It also has Flight Management Computer, the A differential pressure pick-up, B differential pressure pick-up and pitch reference, the A differential pressure pick-up is installed on the front air bag of aerostatics, the B differential pressure pick-up is installed on the rear gasbag of aerostatics, the signal output part of A differential pressure pick-up is electrically connected with the signal input part of Flight Management Computer, the signal output part of B differential pressure pick-up is electrically connected with the signal input part of Flight Management Computer, the signal output part of Flight Management Computer is electrically connected with the signal input part of airiness valve, the signal output part of Flight Management Computer is electrically connected with the signal input part of Bidirectional axial flow fan, pitch reference is installed on the aerostatics, and the signal output part of pitch reference is electrically connected with the signal input part of Flight Management Computer.
Advantage of the present invention:
1, when regulating aerostatics pressure and flight pitch attitude balance, do not need frequent unlatching or valve-off and blower fan, can prolong like this service life of system equipment, all right saving resource;
2, by adjusting aerostatics pressure and flight pitch attitude balance, can reduce the operation frequency of flight control system, can also alleviate operation load, guarantee that flight control is effectively normal, strengthen reliability, the safety of flight control system;
3, when valve or fan trouble occurring and can't work, can effectively regulate the inside and outside differential pressure of aerostatics and flight pitch angle attitude thereof, guarantee normally finishing of aerial mission.
Description of drawings
[0004]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, have A admission port and A air extractor duct on the front balloonet, the A choker relief valve is installed on the A air extractor duct, the A aeration blower fan is installed in A admission port place, have B admission port and B air extractor duct on the rear balloonet, the B choker relief valve is installed on the B air extractor duct, the B aeration blower fan is installed in B admission port place, it also has balloonet amount of air control apparatus, balloonet amount of air control apparatus is comprised of air stream siphunculus 5 and 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 installed on the air stream siphunculus 5, and between front balloonet 3 and rear balloonet 4, air stream siphunculus 5 is provided with airiness 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 installed on the front air bag of aerostatics, B differential pressure pick-up 8 is installed on the rear gasbag of aerostatics, the signal output part of A differential pressure pick-up 7 is electrically connected with the signal input part of Flight Management Computer, the signal output part of B differential pressure pick-up 8 is electrically connected with the signal input part of Flight Management Computer, the signal output part of Flight Management Computer is electrically connected with the signal input part of airiness valve 5-1, the signal output part of Flight Management Computer is electrically connected with the signal input part of Bidirectional axial flow fan 6, pitch reference 9 is installed on the aerostatics 1, and the signal output part of pitch reference 9 is electrically connected with the signal input part of Flight Management Computer.
Pressure is regulated control principle: after external command inputed to Flight Management Computer, Flight Management Computer compared 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: when the differential pressure of front balloonet 3 is lower than standard value, at this moment need open the forward balloonet 3 interior superchargings of A aeration blower fan.If this moment, A aeration blower fan fault can't be moved, then need to open the B aeration blower fan, open simultaneously airiness valve 5-1 and Bidirectional axial flow fan 6, air is added that from rear balloonet 4 front balloonet 3 is to obtain pressure rise.If differential pressure is too high, then need open the venting of A choker relief valve, when A choker relief valve fault can't be opened, can open the B choker relief valve equally, open simultaneously airiness valve 5-1 and Bidirectional axial flow fan 6, and with Air Reverse to being transferred to rear balloonet 4, until differential pressure meets the demands.
Flight control principle: after external command inputs to Flight Management Computer, Flight Management Computer gathers the pitch angle value by pitch reference 9, compare analysis according to required flight attitude information and pitch angle existing condition, when aerostatics pitch angle attitude satisfied the required attitude of external command, then directly output command moved to empennage servo driving multiaspect.If the required attitude of external command is not satisfied in the aerostatics pitch attitude, then adjust the pitch attitude of aerostatics by opening airiness valve 5-1 and Bidirectional axial flow fan 6.For example: the ideal pose when aerostatics rises is anterior to facing upward between 0-30 °, and the higher elevation angle that then requires of rate of climb is larger, otherwise then less.Flight Management Computer receives climb command, detect by pitch reference 9 whether pitch angle is "+", and satisfy the rate of climb requirement, if, can directly drive the action of empennage steering wheel primary control surface, if not, then to open airiness valve 5-1 and Bidirectional axial flow fan 6, with the air of front balloonet 3 backward balloonet 4 shift, simultaneously, drive the action of empennage steering wheel primary control surface, when pitch angle satisfies aerostatics rising needs, then stop air transfer.
