摘要： A system includes an electric motor. A drive shaft is connected to be driven by the electric motor. A propulsor is connected to be driven by the shaft. The propulsor is configured to pivot to a first orientation configured to produce lift when the motor rotates the shaft in a first direction, and to pivot to a second orientation configured to produce thrust when the motor rotates the shaft in a second direction that is opposite of the first direction.

摘要： A compound vertical takeoff and landing aircraft includes a fuselage with a modular payload configuration for passenger, cargo, or medical transport functions; contra-rotating main rotors mounted on an upper side of the fuselage and driven by at least one motor; and a plurality of tiltable thrusters mounted respectively at a forward section and at an aft section of the fuselage, each tiltable thruster being powered by one or more separate motors. The motors driving the contra-rotating main rotors and the tiltable thrusters may all be electric. The tiltable thrusters may be ducted or unducted and may each be provided with one or more control surfaces at an aft end. Battery modules may be located underneath a floor of the fuselage and may be arranged in one or more groups of batteries so as to so as to facilitate removal and replacement of the batteries.

摘要： An electrically-powered VTOL aircraft has a fuselage with a cabin flexibly connected to a powerplane assembly that includes a plurality of electrically-powered rotors and booms. The powerplane assembly can pitch and roll relative to and independently of the cabin, thereby generating efficient fore, aft and lateral thrust while the cabin attitude remains unchanged. This provides a stable passenger experience and enhanced performance and controllability with reduced cost and complexity. In some embodiments, the fuselage is vertically elongated and the powerplane assembly mounts above the fuselage such that a person may walk beneath the rotors completely erect. A VTOL docking station is also disclosed that is configured to allow the aircraft to land without the use of landing gear. The docking station also includes electrical components configured to automatically provide charging to the aircraft when the aircraft is docked with the docking station.

摘要： The aircraft can include: an airframe, a tilt mechanism, a payload housing, and can optionally include an impact attenuator, a set of ground support members (e.g., struts), a set of power sources, and a set of control elements. The airframe can include: a set of rotors and a set of support members. By utilizing a larger rotor blade area (and/or larger rotor disc area) and adjusting the blade pitch and RPM, the rotors can augment the lift generated by the aerodynamic profile of the aircraft in the forward flight mode in addition to providing forward thrust. Variants generating lift with the rotors can reduce or eliminate additional control surfaces (e.g., wing flaps, ailerons, ruddervators, elevators, rudder, etc.) on the aircraft since the thrust and motor torque is controllable (thereby indirectly controlling lift) at each rotor, thereby enabling pitch, yaw, and/or roll control during forward flight.

摘要： A vertical takeoff and landing (VTOL) vehicle that includes a flight controller and a rotor. During a vertical landing state, during which the VTOL vehicle is performing a vertical landing, the flight controller decides whether to switch from the vertical landing state to a self adjusting state and in the event it is decided to do so, the flight controller switches from the vertical landing state to the self adjusting state. During the self adjusting state, the flight controller generates a control signal for a rotor where the control signal causes: (1) the rotor to rotate during the self adjusting state and (2) the VTOL vehicle to stay in place during the self adjusting state, such that an occupant is able to enter or exit the VTOL vehicle during the self adjusting state.

摘要： Spring-integrated rotors are disclosed. A disclosed example apparatus includes a bracket defining a first rotational axis and coupled to a motor for rotating the bracket about the first rotational axis, a pivot body defining a second rotational axis extending along a direction different than the first rotational axis, the pivot body coupled to the bracket for rotation about the second rotational axis, and at least one spring device positioned at the bracket, the at least one spring device urging the pivot body toward a central position when the bracket is rotating.

摘要： A delivery rotary-wing aircraft has a plurality of rotary wings, a central portion to which a plurality of arms for supporting the rotary wings are connected, a first mounting portion for loading a package, a second mounting portion which is located on the opposite side to the first mounting portion as viewed from the central portion, a first supporting member for coupling the first mounting portion with the central portion, and a connection portion between the central portion and the first supporting member. The center point of lift occurring in the rotary-wing aircraft with the rotation of the plurality of rotary wings and the center point of gravity of the rotary-wing aircraft coincide with the center point of the connection portion. The first supporting member is equipped with an adjustment mechanism for vertically downwardly extending the length of the first supporting member.

摘要： A method for the flying of a vertical take-off and landing aircraft which uses fixed rotors for both VTOL and forward flight operations. The rotors form a synthetic wing and are positioned to achieve a high span efficiency. The rotors are positioned to even out the lift across the span of the synthetic wing. The synthetic wing may also have narrow front and rear airfoils which may provide structural support as well as providing lift during forward flight, or may have a single center wing. The wing rotors are tilted forward and provide some forward propulsion during horizontal flight.

摘要： A portion of a vehicle includes occupant zones in rows. First and second of the occupant zones are adjacent rows and the portion of the vehicle further includes access points arranged for user ingress into the vehicle. Each access point is located positionally asymmetric with all opposing access points of the portion. Further the access points include first and second access points located about the portion such that the direction of ingress through the first access point is substantially opposed to the direction of ingress through the second. The first occupant zone is the nearest to the first access point and the second occupant zone is the nearest to the second access point. The first occupant zone is to be preferentially accessed by user ingress from the first access point, and the second occupant zone is to be preferentially accessed by user ingress from the second access point.
