MULTI-ROTOR SYSTEM AND RELATED SYSTEM AND AIR VEHICLE

The present application discloses a multi-rotor system comprising at least two rotors rotatable about a common axis wherein the outer radius of the blades of each of the at least two rotors is slightly shorter than the inner radius of the blades of an adjacent rotor having the longer radius, and wherein the at least two rotors are rotatable at different angular velocities relative to each other, to rotate the rotor blade tips of the at least two rotors at substantially the same tangential speed. The application also discloses a system comprising at least two multi-rotor systems arranged axially relative to each other and an air vehicle adapted to perform vertical take-off and landing. 本申请公开了一种多转子系统，包括能围绕共同轴线旋转的至少两个转子，其中，至少两个转子中的每个转子的叶片的外半径略短于具有较长半径的相邻转子的叶片的内半径，并且其中，至少两个转子能以相对于彼此不同的角速度旋转，以使至少两个转子的转子叶片尖端以基本相同的切向速度旋转。本申请还公开了一种包括相对于彼此轴向布置的至少两个多转子系统的系统以及一种适于执行垂直起降的空中运载工具。
