A traction parachute inflatable stamping parafoil

Abstract

The invention discloses a traction parachute-opening inflatable stamping parafoil, which comprises a stamping parafoil, a guiding parachute and an auxiliary top strap, the guiding parachute is connected with the top of the stamping parafoil through the auxiliary top strap, and the rib in the middle of the parafoil is stamped The front edge is connected with a leading edge connecting buckle, and the middle part of the rib in the middle of the punched parafoil is connected with an intermediate connecting buckle; the upper end of the auxiliary leading belt is connected with the guiding parachute, and the lower end of the auxiliary leading belt is connected with a connecting buckle short belt and a connecting buckle Long belt, the lower end of the connecting buckle short belt is connected with the middle connecting buckle, the lower end of the connecting buckle long belt is connected with the leading edge connecting buckle, and a broken rope is connected between the lower end of the connecting buckle long belt and the leading edge connecting buckle. Realize the gradual deployment of the stamped parafoil from the middle to both ends during the falling process and the detachment of the stamped parafoil from the guide parachute after deployment, making the deployment process of the stamped parafoil more stable, improving the reliability and performance of the stamped parafoil, and improving Improve the safety of the ram parafoil, improve the inflation performance of the ram parafoil, and improve the gliding performance of the ram parafoil.

Description

technical field [0001] The invention relates to the technical field of aviation equipment, in particular to a towing and opening inflatable stamping parafoil. Background technique [0002] The stamped parafoil is a new type of parachute. It is a flexible aircraft similar to an airfoil, which is sewn up by the upper and lower layers of the micro-breathable material. However, the front edge of the stamped parafoil needs a cut. Inflate the entire air chamber to form a wing-like shape with gliding performance and maneuverability, while the size of the leading edge cutout has a greater impact on its performance. When the cutout is larger, the inflation performance is improved, but the glide performance is reduced. When it is small, the problem of leading edge collapse often occurs when the parachute is opened, so that the stamped parafoil cannot be inflated normally. The current method used to assist the inflation of the stamped parafoil is to install a small conventional parachu...

Problems solved by technology

[0002] The stamped parafoil is a new type of parachute. It is a flexible aircraft similar to an airfoil that is sewn together by the upper and lower layers of the micro-breathable material. However, the front edge of the stamped parafoil needs an incision. Inflate the entire air chamber to form a wing-like shape with gliding performance and maneuverability, while the size of the leading edge cutout has a greater impact on its performance. When the cutout is larger, the inflation performance is improved, but the glide performance is reduced. When it is small, the problem of leading edge collapse often occurs when the parachute is opened, so that the stamped parafoil cannot be inflated normally. The current method used to assist the inflation of the stamped parafoil is to install a small conventional parachute on the top of the parachute. The parachute assists the stamping parafoil to inflate during the parachute opening process, but after the stamping parachute is fully inflated, this type of parachute stays on the top of the stamping parachute and cannot be released by itself. Drag in the direction of flight will reduce the glide performance of the ram parafoil

Adding a forming support piece to the rib of the stamped parafoil greatly increases the weight of the stamped parafoil, which brings troubles to the packaging and folding
