The invention relates to a coaxial double-rotor aircraft with asymmetric rotors and a control method thereof. The aircraft comprises an aircraft body, a first driving motor arranged above the aircraftbody, an upper rotor wing arranged above the first driving motor, a second driving motor arranged below the aircraft body and a lower rotor wing arranged below the second driving motor. The upper rotor comprises a first motor connecting base connected with a rotating shaft of the first driving motor, an upper rotor main blade and an upper rotor auxiliary blade, wherein the upper rotor main bladeand the upper rotor auxiliary blade are asymmetrically arranged on the two sides of the first motor connecting base. The lower rotor wing comprises a second motor connecting seat connected with a rotating shaft of the second driving motor, and a lower rotor wing main blade and a lower rotor wing auxiliary blade which are asymmetrically arranged on the two sides of the second motor connecting seat.According to the coaxial double-rotor aircraft and the control method thereof, pitching, rolling and yawing full-degree-of-freedom attitude controllable flight can be realized without a rotor tiltingmechanism and a variable-pitch mechanism, so that the mechanical structure of the aircraft is greatly simplified, the part manufacturing, assembling and maintaining difficulty is reduced, and the operation reliability is improved.
本发明涉及一种具有非对称旋翼的共轴双旋翼飞行器及其操控方法。该飞行器包括机身、安装在机身上方的驱动电机一、安装在驱动电机一上方的上旋翼、安装在机身下方的驱动电机二和安装在驱动电机二下方的下旋翼。上旋翼包括与驱动电机一的转轴相连的电机连接座一以及非对称设置在电机连接座一两侧的上旋翼主叶片与上旋翼副叶片。下旋翼包括与驱动电机二的转轴相连的电机连接座二以及非对称设置在电机连接座二两侧的下旋翼主叶片与下旋翼副叶片。该共轴双旋翼飞行器及其操控方法,无需旋翼倾转机构和变距机构即可实现俯仰、横滚、偏航全自由度的姿态可控飞行,极大地简化了飞行器机械结构,降低了部件制造、装配以及维护难度,提升了运行的可靠性。
