Embodiment Construction

[0009] Such as figure 1 Shown, the present invention comprises the high-pressure air storage tank (1) that is placed on the aircraft; Vent pipeline (2); Air bag (3); Exhaust valve (4); Compressor (5); Its feature also comprises connection (1 ), (4), (5) remote control elements and connecting wires (7), and the control of the operation of the entire system that is mainly composed of a computer controller to adjust the airbag inflation volume through remote control (1), (4), (5) System (6) constitutes. The working principle of the invention utilizes the buoyancy force generated by the specific gravity difference between helium and air as the auxiliary lift force of the aircraft. When the aircraft may fall due to a stall, the driver (remote control) activates the system switch, the compressed helium is released from the high-pressure air tank (1), and the air bag (3) is quickly ejected to form a certain volume of helium cluster, relying on the helium to air Buoyancy relies on t...

Abstract

The invention designs an anti-falling energy-saving auxiliary lift system for miniature aircrafts, using helium as a main body. The auxiliary lift system consists of a high-pressure gas storage tank, a gasbag, a compressor, an exhaust valve, an auxiliary pipeline, connecting lines and a control system. The invention adopts a technical principle that: when the stall of an aircraft can cause falling, a pilot starts a system switch (by self or remote control), and then compressed helium is released from the high-pressure gas storage tank to eject the gasbag rapidly and to form a helium mass with a certain volume, so as to avoid or slow down the falling of the aircraft, to reduce the impact force on ground in the moment of crash and to reduce the destruction of crash by means of the buoyancy force of the helium to the air and the weight of the aircraft. The system can pump the helium in the gasbag back to the high-pressure gas storage tank through the compressor or control the exhaust valve to exhaust so as to adjust buoyancy force. The control system automatically regulates the buoyancy force of the gasbag according to parameters of a sensor, so as to achieve the gravity balance and energy-saving flight of the whole aircraft.

Description

technical field [0001] The invention discloses an anti-drop energy-saving auxiliary lift system for a small aircraft created by utilizing the buoyancy force generated by the difference in specific gravity between helium and air. It belongs to the technical field of aircraft accessories. Background technique [0002] The aircraft is mainly a winged aircraft, which must rely on the lift or bearing capacity of the air to stay in the air; the aircraft with fixed wings mainly relies on the air lift generated by the flow velocity difference of the fluid caused by the cross-sectional curve of the wing as the bearing capacity of the body; the helicopter Mainly rely on the air lift generated by the rotor as the bearing capacity of the body; but what they have in common is that they rely on power to make the wing move at a relatively high speed with the air particles in motion so that the air can produce a moderate bearing capacity on the wing, so that the aircraft Reach the function...
