摘要： A multirotor aircraft that includes a chassis, at least three engines that are equipped with propellers, and one or more axial free wings that are connected to the chassis by axial connections. The leading edges of the one or more axial free wings are designed to face constantly same direction when the multirotor flying, and the attack angles of the one or more axial free wings are designed to be changed relatively to the chassis due to flow of air over the one or more axial free wings.

摘要： A multi-rotor aircraft includes a fuselage, a propulsion engine coupled to the fuselage that generates thrust to propel the aircraft along a first vector during forward flight, and rotors coupled to the fuselage, each rotor comprising blades, each rotor coupled to a motor, and each motor configured to supply power to and draw power from the coupled rotor. The aircraft includes a flight control system configured to control the motors coupled to the rotors in a power managed regime in which a net electrical power, consisting of a sum of the power being supplied to or drawn from each rotor by its motor, is maintained within a range determined by a feedback control system of the flight control system. The flight control system can also be leveraged to adjust rotor control inputs to modify at least one of thrust, roll, pitch, or yaw of the multi-rotor aircraft.

摘要： A method of assembling a delivery payload assembly configured to be deployed from an aircraft and travel along a flight path to a predetermined landing destination includes attaching a tail-kit assembly to a first end of a payload, the tail-kit assembly including a rotor blade assembly including a plurality of rotor blades having a central axis of rotation, and a flight control and navigation system configured to control a collective pitch angle of each of the plurality of rotor blades of the rotor blade assembly, configured to control an axial thrust force of the rotor blade assembly, the axial thrust force being at an angle with respect to the central axis of rotation of the rotor blade assembly, and configured to navigate the delivery payload assembly along the flight path to the predetermined landing destination. The method further includes removing the tail-kit assembly from the payload after the payload is delivered to the predetermined landing destination.

摘要： A method of controlling an unmanned aerial vehicle includes receiving a first signal including information relating to a payload of the unmanned aerial vehicle, retrieving a predetermined value from a memory of the unmanned aerial vehicle based on the information of the first signal, and generating a second signal for changing a configuration of an arm of the unmanned aerial vehicle to change a distance of at least one of a plurality of propulsion units of the unmanned aerial vehicle corresponding to the arm from a reference point on a central body of the unmanned aerial vehicle based on the predetermined value.

摘要： A coupled battery and motor controller thermal management system is disclosed. In various embodiments, a motor controller and a heat sink are coupled thermally to a battery. At least a portion of waste heat generated by the motor controller is transferred to the thermal mass of the battery during at least a first mode of operation in which a relatively low amount of ambient air flows through the heat sink.

摘要： A battery powered helicopter uses one or more torque arms as the power source directly driving the main rotor blades, causing them to rotate. The helicopter does not require a combustion engine, a clutch, a reducer, a tail driver, a tail boom, a tail rotor, or a fuel supply system. The output shaft of the high-energy motor is coaxial with the main rotor shaft. The centrifugal force of one or more motor(s) is negligible or minimized. The torque arm assembly includes a plurality of torque arms. Each of the torque arms of the plurality of torque arms includes a propeller and a driving system.

摘要： A helicopter uses electric propeller torque arm as power source directly driving main rotor to rotate. The helicopter may be battery powered. The helicopter may be without an engine, a clutch, a reducer, a tail driver, a tail boom, a tail rotor and a fuel supply system. The main design goal is to have the output shaft of the high-energy motor being coaxial with the main rotor shaft or having output shafts of a plurality of motors as close as possible to the main rotor shaft. The centrifugal force of the motor(s) is negligible or minimized. The torque arm assembly includes a plurality of torque arms. Each of the torque arm of the plurality of torque arms includes a propeller and a driving system. In the case of a malfunction, the helicopter's main rotor will spin like a maple leaf and will facilitate the spin autorotation landing.

摘要： A helicopter has a helicopter body with a longitudinal axis and a rotor head which is driven via the rotor drive axis. The helicopter further has at least two rotor blades held via one rotor blade shaft each. In order to permit higher speeds, a rotor bearing axis of the rotor blade shafts is adjustable perpendicular to a direction of extent of the rotor bearing axis in relation to the rotor drive axis.
