Abstract
A torque estimation apparatus that estimates an available torque of an engine of a helicopter includes: a storage device that stores therein first engine torque data before degradation of engine performance and second engine torque data after the degradation of the engine performance; and a control device that estimates, based on the first and second engine torque data, an available torque, and the control device executes: standardization processing of obtaining and standardizing present engine performance parameter and engine torque; engine performance factor calculation processing of calculating, based on the first and second engine torque data, an engine performance factor from the standardized engine performance parameter and engine torque; and available torque calculation processing of calculating, based on the engine performance factor, an available torque corresponding to present performance of the engine.
