Abstract:
Discloses a transformable aerial vehicle (100) and a control method thereof. The transformable aerial vehicle (100) includes: a central body (10) and at least two transformable frame assemblies (20) respectively disposed on the central body (10), each of the least two transformable frame assemblies (20) having a proximal portion pivotally coupled to the central body (10) and a distal portion; an actuation assembly (13, 5) mounted on the central body (10) and configured to pivot the at least two transformable frame assemblies (20) to a plurality of different vertical angles relative to the central body (10); and a plurality of propulsion units (30) mounted on the at least two transformable frame assemblies (20) and operable to move the transformable aerial vehicle (100).
Abstract:
An unmanned aerial vehicle (10) (UAV), or drone, includes a fuselage (12), left and right airfoil-shaped wings (14, 16) connected to the fuselage (12) to generate lift in forward flight, a left thrust-generating device (18) supported by the left wing (14), and a right thrust-generating device (20) supported by the right wing (16). The UAV further includes a vertical stabilizer (26, 32), a top thrust-generating device (28) mounted to a top portion of the vertical stabilizer (26, 32), and a bottom thrust-generating device (30) mounted to a bottom portion of the vertical stabilizer. An onboard power source (38) is provided for powering the thrust-generating devices. The left, right, top and bottom thrust-generating devices (18, 20, 28, 34) provide forward thrust during forward flight and also provide vertical thrust to enable the unmanned aerial vehicle (10) to take-off and land vertically when the fuselage (12) is substantially vertical and further enabling the unmanned aerial vehicle (10) to transition between forward flight and vertical take-off and landing.
Abstract:
The present invention discloses a driving device for connecting with a propeller. The driving device includes a body portion and a driving shaft disposed at the body portion and rotatable relative to the body portion. The driving device further includes an elastic abutting member disposed on the body portion and a lock portion disposed on the body portion. The lock portion is provided thereon with at least one first snap-fitting portion for being clamped with the propeller. The elastic abutting member is used for abutting against the propeller when the first snap-fitting portion is snapped with the propeller. The present invention further relates to a propeller and a propulsion system.
Abstract:
A method for operating an unmanned aerial vehicle (UAV) system includes directing a first, multi-rotor carrier aircraft (101) to carry a second, carried aircraft (121) aloft, and release the second aircraft for flight, while powering the first aircraft with an on-board battery, directing the first aircraft to position a capture line (106) in a flight path of the second aircraft and capture the second aircraft.
Abstract:
A flight control apparatus for fixed-wing aircraft includes a first port wing and first starboard wing, a first port swash plate coupled between a first port rotor and first port electric motor, the first port electric motor coupled to the first port wing, and a first starboard swash plate coupled between a first starboard rotor and first starboard electric motor, the first starboard electric motor coupled to the first starboard wing.

Abstract:
An aircraft is provided with a gas turbine engine having a plurality of shafts. A first shaft provides power to an electrical generator and a propeller, while a second shaft provides power to a refrigeration system. The refrigeration system may be integrated to the propeller, like a ducted fan, or on the outer skin of the aircraft.
