after ejector seat ejects from opportunity of combat
Safe falling.To ensure stability while deceleration efficiency is played, seat-stabilizer parachute generally is configured with stabilizing panel knot
Structure, as depicted in figs. 1 and 2, existing seat-stabilizer parachute are mainly made up of canopy and umbrella rope 3, and canopy is including top 1 and surely
Tentering 2, stabilizing panel 2 curves inwardly, and after canopy is full of, top 1 produces aerodynamic drag, and stabilizing panel 2 ensures stability, and umbrella rope 3 passes
Pass aerodynamic loading, keep canopy inflated shape, top 1, stabilizing panel 2 play the effect of single respectively.
Problems be present in existing seat-stabilizer parachute：1) Dimension Measurement of stabilizing panel 2, fitted position precision
It is required that high, anufacturability is poor；2) in order to ensure stability, the area of stabilizing panel 2 accounts for more than the 30% of the canopy gross area, thus
Cause the pneumatic efficiency of seat drogue relatively low (resistance coefficient is 0.28~0.42), and heavier-weight.
The content of the invention
It is an object of the invention to provide a kind of seat-stabilizer parachute, opening shock is small, and stable fast, stability is high, weight
Gently, it is simple to manufacture.
The technical solution adopted in the present invention is：
A kind of seat-stabilizer parachute, including canopy and umbrella rope, canopy include be sequentially connected from top to bottom one-level top width,
Two level top width and skirt width, skirt width are bent outwardly, suture shape uniform crescent moon in a row in interval between one-level top width and two level top width
Hole, interval sutures and forms the uniform crescent hole of another row between two level top width and skirt width, positioned at the opening position of the crescent hole of upper row
In the upper outer of two level top width, being open for crescent hole positioned at lower row is located at the upper outer of skirt width, with the crescent hole chi of row
It is very little identical.
Further, the length L of crescent hole outer ledge1The length L of/crescent hole inside edge2=1.12.
Further, the integral diameter D=0.16 of the length dimension L/ one-levels top width of skirt width and two level top width.
Further, two row's crescent holes correspond in different angle.
The beneficial effects of the invention are as follows：
In gas replenishment process, crescent hole can carry out good exhaust, reduce the opening shock of seat-stabilizer parachute,
Skirt width can produce righting moment, seat-stabilizer parachute is settled out faster, and during stable decline, crescent hole can be with
Canopy is set to be vented downwards, so as to produce certain lift, there is provided larger resistance coefficient, improve seat-stabilizer parachute
Stability, while umbrella rope transmits aerodynamic loading, keeps canopy inflated shape；It is to further improve to design two row's crescent holes
While seat-stabilizer parachute resistance efficiency (the pneumatic efficiency of seat-stabilizer parachute is higher, resistance coefficient be 0.70~
0.78), improve the interior flow field under canopy full state, improve stability；Because crescent hole has improved resistance coefficient and steady
It is qualitative, therefore skirt width raising resistance coefficient and stability, skirt width need not be relied on only to account for Parachute area (one-level top width, two level top width
With the gross area of skirt width) 20%, skirt width size is smaller, in light weight；Space between one-level top width, two level top width and skirt width
Close, reassembled together after sewing can be respectively completed, manufacturing process is simpler.
Brief description of the drawings

Fig. 2 is the structural representation of existing seat-stabilizer parachute.
Fig. 3 is the schematic diagram when embodiment of the present invention is full of.
Fig. 4 is the structural representation of the embodiment of the present invention.
In figure：1- pushes up width；2- crescent holes；3- skirt width；4- umbrella ropes.
Embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 3 and Figure 4, a kind of seat-stabilizer parachute, including canopy and umbrella rope 4, canopy include from top to bottom according to
One-level top 1, two level top 1 and the skirt 3 of secondary connection, skirt 3 are bent outwardly, are spaced between one-level top 1 and two level top 1
Shape uniform crescent hole 2 in a row is sutured, interval sutures and forms the uniform crescent hole of another row between two level top 1 and skirt 3
2, the upper outer on two level top 1 is located at positioned at the opening of the crescent hole 2 of upper row, the opening positioned at the crescent hole 2 of lower row is located at
The upper outer of skirt 3 is identical with the size of crescent hole 2 of row.
In the present embodiment, the length L2=1.12 of the inside edge of length L1/ crescent holes 2 of the outer ledge of crescent hole 2, skirt
3 length dimension L/ one-levels top 1 and the integral diameter D=0.16 on two level top 1, two row's crescent holes 2 are in different angle
Correspond.
In gas replenishment process, crescent hole 2 can carry out good exhaust, and the parachute-opening for reducing seat-stabilizer parachute is moved
Carrying, skirt 3 can produce righting moment, seat-stabilizer parachute is settled out faster, during stable decline, crescent hole
2 can be such that canopy is vented downwards, so as to produce certain lift, there is provided larger resistance coefficient, it is steady to improve ejector seat
Determine the stability of umbrella, while umbrella rope 4 transmits aerodynamic loading, keeps canopy inflated shape；It is to enter to design two row's crescent holes 2
(the pneumatic efficiency of this seat-stabilizer parachute is higher, resistance coefficient while one step raising seat-stabilizer parachute resistance efficiency
For 0.70~0.78), improve the interior flow field under canopy full state, improve stability；Because crescent hole 2 has improved resistance
Coefficient and stability, therefore the raising resistance coefficient of skirt 3 and stability, skirt 3 need not be relied on only to account for Parachute area (one-level top width
1st, the gross area of two level top 1 and skirt 3) 20%, the size of skirt 3 is smaller, in light weight；One-level top 1, the and of two level top 1
Suture is spaced between skirt 3, is reassembled together after sewing can be respectively completed, manufacturing process is simpler.
It should be appreciated that for those of ordinary skills, can according to the above description be improved or converted,
And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
