Abstract: This disclosure describes a multi-wing manned or unmanned compact personal vertical takeoff and landing aircraft, comprising the integration of: a plurality of parallel wings forming a boxed planform multi-wing assembly with no dynamic airfoil control surfaces, statically affixed to a co-planar adjacent counter-rotating quad-rotor air propulsion system; and a fuselage free to rotate under servo control about an axial shaft, permitting dynamic orientation manipulation. The vehicle described herein achieves: high maneuverability and attitude orientation control incumbent upon the ratio of power delivered to the quad-rotors; area constrained and enhanced wind gust insensitive VTOL capability; high fuel efficient non-hover aerodynamic flight capability; high external field-of-view optical visibility from the fuselage interior; convenient fuselage interior accessibility; and enhanced net pitching moment of inertia about the multi-wing assembly net aerodynamic center, permitting rapid transitioning to and from aerodynamic flight orientation.

Abstract: A method and system for assessing a situation using an unmanned vehicle is disclosed. An unmanned vehicle receives a transmission indicating a situation at a designated location, and then navigates to the designated location. The unmanned vehicle may reach the designated location via air or ground travel, or a combination thereof. The unmanned vehicle receives signals from a first subset of sensors indicating information concerning an environment at the designated location and from a second subset of sensors indicating information concerning one or more objects associated with the situation. The unmanned vehicle then sends one or more transmissions based on the received signals, facilitating rapid determination of the situation.

Abstract: Described herein are methods and systems for detecting and correcting errors when picking up and lowering a payload coupled to a tether of a winch system arranged on an unmanned aerial vehicle (UAV). For example, the winch system may include a motor for winding and unwinding the tether from a spool, and the UAV's control system may control the motor to lower the tether and monitor an electric current supplied to the motor to determine whether a payload has detached from the tether. This process of lowering the tether and monitoring the motor current may be repeated up to a predetermined number of times, at which point the control system may operate the motor to detach the tether from the spool, leaving both the tether and the payload behind.

Abstract: Proposed method and device could be applied as controlling system facilitating the maneuverability and stabilization parameters of UAV, as well as various flight objects and small satellites. The aim of the invention is to reduce the occurrences of imbalances of UAV in strong wind or atmospheric turbulence situations and simultaneously rehabilitation of maneuverability and stabilization parameters without increasing flight speed.Thus, in order to upgrade the above mentioned parameters of UAV along with the gyroscopic momentum compensation it's necessary to increasing of the kinetic moment by means of gyroscope.This is achieved by installing the gyroscopes oppose to the propeller taking into account the gravity center of UAV (with rear-mounted propeller gyroscope should be installed in front sector), the direction of rotation of the gyro rotor is directed against the rotation of the propeller (the axis of the gyro rotor and propeller are in straight line); availing high kinetic momentum the devise becomes less subjected to the effects of the wind and turbulence; changing of the flight trajectory performed by moving axis of the gyroscope (stabilization and moments motors) and reductor, that fixed on moving shaft of the rotary frame, and the gyroscope is installed in a device to perform coincidence of the gyroscopic moments with the direction of the rotation of UAV. Coincidence of the directions of gyroscopic moments with the moments of the elevator and rudder increases the UAVs maneuverability. Stabilization and modification of the angular position of the UAV relative to the longitudinal roll axis is performed by increasing or decreasing of rotations of the gyro rotor with adjustable inertial moment.

Abstract: An aerial vehicle is includes a wing, first and second rotors, and a movement sensor. The first and second multicopter rotors are rotatably coupled to the wing, the first multicopter rotor is rotatable relative to the wing about a first lateral axis, and the second multicopter rotor is rotatable relative to the wing about a second lateral axis. Each multicopter rotor is coupled to each other multicopter rotor, wherein the multicopter rotors are restricted to collective synchronous rotation relative to the wing between a multicopter configuration and a fixed-wing configuration. The movement sensor is coupled to the multicopter rotors, wherein the movement sensor is positioned to rotate relative to the wing when the multicopter rotors rotate relative to the wing between the multicopter and fixed-wing configurations.
