Electric pressurization type anti G suit

Abstract

The invention discloses an electric pressurization type anti G suit. A motor is adopted to drive a gear to rotate, so that a binding rope is wound on a winding wheel, so that the pressure control on atightening region is realized, meanwhile, an elastic device is arranged in the tightening region, so that the pressure of the tightening region is ensured to be consistent; when the motor receives aforward rotation signal, the motor rotates forwards, the tightening area is tightened by the binding rope, continuous pressure is applied to a limb of a pilot, so that the resistance of the blood vessel around the limb is immediately increased, the diaphragm is prevented from falling, so that the blood in the limb enters a brain, and the symptoms such as the high-altitude anoxia, the grey view andthe dark view of the pilot are prevented; and when the motor receives a reversal signal, the motor rotates reversely, the winding wheel rotates reversely, the binding rope is loosened, under the action of elasticity, the tightening area is loosened, and blood in the pilot flows normally. According to the electric pressurization type anti G suit, the air bag structure in the existing anti G suit is omitted, and the weight of the anti G suit is reduced, meanwhile, the problems of poor air permeability of the anti G suit and overlarge thermal load of the pilot are solved, and the man-machine combination efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of aerospace anti-G equipment, in particular to an electric pressurized anti-G suit. Background technique [0002] When fighter jets accelerate turns, climb, descend, etc., the blood in the pilot's body will be redistributed and concentrated in the lower limbs, which will cause insufficient oxygen supply to the brain, and symptoms such as high-altitude hypoxia, gray vision, and black vision will appear. Loss of consciousness will occur when flying, and if effective protective measures are not taken, it may cause serious flight accidents. [0003] The use of anti-G equipment is a common protective measure against high overload at home and abroad. The main function of the anti-G suit is to prevent or reduce the initial effect of positive acceleration on the vascular system and delay its effect. When the aircraft experiences a high acceleration, the oxygen supply device connected to the anti-g suit is activate...

Problems solved by technology

[0005] Aiming at the problems existing in the prior art, the present invention provides an electric pressurized anti-G suit, which tightens the anti-G suit to generate continuous pressure on the pilot's body by pulling the restraining rope through the motor, which solves the problem of the weight of the existing anti-G suit. Large, poorly ventilated problems
