A slotted inflatable ram parafoil

Abstract

The invention discloses a slotted inflatable ram parafoil which comprises a left parafoil and a right parafoil, the inner end of the left wing parafoil and the inner end of the right wing parafoil areprovided with ribless frame connecting bands, the upper wing surface at the inner end of the left parafoil is suturally connected with the upper wing surface at the inner end of the right parafoil. Aplurality of left side gathering rings and a plurality of left side umbrella ropes are arranged on the left side ribless frame connecting belt along the length direction, a plurality of right side gathering rings and a plurality of right side gathering rings are arranged on the right side ribless frame connecting belt along the length direction, the right side umbrella ropes pass through the corresponding left side gathering rings, and the upper end of the left side umbrella ropes passes through the corresponding right side gathering rings. According to the invention, the ram parafoil is gradually deploy from the middle to the two ends dure the falling process; the invention prevents the collapse failure of the ramjet parafoil when the ramjet parafoil is opened, makes the deployment process of the ramjet parafoil more stable, improves the reliability of the ramjet parafoil opening, improves the requirements of the service performance, improves the safety of the ramjet parafoil, improves the inflatability of the ramjet parafoil, and improves the gliding performance of the ramjet parafoil.

Description

technical field [0001] The invention relates to the technical field of airborne equipment, in particular to a slotted inflatable stamping parafoil. Background technique [0002] The stamped parafoil is a new type of parachute. It is a kind of flexible aircraft similar to the airfoil that is sewn up by the upper and lower layers of the micro-breathable material. The opening of the leading edge is used to inflate. It is generally believed that the middle air chamber is inflated first, and at the same time, after being filled with air, it will extend to the air chambers on both sides. Or openings are designed, and the purpose of the ribs is to maintain the external aerodynamic performance of the stamped parafoil. However, the opening design of the leading edge of a stamped parafoil is generally more complicated, and the cut angle, size, and position of the opening will have a great impact on the inflation performance of the stamped parafoil. The reliability of the dynamic par...
