Embodiment Construction

[0014] The accompanying drawings of the above specification show a specific embodiment of the present invention, and its structure and working principle are further described as follows.

[0015] An aerostat airbag automatic inflation and deflation air pressure adjustment system, comprising an aerostat main airbag 19, an auxiliary airbag 18 inside the main airbag, and an inflation and deflation air pressure adjustment device for the auxiliary airbag. The auxiliary airbag inflation and deflation air pressure adjustment device includes a differential pressure monitor 1 connected to a differential pressure sensor 2 at its input end, an inflation and deflation controller 3 composed of a pulse width signal generator 4, an inflation relay 5 and an inflation relay 6 , also includes blower fan 8 and steering gear 9. The control signal output of the differential pressure monitor 1 is connected to the control coils of the inflation relay 6 and the deflation relay 5 respectively. The co...

Abstract

The invention relates to an air pressure regulating system of an air bag of an aircraft, in particular to an automatic inflating and deflating air pressure adjusting system of an air bag of an aerostat. The system comprises a main air bag, an auxiliary air bag and an air pressure adjusting device. The air pressure adjusting device comprises a pressure difference monitor connected with a sensor and an inflating and deflating controller composed of a pulse width signal generator, an deflating relay and an inflating relay; control signals outputted by the pressure difference monitor are connected with control coils of the inflating relay and the deflating relay respectively, and control signals outputted by the inflating and deflating controller are connected with a fan and a steering engine. The system has the advantages that change values of air pressure differences in the air bags are detected by the sensor and compared to a set upper limit value and a set lower limit value by the pressure difference monitor, actuating signals of the relays are outputted, an internal circuit of the pulse width signal generator generates output potential, and control signals are outputted so as to control start and stop of the fan and the steering engine respectively; closed-loop control inflating and deflating air pressure difference adjusting effect is good; an adopted steering engine control valve is capable of saving power as compared with existing electromagnet control valves; an adopted brushless motor is safer than existing brush motors, and fire hazards are avoided.

Description

Technical field: [0001] The invention relates to the technical field of aerostats, in particular to an air pressure regulating system of an aerostat air bag. Background technique: [0002] Aerostats include buoyant airships and balloons with buoyant airbags, which can cause airbag gas leakage due to different buoyant heights, changes in the atmospheric temperature of the sky, or poor airtightness of certain parts. The air pressure difference inside and outside the airbag changes, which will affect and threaten the safe flight of the aerostat. The solution is to install an auxiliary airbag in the main airbag of the buoyancy device, and install an inflation and deflation device for the auxiliary airbag. The gas increases the pressure of the main air bag. When the air pressure in the main airbag rises, let the auxiliary airbag deflate to reduce its pressure, so as to stabilize and reduce the change of the pressure difference between the inside and outside of the buoyant airba...
