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...
