Document Type and Number:
Japanese Patent JP2013203334
Kind Code:
A
Abstract:

To easily estimate a magnitude of an available torque from limited engine performance parameters in real time regardless of a rapid change in engine performance.

In a torque estimation apparatus 12 for a helicopter 10, a measuring point that is a measurement of a torque of an engine 28 which rotates a rotor 26, with respect to a measurement of an engine parameter relating to a performance of the engine is stored in a storage device 14 together with a time of measurement, an approximate expression is generated based on the measuring point stored in the storage device 14, and a magnitude of an available torque is estimated from the generated approximate expression.
