Problems solved by technology

[0003] The existing ejection seat stabilizer umbrellas have the following problems: 1) The parts of the stabilizer 2 have high precision requirements for processing and assembly dimensions, and the manufacturing process is poor; 2) In order to ensure stability, the area of ​​the stabilizer 2 accounts for the total area of ​​the canopy More than 30% of that, resulting in low aerodynamic performance of the seat stabilizer umbrella (drag coefficient is 0.28-0.42), and heavy weight

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] like image 3 and Figure 4 As shown, an ejection seat stabilized umbrella includes a canopy and an umbrella rope 4, and the canopy includes a first-level top panel 1, a second-level top panel 1, and a skirt panel 3 connected in sequence from top to bottom, and the skirt panel 3 is outward Curved, the first-level top panel 1 and the second-level top panel 1 are stitched at intervals to form a row of evenly distributed crescent holes 2, and the second-level top panel 1 and skirt panel 3 are stitched at intervals to form another row of evenly distributed crescent holes 2 The openings of the upper row of crescent holes 2 are located above and outside the top panel 1, the openings of the lower row of crescent holes 2 are located above and outside the skirt panel 3, and the crescent holes 2 in the same row are of the same size.

Abstract

The invention relates to an ejection seat stabilization parachute which comprises a canopy and parachute cords. The canopy comprises a primary top width, a secondary top width and a skirt width whichare connected sequentially from top to bottom, the skirt width bends outwards, a row of evenly distributed crescent holes are formed by stitching the primary top width and the secondary top width at intervals, another row of evenly distributed crescent holes are formed by stitching the secondary top width and the skirt width at intervals, openings of the crescent holes of the upper row are locatedin the upper outer side of the secondary top width, openings of the crescent holes of the lower row are located in the upper outer side of the skirt width, and the crescent holes on the same row areidentical in size. The ejection seat stabilization parachute is small in parachute opening forces, rapid in stabilization, high in stabilization, lightweight and simple in manufacture.

Description

technical field [0001] The invention relates to a parachute, in particular to an ejection seat stabilizing umbrella. Background technique [0002] Modern fighter planes are generally equipped with ejection seats, and after the ejection seats eject from the fighter plane, the stabilizer parachute opens to ensure the safe landing of personnel. In order to ensure the stability performance while exerting the deceleration performance, the ejection seat stabilizer umbrella is generally designed with a stable width structure, such as figure 1 and figure 2 As shown, the existing ejection seat stabilizer umbrella is mainly composed of a canopy and a parachute 3. The canopy includes a top panel 1 and a stabilizing panel 2. The stabilizing panel 2 bends inward. After the canopy is full, the top panel 1 produces aerodynamic resistance. , the stabilizing width 2 guarantees the stability, the parachute rope 3 transmits the aerodynamic load and keeps the canopy full of shape, and the to...
