    • A device for improving performance of an aircraft with a propeller includes a constant torque blade setting device that slaves, automatically and independently, blade setting angles, respectively associated with blades of the propeller, to a constant reference control moment predetermined, for a desired propeller thrust value. The blade setting angles are intended to be applied on each blade such that torsion aerodynamic moments applied on blades stay roughly equal to the reference control moment regardless of the angular position of blades in the propeller plane. A corresponding method for improving performance of an aircraft includes the use of the constant torque blade setting device to slave blade setting angles to a constant reference control moment.
    • 用于提高具有螺旋桨的飞行器性能的装置包括恒定力矩叶片设定装置,其自动且独立地将分别与螺旋桨的叶片相关联的叶片设定角度固定为预定的预定螺旋桨推力的恒定参考控制力矩 值。 叶片设定角度旨在施加在每个叶片上,使得施加在叶片上的扭转空气动力学力矩大致等于参考控制力矩,而与螺旋桨平面中的叶片的角位置无关。 用于提高飞行器性能的相应方法包括使用恒转矩叶片设定装置将从动叶片设定角度用于恒定的参考控制力矩。
