DEVICE FOR CONTROLLING THROTTLE VALVE OF AIRCRAFT ENGINE Russian patent published in 2022 - IPC F02D9/02 F02D41/22 

FIELD: aviation.

SUBSTANCE: invention can be used in aircraft piston engines. A device for controlling a throttle valve of an aircraft engine contains electric engine (6) connected to controller (4) connected to valve position sensor (13). Valve position sensor (13) is connected to rotary element (12) connected to return spring (11). The device contains second electric engine (7) connected to second controller (5) connected to second valve position sensor (14). Second valve position sensor (14) is connected to rotary element (12). The device contains two planetary gearboxes (8), (9), summing gearbox (10), two electrical connectors (cylindrical knife connector, hereinafter – CKC1), (CKC2) and block (3) of external connectors and radio interference filters. Electrical connector (CKC1), electric engine (6), controller (4), planetary gearbox (8) and valve position sensor (13) form the main control channel. Second electrical connector (CKC2), second electric engine (7), controller (5), planetary gearbox (9) and position sensor (14) form a duplicate control channel. Planetary gearboxes (8), (9) are connected to summing gearbox (10) connected to return spring (11). Controllers (4), (5) are connected to block (3) of external connectors connected to electrical connectors (CKC1), (CKC2).

EFFECT: increase in the reliability of a device for controlling a throttle valve.
