Title:
ブラシレス電気モータを用いて航空機タービンエンジンプロペラのブレードの迎え角を変更するシステム
Document Type and Number:
Japanese Patent JP2013508212
Kind Code:
A
Abstract:
A system for varying an angle of attack of blades of an aircraft turbine engine propeller, including an axial flow brushless motor including a stator including coils, and a rotor including permanent magnets. The rotor is mounted axially movable between a locked position in which it is secured in rotation with a rotary hub of the propeller, and an unlocked position in which its rotation relative to the hub along the axis of rotation of the propeller causes a variation of the angle of attack of the blades via a mechanical connecting mechanism.
