TORQUE ESTIMATION APPARATUS FOR VERTICAL TAKE-OFF AND LANDING AIRCRAFT, VERTICAL TAKE-OFF AND LANDING AIRCRAFT, TORQUE ESTIMATION PROGRAM FOR VERTICAL TAKE-OFF AND LANDING AIRCRAFT, AND TORQUE ESTIMATION METHOD FOR VERTICAL TAKE-OFF AND LANDING AIRCRAFT

摘要

This invention easily estimates the amount of a utilizable torque in real time based on limited engine performance parameters, regardless of abrupt variations in the engine performance. A torque estimation apparatus (12) of a helicopter (10) stores in a storage apparatus (14) a measurement point that is a measured value of the torque of an engine (28) with respect to a measured value of an engine performance parameter that relates to performance of the engine that rotates a rotor (26) together with a time at which the measurement point is measured, generates an approximate expression based on the measurement point that is stored in the storage apparatus (14), and estimates the amount of a utilizable torque based on the generated approximate expression.

1. A torque estimation apparatus for a vertical take-off and landing aircraft, comprising:
a storage apparatus that stores a measurement point that is a measured value of a torque of an engine with respect to a measured value of a parameter relating to performance of the engine that rotates a rotor, together with a time at which the measurement point is measured; a generation portion that generates an approximate expression based on the measurement point that is stored in the storage apparatus; and an estimation portion that estimates an amount of the torque that is utilizable based on the approximate expression that is generated by the generation portion.
