Title:
CYCLOIDAL ROTOR HAVING AN ELLIPTICAL BLADE TRAJECTORY AND METHOD OF CONTROLLING AN AIRCRAFT USING A CYCLOIDAL ROTOR
Document Type and Number:
WIPO Patent Application WO/2019/139559
Kind Code:
A1
Abstract:
The invention relates to aviation technology, more particularly to aircraft construction, and even more particularly to a cycloidal rotor that can be used to generate lift and to control an aircraft. The present cycloidal rotor comprises a disk (1) having arms (3) with blades (5) fastened thereto, said blades being capable of following a non-circular trajectory with the aid of a drive and a control system. The arms (3) are capable of rotating in a direction opposite to the direction of rotation of the disk (1). One end of each arm (3) constitutes the axis of rotation (4) of the arm, and the opposite end of the arm (3) has a blade (5) attached thereto. The ends of the arms that are not attached at the axis of rotation are capable of creating an elliptical trajectory. The control system comprises a mechanism for tilting the elliptical trajectory and a mechanism for controlling the angle of attack of a blade, which are connected to the drive. According to the present method, combining the circular trajectory of the axis of an arm (3) relative to the axis of rotation of the body of the disk (1) and the circular trajectory of the axis of a blade (5) relative to the axis of rotation of an arm (3) results in an elliptical trajectory (7) of the axis of a blade relative to the axis of rotation of the disk. The technical result of the invention is that of increasing the efficiency of the cycloidal rotor by changing the circular trajectory of a blade into an elliptical trajectory.
