Purpose
Thrust control actuator ПРТ-204 is intended for automatic conversion of low-power boosting signals, which arrive in the analogue form from the thrust control system, into angular displacement of engine control levers at a rate proportional to the control signal level. The actuator is basic equipment for a range of drives of similar purpose.
