Title:
ELECTRIFIED AIRCRAFT AND REGENERATED ELECTRIC POWER CONTROL METHOD FOR ELECTRIFIED AIRCRAFT
Document Type and Number:
WIPO Patent Application WO/2015/146608
Kind Code:
A1
Abstract:
[Problem] To provide electrified aircraft such that the path angle and rate of descent can be controlled independently of speed and with high response by operating the drag of a propulsion drive system whereby electric power generated during descent or in an updraft can be maximized safely in various flying states, and to provide a regenerated electric power control method for the electrified aircraft.
[Solution] This electrified aircraft is provided with: a propeller for propulsion; an electric drive motor for rotatably driving the propeller and generating electricity by the rotation of the propeller; and an estimation unit that estimates the drag of the propeller or a fan on the basis of a propulsion system parameter of the electric drive motor.
