An unmanned aerial vehicle (UAV) includes a fuselage, electronics disposed with the fuselage, a heat sink, and a solar shield. The heat sink is thermally connected to the electronics and includes a cooling plate disposed on or extends through an exterior surface of the fuselage. The cooling plate is exposed to an external environment of the UAV to conduct heat from the electronics to the external environment via convection. The solar shield extends over the cooling plate and defines an air scoop within which the cooling plate is disposed. The air scoop directs airflow from the external environment across the cooling plate. The solar shield shades the cooling plate from solar radiation to prevent or reduce solar heating of the cooling plate.

An electrical propulsor motor may include a stator having a hollow cylinder with an inner cylindrical surface and an outer cylindrical surface, rotor incorporated in a hub of a propulsor and mounted to the stator, including a first cylindrical surface facing the inner cylindrical surface, where the inner cylindrical surface and first cylindrical surface form a first air gap, a second cylindrical surface facing the outer cylindrical surface, wherein the outer cylindrical surface and the second cylindrical surface form a second air gap, and a plurality of axial impeller vanes mounted to at least one of the first cylindrical surface and the second cylindrical surface and within at least one of the first air gap and the second air gap and positioned to force air through the at least one of the first air gap and the second air gap when the rotor rotates about the axis of rotation.

A telescoping tail assembly for use on an aircraft that has a fore-aft length. The telescoping tail assembly includes a housing extending in an aftward direction and a tailboom slidable along the housing into various positions including an extended position and a retracted position. A jackscrew is coupled to the tailboom. An actuator is coupled to the jackscrew and is configured to selectively rotate the jackscrew to translate the tailboom between the plurality of positions. The tailboom has one or more control surfaces coupled thereto. The tailboom increases the fore-aft length of the aircraft in the extended position and decreases the fore-aft length of the aircraft in the retracted position.

An unmanned aerial vehicle having a fuselage, a water collection and emission equipment, wings, linear reinforcements, a landing gear and a vertical fin. The water collection and emission equipment has buoyancy units, a sealed cabin, a water pump and a water collection and emission pipe. The sealed cabin is detachably connected to the fuselage, and a compartment is arranged in the sealed cabin. The water pump is arranged in the compartment and the side wall of the sealed cabin has at least one concave part which is concave towards the direction of the inner cavity used for slowing down the swaying of water.

A vertical tail of a composite-wing unmanned aerial vehicle (UAV) having a body, a rudder face section, a rotor section, shock absorbing component and a quick installation assembly of circuit. The body includes a tail body frame and a shell. The rudder face section has a rudder machine and a rudder surface. The rudder surface is connected to one end of the tail for steering the directional deflection of the UAV. The shock absorbing component is connected to the lower end plate and the shock absorbing component absorbs the shock to the body. The quick installation assembly of circuit includes a plug, a positioning sleeve and a bias piece, the positioning sleeve is located on the outer circumference of the plug and slidingly connected to the plug, the bias piece is set between the plug and the positioning sleeve, the bias piece can absorb the impact on the plug.

Methods and apparatus are disclosed for deployable wing portions of an aircraft. An example method of deploying an aircraft includes separating the aircraft from a launch vehicle, the aircraft having a wing pivotably coupled to a fuselage, rotating, about an axis of rotation, the wing relative to the fuselage from a first rotational orientation to a second rotational orientation different from the first rotational orientation, wherein, in the first rotational orientation, the wing extends along a direction that substantially aligns with a longitudinal axis of the fuselage, and extending the wing in a lateral direction away from the fuselage in the second rotational orientation.

The embodiment is an unmanned aerial vehicle. The unmanned aerial vehicle includes: an airframe, including first mounting portions, where the first mounting portion includes a first mounting body and connecting rods formed on the first mounting body, the connecting rods extending in a pitch axis direction; and a power assembly, including a first assembling body and eccentric wheels mounted on the first assembling body, where the eccentric wheel is rotatable between a first rotation position and a second rotation position of the first assembling body around a rotation axis of the first assembling body, the rotation axis being perpendicular to the pitch axis direction.

The embodiments is an unmanned aerial vehicle. The unmanned aerial vehicle includes: an airframe; and a fixed-wing assembly and a rotor assembly, both replaceably connected to the airframe. The fixed-wing assembly is connected to the airframe to form a vertical take-off and landing fixed-wing unmanned aerial vehicle and the rotor assembly is connected to the airframe to form a multi-rotor unmanned aerial vehicle, thereby implementing an unmanned aerial vehicle that can switch between the vertical take-off and landing fixed-wing unmanned aerial vehicle and the multi-rotor unmanned aerial vehicle.

A solar unmanned aircraft is disclosed. The aircraft includes a first body, a second body, a main wing, a tail wing and at least four vertical control wings. The at least four control wings are all located below the main wing and the tail wing so that an upper surface of the main wing and tail wing can massively be installed with solar panels. Each of the vertical control wings has a fixed wing and a rudder. The rudder can rotate with respect to the fixed wing to control the attitude and motion of the solar unmanned aircraft.
