Problems solved by technology
[0006] Since the installed power of the hatch actuation system is very large, the hydraulic system of the main engine needs to provide a relatively large peak power, which may even account for more than half of the total power of the hydraulic system of the whole machine, which brings a great burden to the hydraulic system of the main engine

The invention relates to a cabin door transient actuating device and system based on secondary regulation and a driving method. One embodiment of the device comprises a servo valve, a flow regulation mechanism and a variable displacement motor. The variable displacement motor comprises a swash plate and an output shaft. The servo valve comprises a control end, and the control end receives an external control instruction and drives the flow regulation mechanism based on the external control instruction. The flow regulation mechanism pushes the swash plate of the variable displacement motor under driving of the servo valve, and the dip angle of the swash plate is changed. The output shaft of the variable displacement motor is connected with a cabin door load and used for outputting torque for driving the cabin door load. By the adoption of the scheme, host power needing to be extracted is low, and therefore the problems that the working efficacy of an aircraft is reduced and the fighting ability of the aircraft is weakened probably due to fight for power with other airborne equipment are avoided.
Description
technical field [0001] The present application relates to the technical field of aircraft door drive, in particular to a door transient actuation device, system and control method based on secondary regulation. Background technique [0002] With the emergence of advanced airborne weapons and the design requirements for the simple aerodynamic shape of aircraft, the weapon equipment system of contemporary fighter jets has changed from the original external type to the internal type. Especially for the requirements of high stealth, supersonic cruise and super maneuverability of the new generation of fighter jets, the embedded loading of weapons has become an inevitable choice. Therefore just must open its weapon bay door to carry out weapon launch and drop bomb when fighter air combat and bomber drop. The key to the weapon's embedded loading technology is the hatch actuation system. It is characterized by large inertia and fast opening and closing, which requires instantaneou...
