A drone docking port (DDP) preferably mounted on a pole and having an openable and closable convertible top (CT), a docking plate having integrated battery wired or wireless recharging pads, and a control module. The control module (CM) is adapted to preferably autonomously control all functions of the DDP including actuation of the CT and relay of video, audio, and flight control information between the CM and a central monitoring center and/or emergency personnel. The DDP is preferable positioned in close proximity to an intended monitoring site. When the CT is in an open position, a drone may initiate flight from the DDP and when a drone flight is completed and a drone has re-docked therein, the CT may be closed to protect the drone docked therein from external weather. The DDP may further include Electro-Optical/Infra-Red (EO/IR) cameras and sensors to detect disruptive or other predetermined behavior.

The present disclosure provides a mounting mechanism of a UAV. The mounting mechanism includes a rotating part rotatably connected with a center frame and connected with a landing gear; and a driving part driving the rotating part to rotate when a carrier for carrying a payload rotates.

An Electric Vertical Take-off and Landing (EVTOL) Passenger Air Vehicle (PAV) using a plurality of electric motors positioned concentrically about the passenger compartment and utilizing ducted turbines to produce thrust allowing the vehicle to take off and land vertically and fly without the use of aerodynamic wings. Utilizes a plurality of independent electric battery powered motors providing sufficient thrust to ensure the vehicle can hover and complete a safe landing despite a loss of thrust from any two adjacent motors and up to half of the motors, if non-adjacent, by utilizing redundant onboard flight control systems to vary motor torque as need to maintain steady, controlled flight. Design utilizes a pivoting seat for passenger comfort as well as shock mounting of the seat for safety. Ingress and egress are facilitated by integrated folding air stairs. The turbine fairing is designed to be rapidly manufactured as two parts, as upper and lower shells, using a composite forging process.

A wheel well fairing for reducing drag on an aircraft fuselage configured with an open wheel well for stowing landing gear of the aircraft. The wheel well fairing includes a Coanda fairing having a convex-shaped lower portion and an upper portion. The upper portion is configured for positioning adjacent an interior vertically-orientated sidewall of the wheel well, and the convex-shaped lower portion has a bottom surface configured to extend substantially parallel to and positioned adjacent with an outer hull surface of the fuselage. The convex-shaped lower portion is curved inwardly within the wheel well between the upper portion and bottom surface. The Coanda fairing is positioned at an aft portion of the wheel well to redirect airflow out of the wheel well in a rearward direction along the bottom hull surface of the fuselage.

A landing gear system for an aircraft is presented. The landing gear system comprises a composite flex beam having through-thickness stitching and a curvature having a radius greater than 5 inches; and a trunnion connected to the composite flex beam and offset from a neutral surface of the composite flex beam.

A hybrid power tri-propeller helicopter apparatus for efficient and quiet flying includes a helicopter body, a cockpit portion, an engine portion, a tail boom portion, a gas motor, a generator, a battery pack, and an electric nose motor. A nose propeller and a lift propeller support are coupled to the helicopter body. A pair of electric lift motors is coupled to the lift propeller support and is in operational communication with the battery pack. A pair of lift propellers is coupled to the pair of lift motors. A tail fin and a pair of horizontal rear stabilizer fins are coupled to the tail boom portion. A pair of front stabilizer fins is coupled to the cockpit portion. A plurality of controls is coupled to the cockpit portion and is in operational communication with the nose motor, the pair of lift motors, and the pair of rear stabilizer fins.

A fixed-wing VTOL hybrid UAV is disclosed comprising: a central frame 104; a pair of quick lockable fixed-wings 102 comprising right wing 102-2 and left wing 102-1 that lock with each other over the central frame; and four electrically operated rotors 108 in downward facing configuration attached to fixed-wings with help of rotor-blade arms 110. Arms 110 are pivotally fixed to wings 102 so that arms 110 are movable between a working position in which arms 110 are oriented parallel to central frame 104, and a storage position in which arms 110 are aligned with wings 102. Central frame 104 is a thin rod and works as fuselage. Drivers and control modules are fitted in wings 102. UAV includes rudders attached to arms at 45 degrees for maneuvering UAV for yaw and a secondary roll response. UAV includes two landing gears 106 attached to each end of central frame.
