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 being generated by 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 which represents a change in performance of the engine based on the measurement point that is stored in the storage apparatus; and
an estimation portion that estimates the maximum value of a torque which the engine can generate, based on the approximate expression that is generated by the generation portion.

Abstract
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.

11. A computer-readable recording medium in which a torque estimation program for a vertical take-off and landing aircraft is stored, the torque estimation program causing a computer to function as:
-
a reading portion that reads out a measurement point that is a measured value of a torque being generated by an engine with respect to a measured value of a parameter relating to performance of the engine that rotates a rotor from a storage apparatus in which the measurement point is stored together with a time at which the measurement point is measured; a generation portion that generates an approximate expression which represents a change in performance of the engine based on the measurement point that is read out; and an estimation portion that estimates the maximum value of a torque which the engine can generate, based on the approximate expression that is generated by the generation portion.
