An unmanned aerial vehicle (UAV) (100). The UAV (100) comprises a central body (105). The UAV (100) also comprises a plurality of landing gears (120) that are extendable from and movable relative to the central body (105). The plurality of landing gears (120) are configured to transform between (1) a flight configuration wherein the landing gears (120) are extending laterally away from the central body (105) and not in contact with a surface below the central body (105), and (2) a surface configuration wherein the landing gears (120) are extending towards the surface below the central body (105). Additionally, when the landing gears (120) are in the surface configuration, the landing gears (120) are configured to (a) support a weight of the central body (105) on said surface, and (b) transport the UAV (100) over said surface by moving one or more landing gears (120) relative to the surface. A method of operating the unmanned aerial vehicle (UAV) (100) is also provided.

One example embodiment includes a vertical takeoff and landing (VTOL) unmanned aerial vehicle (UAV) (12). The VTOL UAV includes a flight control system configured to provide avionic control of the VTOL UAV in a hover mode and in a level-flight mode. The VTOL UAV also includes a body (18) encapsulating an engine and the flight control system. The VTOL UAV further includes a rotor disk (14) coupled to the engine and configured to provide vertical thrust and cyclic pitch control in the hover mode and to provide horizontal thrust for flight during the level-flight mode.
摘要:
The universal vehicle system is designed with a lifting body which is composed of a plurality of interconnected modules which are configured to form an aerodynamically viable contour of the lifting body which including a front central module, a rear module, and thrust vectoring modules displaceably connected to the front central module and operatively coupled to respective propulsive mechanisms. The thrust vectoring modules are controlled for dynamical displacement relative to the lifting body (in tilting and/or translating fashion) to direct and actuate the propulsive mechanism(s) as needed for safe and stable operation in various modes of operation and transitioning therebetween in air, water and terrain environments.

An improved vehicle with superior performance and reliability. The vehicle, such as an unmanned aerial vehicle, is capable of vertical takeoff and landing, uses three swashless, variable-pitch vertical lift main rotors with a yaw tail rotor system. Two rear main rotors are optionally tiltrotors, which pivot to increase forward speed without the increased coefficient of drag inherent in tilting the entire vehicle. The three main rotors are positioned in an equilateral triangular configuration, improving balance, increasing load-bearing strength, and making it more compact in size. Movements are controlled through changes in pitch of the rotors, allowing the motors to maintain constant governed rotations per minute, maximizing drivetrain efficiency. Vehicle configurations disclosed herein allow for smaller vehicle size with greater performance than prior art vehicles.

摘要:
Modular nacelles to provide vertical takeoff and landing (VTOL) capabilities to fixed-wing aerial vehicles, and associated systems and methods are disclosed. A representative system includes a nacelle, a power source carried by the nacelle, and multiple VTOL rotors carried by the nacelle and coupled to the power source. The system can further include an attachment system carried by the nacelle and configured to releasably attach the nacelle to an aircraft wing.
摘要:
A VTOL aircraft includes at least one puller rotor and at least one pusher rotor. The VTOL aircraft, for example, may include three puller rotors and one pusher rotor. The combination of static puller and pusher rotors allows the rotors to remain in a fixed orientation (i.e., no moving mechanical axes are required) relative to the wings and fuselage of the VTOL aircraft, while being able to transition the aircraft from a substantially vertical flight path to a substantially horizontal flight path.
