An electro-pneumatic automatic umbrella opener device

Abstract

The invention belongs to the automatic control technology of aviation lifesaving equipment, and relates to an electric-controlled pneumatic type automatic parachute opening device. The electric-controlled pneumatic type automatic parachute opening device comprises a cylinder body assembly, a piston assembly, and a bomb throwing assembly, wherein the cylinder body assembly comprises a cylinder body and a hoop, and the hoop sleeves the cylinder body; the piston assembly comprises a bracket, a piston and a pulley, wherein the bracket is fixed in an inner cavity of the cylinder body, the piston is movably arranged in the inner cavity of the cylinder body and is positioned above the bracket, and the pulley is arranged on the bracket; the bomb throwing assembly connected with an electric control mechanism is arranged in the cylinder body, and is positioned under the bracket; one end of a parachute cord is connected with a parachute opening pin of a parachute pack, and the other end of the parachute cord sequentially penetrates through a guiding hole in the top end of the cylinder body, the piston and a fixed pulley on the bracket to be fixed on the piston. Compared with conventional parachute opening devices, the automatic electric-controlled pneumatic type parachute opening device disclosed by the invention has the advantages that the automatic electric-controlled pneumatic type parachute opening device is low in volume weight and light in weight, the height and the time lag error can be precisely controlled in any lifesaving envelope curve, and the aviation safety lifesaving rate is effectively increased.

Description

technical field [0001] The invention belongs to the automatic control technology of aviation lifesaving equipment, and relates to an electronically controlled pneumatic automatic parachute opener device. Background technique [0002] The parachute opener is an important aviation life-saving equipment, which is used to start and cut the life-saving parachute rope and implement ejection life-saving. At present, the automatic umbrella opener is mainly composed of a power spring, a clock mechanism and a bellows, mainly relying on the automatic control technology that the spring provides power, the timing of the gear train clock mechanism and the deformation and displacement of the bellows. However, the existing automatic parachute opener is a purely mechanical product with low parameter control accuracy and unstable performance. In the lifesaving system, it cannot accurately realize ejection lifesaving within the envelope, so that the probability of safe lifesaving is low. Con...

Problems solved by technology

However, the existing automatic parachute opener is a purely mechanical product, its parameter control accuracy is low, and its performance is unstable. In the life-saving system, it cannot accurately realize the ejection life-saving within the envelope, so that the probability of safe life-saving is low.
