AIRCRAFT CREW EMERGENCY RESCUE SYSTEM Russian patent published in 2020 - IPC B64D25/10

Abstract RU 2711100 C1

FIELD: rescue means.

SUBSTANCE: invention relates to emergency aircraft crew rescue systems. Emergency aircraft crew rescue system comprises telescopic pneumatic drive including movable pneumatic cylinder-accumulator (5) with compressed gas, movable pneumatic cylinder, fixed pneumatic cylinder and throttle device that controls gas supply to working cavity. Throttling device is made in the form of a self-adjusting thermal throttle including body bushing (1) with inlet through holes (2) and with outlet calibrated nozzle (3). Inside body bushing (1) a cylindrical thermal rod (4) is installed coaxially to the nozzle. One end of thermal rod (4) is fixed inside body bushing (1), and its other end occupies variable position relative to inlet section of calibrated nozzle (3), caused by varying length of thermal rod (4), which depends on its temperature, thereby forming varying flow area of annular throttling slot.

EFFECT: invention widens the range of operating temperatures of safe ejection without using a safety valve associated with the working cavity of the pneumatic drive.
