摘要： Disclosed is an electrically powered, reaction-drive type rotorcraft. Thrust generators on the outer portion of each rotor blade cause the rotors to spin and generate lift, and additionally, may be controlled to produce variable amounts of thrust as the rotor blades rotate through different sectors around a generally non-rotating fuselage such that net lateral forces are produced to control the position and velocity of the vehicle. The rotorcraft may also employ aerodynamic surfaces on each rotor blade whose parts or entire structure can be moved to produce net lateral and vertical forces for control of position and velocity of the vehicle. The rotorcraft, which may be operationally carbon-neutral, stores its electrical energy in batteries and other optional energy storage methods, and may harvest solar energy using arrays of photovoltaic cells disposed on its upper surfaces. Vehicle sizes may range from small Uncrewed Air vehicle Systems to large crewed aircraft.

摘要： An exemplary method includes controlling a rotation rate of a rotor in a vehicle, detecting that an electric motor system is electrically energized and rotating the rotor at least at a minimum rotation rate that is greater than zero in response to the electric motor system being electrically energized. The rotor may be rotated at least at the minimum rotation rate when the electric motor system is energized and the motor is turned-off.

摘要： An aircraft is provided including an airframe, an extending tail, a counter-rotating, coaxial main rotor assembly having an upper rotor assembly and a lower rotor assembly, and a translational thrust system including a propeller positioned at the extending tail. The translational thrust system is configured to provide translational thrust to the airframe when the aircraft is in a non-autorotation state and to generate power when in an autorotation state. A gearbox interconnects the propeller and the main rotor assembly to drive the main rotor assembly and the translational thrust system in the non-autorotation state. When the aircraft is in autorotation, the power generated by the propeller drives rotation of the main rotor assembly via the gearbox.

摘要： A rotating apparatus includes a rotating assembly and a position-limiting assembly. The rotating assembly includes a driving unit and at least one rotating component. The driving unit is adapted to drive the rotating component to rotate with a first axis. The position-limiting assembly includes a position-limiting component, at least one first column, and a buckling component. The position-limiting assembly is disposed on the rotating assembly and is adapted to limit a position of the rotating component. The first column is connected to the position-limiting component. The position-limiting component is located between the rotating component and the buckling component and is able to move along the first axis. The buckling component is movably disposed on the position-limiting component and has at least one buckling portion. The buckling portion is adapted to be buckled to the first column or move away from the first column.

摘要： The present invention provides a power device generating greater propelling force and finds that traditional power devices do not include all propelling forces based on the fundamental core propelling force source problem. External pressure is guided to the traditional power devices since the inner speed is higher the outer speed, power consumption for overcoming fluid resistance is high, and mutual contradiction results are obtained. The unique difference between the present invention and general common sense lies in opposite fluid pressure directions; inner fluid channels and outer fluid channels with higher flow speeds are formed to generate pressure differences which guides the fluid pressure to the outside and serve as propelling force, and thus the present invention creatively finds three propelling force sources, two lifting force or propelling force sources of helicopters or airplanes driven by propellers and two propelling force sources for sufficient burning of fuel in combustion chambers of engines.
