Abstract: A reconfigurable unmanned aircraft system is disclosed. A system and method for configuring a reconfigurable unmanned aircraft and system and method for operation and management of a reconfigurable unmanned aircraft in an airspace are also disclosed. The aircraft is selectively reconfigurable to modify flight characteristics. The aircraft comprises a set of rotors. The position of at least one rotor relative to the base can be modified by at least one of translation of the rotor relative to the boom, pivoting of the boom relative to the base, and translation of the boom relative to the base; so that flight characteristics can be modified by configuration of position of at least one rotor relative to the base. A method of configuring an aircraft having a set of rotors on a mission to carry a payload comprises the steps of determining properties of the payload including at least mass properties, determining the manner in which the payload will be coupled to the aircraft, determining configuration for each of the rotors in the set of rotors at least partially in consideration of the properties of the payload, and positioning the set of rotors in the configuration for the aircraft to perform the mission.

Abstract: The present invention provides an unmanned aerial vehicle that can maintain stability by changing positions of rotating rotors when one of the rotating rotors malfunctions, and a method for controlling stability of the unmanned aerial vehicle. The unmanned aerial vehicle includes: a main body; a plurality of support bars that are arranged while forming an angle with each other along a circumferential direction of the main body and extended to an outer side from the main body; a plurality of rotating rotors that are respectively provided to the support bars and generate thrust; motors that are respectively connected to the rotating rotors to drive the rotating rotors; drivers that change positions of the respective rotating rotors along the circumferential direction of the main body by moving the support bars with respect to the main body; and a controller that maintains horizontal stability of the main body by controlling the drivers.

Abstract: A propeller alignment device is described. The propeller alignment device can include a second retainer attached to a propeller and a motor. The propeller alignment device can also include a first retainer that does not rotate, but that is aligned with the second retainer. The first retainer can include two or more magnets oppositely orientated relative to each other. The second retainer can also include two or more magnets oppositely orientated relative to each other. As the second retainer rotates relative to the first retainer, the magnets may alternatingly align with each other. In the absence of a current applied to the motor, the magnets may magnetically bias the second retainer into a predetermined orientation relative to the first retainer. The predetermined orientation can be predetermined to correspond to an alignment of the propeller that is desirable (e.g., that minimizes aerodynamic drag on the propeller).

Abstract: This disclosure describes a configuration of an unmanned aerial vehicle (UAV) that will facilitate extended flight duration. The UAV may have any number of lifting motors. For example, the UAV may include four lifting motors (also known as a quad-copter), eight lifting motors (octo-copter), etc. Likewise, to improve the efficiency of horizontal flight, the UAV also includes a pushing motor and propeller assembly that is oriented at approximately ninety degrees to one or more of the lifting motors. When the UAV is moving horizontally, the pushing motor may be engaged and the pushing propeller will aid in the horizontal propulsion of the UAV.

Abstract: A light unmanned vertical take-off aircraft includes at least two fixed coplanar propulsion devices and at least one wing providing the lift for the drone. The coplanar propulsion devices and the wing are each laid out on the frame of the drone so that the plane of the profile chord line of the wing is substantially parallel to the plane defined by the two coplanar propulsion devices. The wing is pivotingly mobile relative to the frame along an axis parallel to the pitch axis of the drone. Also a method is provided for controlling orientation of a wing of a light unmanned vertical take-off aircraft as described here above. The method includes controlling an orientation of a wing as a function of at least one flight parameter of the aircraft.

Abstract: A tether compensated unmanned aerial vehicle (UAV) is described. In one embodiment, the UAV includes a winch with a tether to lower an item from the UAV for delivery, a flight controller to control a flight path of the UAV, a tether compensation mechanism through which the tether extends, at least one sensor to identify movement in the tether, and a tether response controller. Based on movement identified in the tether, the tether response controller may determine a complementary response and direct the tether compensation mechanism to brace the tether against the movement. Thus, the tether compensation mechanism may stabilize sway or movement in the tether by moving against the sway or movement, which may help prevent the tether from undesirable swinging when lowering the item from the UAV for delivery, for example, or at other times.
