Abstract

The invention relates to a gas-liquid hybrid power driving device with a buffer function for driving opening of an emergent door of an aircraft. The buffer function in a traditional aircraft emergency system is realized by a buffer, and the power driving function is realized by an independent power driving device, so that the traditional aircraft emergency system has the defects of more parts, low reliability, large weight volume and high fault rate and cost. The gas-liquid hybrid power driving device realizes stable opening of the emergent door of the aircraft in an emergency state through a gas-liquid hybrid power driving mode. The gas-liquid hybrid power driving device with the buffer function is applied to the aircraft, has such advantages as light weight, simple structure, high integration, high reliability and large reduction of ground maintenance work, and is obvious in economic benefit. The gas-liquid hybrid power driving device with the buffer function is higher in economic application value.

Description

technical field [0001] The invention relates to a gas-liquid hybrid driving device with a buffer function, which is used to drive the opening of an emergency door of an aircraft. Background technique [0002] In the current aircraft emergency system, the buffer function is realized by the buffer, and the power driving function is realized by an independent power driving device, which has the disadvantages of many components, low reliability, large weight and volume, high failure rate and high cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to realize the stable opening of the emergency door of the aircraft under the emergency state through the gas-hydraulic hybrid drive mode. [0004] The gas-liquid hybrid driving device with buffer function of the present invention is used to drive the opening of the emergency door of the aircraft, and the device includes a joint, an actuator block, an actuator sealing joint, an infl...
