A vertical takeoff and landing (VTOL) unmanned aircraft system (UAS) may be uniquely capable of VTOL via a folded wing design while also configured for powered flight as the wings are extended. In a powered flight regime with wings extended, the VTOL UAS may maintain controlled powered flight as a twin pusher canard design. In a zero airspeed (or near zero airspeed) nose up attitude in a VTOL flight regime with the wings folded, the unmanned aircraft system may maintain controlled flight using main engine thrust as well as vectored thrust as a vertical takeoff and landing aircraft. An airborne transition from VTOL flight regime to powered flight and vice versa may allow the VTOL UAS continuous controlled flight in each regime.

A transformable Unmanned Aerial Vehicle (UAV), can operate as a coplanar hexacopter or as an omnidirectional multirotor based on different operation modes. The UAV has 100% force efficiency for launching or landing tasks in the coplanar mode. In the omnidirectional mode, the UAV is fully actuated in the air for agile mobility in six degrees of freedom (DOFs). Models and control design are developed to characterize the motion of the transformable UAV. Simulation results are presented to validate the transformable UAV design and the enhanced UAV performance, compared with a fixed structure.

The operational efficiency of a rotorcraft in cruising. The rotary wing aircraft, according to the present disclosure, has a main body and a plurality of motors provided in the main body for rotating each of the rotors, which are parallel to a reference plane. When the main body is inclined with respect to one direction of travel and flying in the direction of travel, the rotational speed of each of the plurality of motors is approximately the same.

A battery powered octocopter drone with a protective frame. An articulating arm is mounted to the drone with a battery powered chain saw positioned along the end of the articulating arm. The chainsaw allows for the trimming of remote trees and bushes previously only accessible by a ladder or bucket lift. The drone is adjustable forward/aft to compensate for the center of gravity. The drone includes a remote control receiver, telemetry and an antenna allowing an operator to control all aspects of the drone from a remote position.

An aeronautical vehicle performs horizontal flight and/or vertical flight, and has a fuselage, a wing assembly having a first wing part and a second wing part rigidly coupled to one another, a rotor assembly, a horizontal thruster, and an attitude control system. The wing assembly is arranged rotatably with respect to the fuselage to rotate about a vertical pivot axis between a stow position and an active position. The rotor assembly includes two vertical thrust rotors arranged on a rotor support rotatably with respect to the fuselage to rotate the rotor assembly between a stow position and an active position. In a horizontal flight mode the wing assembly is in the active position and the rotor assembly is in the stow position, and in a vertical flight mode the wing assembly is in the stow position and the rotor assembly is in the active position.

An apparatus includes: a mechanical interface configured to couple an object to a frame of an aircraft; one or more processors; and a computer readable medium storing instructions that, when executed by the one or more processors, cause the apparatus to perform functions that include: detecting a control input provided to an actuator of the aircraft and/or an output of a sensor that indicates a state of the actuator; determining, based on the control input provided to the actuator and/or the output of the sensor, a procedure for moving the object relative to the frame; and using the mechanical interface to perform the procedure.
