High-efficiency controllable raising force generating device for gear raising parachutes and use method

Abstract

The invention relates to the technical field of air vehicles, and in particular relates to a high-efficiency controllable raising force generating device for supplying raising force for gear raising parachutes and a use method. The device comprises a load frame, switchable rope quick-pulldown devices, at least two lightweight pull-resistant connecting rope sets which have a certain length and are synchronously connected to the switchable quick-pulldown rope devices, the gear raising parachutes and initial raising force devices, wherein all the components are sequentially connected from bottom to top. The use method of the device is characterized in that the gear raising parachutes are driven to raise through the initial raising force devices with small raising force according to the air resistance rule; the plurality of gear raising parachutes are pulled down and released in turns to realize free raising; the gear raising parachutes are inflated with air to unfold and lowered down to fold in turns during the movement process; the gear raising parachutes which are inflated with air to unfold during being quickly pulled down move to generate high air resistance which reversely act on the load frame through the connecting ropes and the switchable rope quick-pulldown devices which is fixed to the load frame, thus generating continuous high raising force to the load frame.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a high-efficiency generating device for a wheel parachute capable of providing lift with controllable lift and a method for using it. Background technique [0002] Human beings have long had the ideal of flying freely in the air. With the advancement of technology in the world, various aircrafts emerge in endlessly. The operation of aircraft can generally be divided into three stages: take-off, level flight, and landing. During take-off, the aircraft needs to be able to generate a lift greater than its own gravity within a certain period of time. And a certain amount of forward power, when landing, the aircraft needs to be able to gradually reduce the lift in a controlled manner so that it can gradually descend to the ground instead of falling. Therefore, the most important and necessary essence of the aircraft is to continuously provide lift. How to generate a A controllable l...

Problems solved by technology

[0003] However, the above-mentioned lift generation methods all have many deficiencies. The static buoyancy of the hydrogen (or helium) airbag on the air requires a super large volume, and the pressure difference between the upper and lower sides of the moving wing requires heavy power equipment to generate lift, resulting in low efficiency. recoil requires more fuel
