Embodiment Construction
[0025] The purpose of the present invention is to provide an auxiliary fuel system that reduces system weight, equipment and maintenance costs to aircrafts that have low frequency of use of auxiliary fuel tanks and no special requirements for transit time, and controls the fuel consumption sequence and center of gravity of the aircraft, reducing Heat source in the small auxiliary tank.
[0026] The auxiliary fuel system according to the present invention mainly includes:
[0027] Transfer the fuel in the auxiliary fuel tank 30 to the transfer subsystem in the left main fuel tank 10 and the right main fuel tank 20 at the same time;
[0028] A refueling subsystem for adding fuel to the auxiliary fuel tank;
[0029] And the auxiliary fuel tank ventilation subsystem to ensure the pressure in the auxiliary fuel tank.
[0030] The transmission subsystem mainly consists of the transmission power source components in the auxiliary fuel tank, the transmission control components in th...
