ELECTRIC PROPULSION SYSTEM CONTROL APPARATUS

Japanese Patent JP2022130817

A

To detect the air stream speed and air stream direction to a machine body of an electrified aircraft highly accurately without cost increase and weight increase, and quickly control the attitudes of an electric propulsion system and the machine body to the fluctuations of the air stream speed and the air stream direction.SOLUTION: An electric propulsion system control apparatus comprises: a first air stream speed measurement unit mounted on a machine body of an aircraft and having a first propulsion system parameter detection part which detects a propulsion system parameter being a parameter of an electric propulsion system that is driven by an electric motor and rotates around a rotational axis and a first air stream speed calculation part which calculates the first air stream speed being the air stream speed to the first direction being the direction of the rotational axis on the basis of the propulsion system parameter; a second air stream speed measurement unit which is mounted on the machine body and measures the second air stream speed being the air stream speed to the second direction different from the first direction; and an air stream calculation unit which calculates the air stream speed and air stream direction to the machine body on the basis of the first direction and the first air stream speed, and the second direction and the second air stream speed.SELECTED DRAWING: Figure 3
