A rotor-wing assembly includes a motor, a propeller, and a connection assembly connecting the propeller to the motor. The motor includes a rotating portion. The connection assembly includes a locking member and a reinforcing member arranged between the propeller and the motor. The locking member locks the propeller to the rotating portion. A first end of the reinforcing member is mounted at the rotating portion. A second end of the reinforcing member opposite to the first end is engaged with the locking member, to reinforce the locking member to lock the propeller to the rotating portion.

Embodiments of the present disclosure provide systems and methods to eliminate (or filter) drift for dynamics model based localization of multirotors. The dynamics equations require drag modelling, which is dependent on velocity, to generate vehicles' acceleration along the body axis. The present disclosure considers the drag contribution, at velocity level, as a low frequency component. Incorrect or nonmodelling of this low frequency component leads to drift at velocity level. This drift can then be removed through a high pass filter to obtain drift free velocity data for pose estimation and better localization thereof.

[Object] To provide a rotary wing aircraft capable of self-leveling and ensuring a stable landing state. [Solution] The rotary wing aircraft according to the present disclosure comprises a plurality of rotary blades, an arm part for supporting the plurality of rotary blades, a mounting part for mounting an object, and a connecting part for connecting the mounting part to the arm part in a state where the mounting part is movable within a predetermined range. The position of the connecting part of the rotary wing aircraft of the present disclosure is above the center of gravity of the arm part. Thereby, self-leveling is made possible and a stable landing state can be ensured.
