Embodiment Construction

[0026] figure 1 Shown is a schematic diagram of a retractable tension rope parachute, the umbrella rope (1) replaced by the retractable tension rope in the figure, the connecting rope (2) replaced by the retractable tension rope, and the binding rope ( 3), the increased gas supply system consists of a gas storage bottle (12), a gas distribution device (13), and a ventilation hose (14). Gas storage bottle (12), gas distribution device (13) are fixed on the airdrop (6), gas storage bottle (12), gas distribution device (13), ventilation hose (14) communicate with each other, ventilation hose (14 ) is communicated with the air bag port (18) on all retractable tension ropes on the umbrella system, and the ventilation hose (14) is connected together with the stressed suspenders (15) on all the retractable tension ropes that pass through. If the air supply system is filled with pressurized gas in the parachute (1), connecting cord (2), and binding cord (3), the parachute cord (1), c...

Abstract

The invention claims an internal shrinking tensile rope parachute. The basic idea of the invention is as follows: using an internal shrinking tensile rope, which can be shortened after being aerated and can produce tensile force and can be prolonged after being stretched and can compress air, to replace the rope tape of the existing parachute system, or adding an internal shrinking tensile rope on the parachute system, and adding a set of air supply system and a sensing control system. Said replaced rope tapes comprise a parachute lanyard (1), a connection rope (2), a binding rope (3), a close rope (4) and so on. When the parachute system with said structure is used, the contraction and stretching of the rope tape is controlled to control the size of the tensile force produced by the rope tape so as to change the shape, position relationship and aerodynamic characteristic of the parachute system to further reduce overload produced on the parachute system, and change the motion speed and direction of the parachute system and reduce landing speed of air-dropped articles. The parachute system with said structure is added with new functions and can probably reduce weight of the parachute system.

Description

technical field [0001] The invention relates to a parachute, in particular to a parachute composed of a canopy, a parachute, a reinforcing belt and a connecting rope. Background technique [0002] In the parachutes recorded, reported and used at present, the rope on the umbrella is basically to add twisted rope and braided rope. This kind of parachute is overloaded greatly during use, and canopy area is bigger, is difficult to manufacture, is difficult to control, and landing speed is faster. Chinese patent specification CN101823560A discloses a multifunctional parachute. The multifunctional parachute is mainly composed of a canopy, a parachute, an air storage tank, a catheter, a valve, and an airbag on the canopy. Filled with a lighter-than-air gas to create lift, the device doubles as a float valve when dropped into water. Since the airbag will produce effective buoyancy, its volume and weight will be very large, so this type of device not only increases the weight, but ...
