Abstract

See full text

A power-producing device, such as a ram air turbine, includes a controller that is used to control operation of a turbine of the power-producing device. The controller uses an input based on an airspeed of the aircraft as part of a control mechanism in the controller for controlling the turbine. For example controller may be used to control backpressure of the turbine, for example by controlling the angle of doors of that are used to adjust backpressure of the turbine. The control mechanism may include a PID controller, with the gain of one or more of the values of the PID controller being a function of the airspeed of the aircraft. In addition the control mechanism may include manipulating a setpoint as a function of load on the power-producing device. The power-producing device may be part of a detachable pod that is installed on the aircraft.
