Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, the present invention includes front balloonet amount of air control apparatus and rear balloonet amount of air control apparatus, front balloonet amount of air control apparatus is comprised of A choker relief valve and A aeration blower fan, rear balloonet amount of air control apparatus is comprised of B choker relief valve and B aeration blower fan, on front balloonet, have A admission port and A air extractor duct, A choker relief valve is arranged on A air extractor duct, A aeration blower fan is arranged on A admission port place, on rear balloonet, have B admission port and B air extractor duct, B choker relief valve is arranged on B air extractor duct, B aeration blower fan is arranged on B admission port place, it also has balloonet amount of air control apparatus, balloonet amount of air control apparatus is by air stream siphunculus 5, Bidirectional axial flow fan 6, air stream siphunculus 5 two ends communicate with front balloonet 3 inner chambers and rear balloonet 4 inner chambers respectively, Bidirectional axial flow fan 6 is arranged on air stream siphunculus 5, between front balloonet 3 and rear balloonet 4, air stream siphunculus 5 is provided with circulation of air valve 5-1.
It also has Flight Management Computer, A differential pressure pick-up 7, B differential pressure pick-up 8 and pitch reference 9, A differential pressure pick-up 7 is arranged on the front air bag of aerostatics, B differential pressure pick-up 8 is arranged on the rear gasbag of aerostatics, the signal output part of A differential pressure pick-up 7 is electrically connected to the signal input part of Flight Management Computer, the signal output part of B differential pressure pick-up 8 is electrically connected to the signal input part of Flight Management Computer, the signal output part of Flight Management Computer is electrically connected to the signal input part of circulation of air valve 5-1, the signal output part of Flight Management Computer is electrically connected to the signal input part of Bidirectional axial flow fan 6, pitch reference 9 is arranged on aerostatics 1, the signal output part of pitch reference 9 is electrically connected to the signal input part of Flight Management Computer.
Pressure regulates control principle: external command inputs to after Flight Management Computer, and Flight Management Computer compares according to the aerostatics differential pressure value of differential pressure standard value and differential pressure pick-up (A differential pressure pick-up 7 and B differential pressure pick-up 8) collection.
For example: the differential pressure of front balloonet 3 during lower than standard value, at this moment needs to open the interior supercharging of balloonet 3 forward of A aeration blower fan.If now A aeration blower fan fault cannot be moved, need to open B aeration blower fan, open circulation of air valve 5-1 and Bidirectional axial flow fan 6 simultaneously, air is added to front balloonet 3 is to obtain pressure rise from rear balloonet 4.If differential pressure is too high, need to open the venting of A choker relief valve, when A choker relief valve fault cannot be opened, can open B choker relief valve equally, open circulation of air valve 5-1 and Bidirectional axial flow fan 6 simultaneously, and by Air Reverse to being transferred to rear balloonet 4, until differential pressure meets the demands.
Flight control principle: external command inputs to after Flight Management Computer, Flight Management Computer gathers pitch angle value by pitch reference 9, according to required flight attitude information and pitch angle existing condition, compare analysis, when aerostatics pitch angle attitude meets the required attitude of external command, directly output command moves to empennage servo driving multiaspect.If aerostatics pitch attitude does not meet the required attitude of external command, by opening circulation of air valve 5-1 and Bidirectional axial flow fan 6, adjust the pitch attitude of aerostatics.For example: ideal pose when aerostatics rises is anterior to facing upward between 0-30 °, and the higher elevation angle that requires of rate of climb is larger, otherwise less.Flight Management Computer receives climb command, by pitch reference 9, detect whether pitch angle is "+", and meet rate of climb requirement, if, can directly drive the action of empennage steering wheel primary control surface, if not, to open circulation of air valve 5-1 and Bidirectional axial flow fan 6, by the air of front balloonet 3 backward balloonet 4 shift, simultaneously, drive the action of empennage steering wheel primary control surface, when pitch angle meets aerostatics rising needs, stop air transfer.
