Abstract
The power available from a gas turbine engine is accurately determined by correcting predicted torque and gas generator speed for variations from normal of engine performance. The correction function is adaptively updated on-line by comparing actual and predicted values of torque and speed, storing any differences and summing the stored differences with the predicted values during the determination of power available.
