Abstract

The invention provides a hydraulic pressurizing energy storage cabin door actuating system. The hydraulic pressurizing energy storage cabin door actuating system comprises a pressurizing energy storage device and a transmission device (2). The pressurizing energy storage device comprises a one-way pump-both-way motor (3), a first one-way valve (4), an energy accumulator (5), a switching valve (6), a servo valve (7), a second one-way valve (8) and an oil tank (9). The one-way pump-both-way motor (3) can suck oil from the oil tank (9) through the second one-way valve (8), and the energy accumulator (5) is filled with oil through the first one-way valve (4). The switching valve (6) is used for controlling the on-off states of an oil path between the energy accumulator (5) and the servo valve (7). The servo valve (7) is used for controlling oil in the energy accumulator (5) to drive the one-way pump-both-way motor (3), and the one-way pump-both-way motor (3) is further used for driving the transmission device (2).

Description

technical field [0001] The invention belongs to the technical field of hatch actuating systems, and in particular relates to a hydraulic pressurized energy storage hatch actuating system. Background technique [0002] At present, several major military powers in the world are developing or have successfully developed fourth-generation fighter jets. Due to the need for stealth and reduced resistance, the buried bomb bay layout has been widely used by new fighter jets. The key to the weapon's embedded loading technology is the hatch actuation system. The hatch door actuation system embedded in the bomb bay is an important new actuation system for the fourth-generation aircraft compared to the third-generation aircraft. It is characterized by large load, large inertia and fast opening and closing, which leads to the need for instantaneous high power to open and close the hatch. [0003] At present, the traditional cabin door driving method adopted at home and abroad is the on...
