The present invention relates to a rotary-wing drone (1) comprising a frame in which are located: - a set of sensors (13) designed for performing tasks of surveillance and/or intelligence gathering and/or assisting with the guidance of the drone (1), and - a control unit (14) associated with this set of sensors (13), characterized in that it comprises a diesel engine (4).
Abstract:
The present invention is a rotary device that may be adapted for use as a propeller assembly and electrical generator for aerial vehicles or other vehicles intended for fluid media. In one example, the device includes a ring assembly (31) having a plurality of centrally linked blades (33) coupled to a rotatable common hub (5). Rotary motion of the ring assembly (31) is facilitated by couplin it to an opposed cylinder (1100), opposed piston (1120), internal combustion. The ring assembly (31) includes components of an electrical power generating system so that electrical power is produced from the rotation of the ring assembly (31).
Abstract:
An aircraft attack interdiction system using an unmanned interdiction aircraft piloted using a remote control system. In-flight refueling system, weapons launcher systems and intelligence gathering equipment are mounted on the interdiction aircraft. A remote flight control operator to remotely fly the interdiction aircraft can be based on a remote flight control commander aircraft that can be flown at safe distances from targets that are attacked by the interdiction aircraft
Abstract:
An unmanned aerial vehicle (UAV) having a design for optimum stowability and low cost. The UAV having a collapsible wing section which can be easily removed from the fuselage, allowing for quick assembly and disassembly and ease of portability. The unmanned aerial vehicle includes a primary wing assembly, a fuselage, a means for propelling the unmanned aerial vehicle , and means for remotely controlling the unmanned aerial vehicle.

Abstract:
A remote-control powered parafoil aircraft has an aircraft body (1) that is engine powered and hung with lines (2) from an air-expandable wing (3, 20). The lines include control lines (15) with which air flow and aerodynamic shape of the air-expandable wing are variable selectively from a foil controller (18, 19, 20) on the aircraft body for flight-mode control. Sight from a television camera (8) on the aircraft body is televised to a control unit (9) from which control data is transmitted selectively from proximate the control unit to the foil controller (14) with a multi-axis joystick or similar control, to an engine (6) on the parafoil body from an engine controller (24) and to an item servo (29) for control of optional items (45) on the aircraft body.
Abstract:
An unmanned aerial vehicle (UAV) (10) has a composite toroidal fuselage structure (20) that surrounds a rotor assembly (100) that includes pair of coaxial, multi-bladed, counter-rotating rotors (200, 202). The toroidal fuselage structure (20) includes an annular C-shaped structure (430) that defines an internal cavity (436) and removable panel structures (464) mounted in combination with the annular C-shaped structure (430). The UAV has a drive train assembly (60) that includes a sprag clutch (62), an engine coupling subassembly (63), a transmission coupling subassembly (74), and a drive shaft (72) operative to couple torque between the UAV engine (54) and the rotor assembly (100) and configured to maximize allowable axial, angular, and/or parallel misalignments therebetween. The UAV further includes a coaxial transmission/center hub assembly (110), an integrated spline/cone seat subassembly (190), rotor blade subassemblies including pretwisted inner flexbeams (260), and snubber assemblies (230).
