The cycloidal propeller aircraft comprises a propeller, a fuselage, a cycloidal propeller, an empennage and an undercarriage, the cycloidal propeller comprises a main shaft, a pull rod, a blade shaft and blades, the main shaft can drive the pull rod, the blade shaft and the blades to rotate around the axis of the main shaft, the pull rod is fixedly connected with the main shaft, the blade shaft can freely rotate relative to the pull rod, and the pull rod supports the blade shaft; the paddle shaft is fixedly connected with the paddles, the number of the paddles is not less than two, each paddle is provided with an independent transmission system, each transmission system drives the corresponding single paddle to rotate around the axis of the paddle shaft, and the rotation of all the paddles around the axis of the paddle shaft is not correlated; the cycloidal propeller aircraft is simple in structure, the propeller blades serve as fixed wings when flying forwards normally, and dead weight is avoided; in the transition state of takeoff and landing, the cycloidal propellers are gradually accelerated and decelerated, and proper lift force is provided.
本发明涉及一种摆线桨飞行器,包括螺旋桨、机身、摆线桨、尾翼和起落架,所述摆线桨包括主轴、拉杆、桨叶轴和桨叶,主轴能带动拉杆、桨叶轴和桨叶围绕主轴轴线旋转,拉杆与主轴固定连接,桨叶轴相对拉杆可自由转动,拉杆支撑桨叶轴,桨叶轴和桨叶固定连接,桨叶的个数不少于两个,每个桨叶都有一个独立的传动系统,每个传动系统带动相应的单个桨叶围绕所述桨叶轴的轴线旋转,所有桨叶围绕所述桨叶轴轴线的旋转互无关联;本发明的摆线桨飞行器结构简单,桨叶在正常前飞时作为固定翼,无死重;在起飞降落的过渡状态摆线桨逐渐加减速,提供合适的升力。
