Abstract

The invention provides a pyrotechnic gas-liquid buffer damper which comprises a first shell, a pyrotechnic gas device, a floating piston member, a first one-way valve, buffer liquid and a piston rod assembly, wherein the first shell is provided with a first containing cavity and a second containing cavity; the pyrotechnic gas device is arranged at one end of the first shell, and the pyrotechnic gas device is used for generating buffer gas; the floating piston member is movably arranged in the first shell; the first one-way valve is arranged on the floating piston member, and the first one-wayvalve is used for preventing the buffer gas from moving from the second containing cavity to the first containing cavity; the buffer liquid is contained in the second containing cavity; the piston rodassembly is movably arranged in the second containing cavity, and is provided with a first through hole; and the buffer damper provides liquid buffer damping force by enabling the buffer liquid to flow through the first through hole. With application of the technical scheme, the technical problem of contradiction between high buffering damping performance and high locking cost of a buffer and difficulty in ground operation and maintenance in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of buffers for aircraft, in particular to a pyrotechnic gas-liquid buffer damper. Background technique [0002] At present, there are two main types of buffers for aircraft: solid spring buffer dampers and fluid spring buffer dampers. The core components of solid spring buffer dampers are springs or rubber, and the core components of fluid spring buffer dampers are generally gas, liquid or Gas-liquid mixing. The solid spring buffer is based on the working principle of energy storage and release. It has the advantages of simple structure, reliable operation and convenient maintenance. It is mainly used for small aircraft and small-scale buffer damping, such as the buffer damping of small UAV landing gear. The liquid spring buffer belongs to the working principle of air compression and small hole throttling energy consumption, especially the gas-liquid buffer damper, which has the best efficiency and power ab...
