Background technology
Dirigible is " be lighter than air, advanced by power, be steerable " aircraft.It can long-time aloft suspension stay.
Be divided into rigid airship (RIGID AIRSHIP), blimp and blimp (NON-RIGID AIRSHIP or BLIMP) again according to the different dirigibles of airbag structure.
The air bag of blimp is made with materials such as air tight dirigible fabrics.Be flexible, soft when not inflating.Be full of become behind the buoyancy gas firm.Generally, the gaseous tension in the blimp air bag will be higher than outside atmospheric pressure, and it is firm that this difference of pressure makes that air bag becomes, and fold or distortion can not take place under aerodynamic loading.
The shape of air bag has a significant impact for the overall performance of dirigible, and the air bag desired shapes is conventional ellipse or olive-type.Dirigible to the major requirement of air bag is: streamlined contour, to reduce the maneuvering performance of air resistance and raising dirigible; Can bear the load that the clean power of aloft air, power and propelling unit produce.
General dirigible air bag also designs one or more balloonets except that main gasbag of design, control system by gaseous tension in inlet and outlet valve and the balloonet makes airship flight height and variation of ambient temperature regulate the air bag internal pressure, plays simultaneously to be dirigible trim effect under the different loads state.For blimp, the pressure regulating system of air bag is very important, because this is the requisite means that keep dirigible airbag structure shape, guarantee airbag safety pressure and finish aerial mission.
Summary of the invention
The purpose of this utility model is to propose a kind of dirigible air bag pressure reduction automatically regulating control setup that is applicable to, after this air pressure adjustment control setup carries out the setting threshold judgement by the air bag inside and outside differential pressure to sensor acquisition, output On/Off signal is controlled air inlet valve, blow off valve respectively, make air bag keep desired shapes and safe pressure, guarantee the safe and efficient flight of dirigible aloft.
The utility model is a kind of dirigible air bag pressure reduction automatically regulating control setup that is applicable to, the blowing engine aspirating end is connected with the end A of air inlet valve, and the end B of air inlet valve is connected with dirigible air bag air inlet port; The exhaust port of dirigible air bag is connected with the end A of blow off valve, and the end B of blow off valve is the gas discharge end; On the dirigible air bag sensor is installed, the mouth of sensor is connected on the air pressure adjustment controller, and the blower fan control end of air pressure adjustment controller is connected with blowing engine.
The pressure reduction automatically regulating control setup advantage of the utility model dirigible air bag is: (1) chooses pic chip and the flash memory combination is used, and improved automatic voltage-controlled control accuracy to the air bag internal differential pressure; (2) mode that combines with control program by micro controller system has alleviated the weight of mechanical type gasbag pressure control setup commonly used at present effectively.
