Abstract: An unmanned aircraft includes three parallel beams extending in at least one longitudinal direction X from a rear side to a front side of the aircraft, the central beam forming a main fuselage containing a powertrain, with a propeller of diameter D configured to be driven by the powertrain being attached to a front end of the central beam, each side beam being at a distance L/2 from the central beam and each side beam supporting a radar at a front end of the beam.

Abstract: An aircraft includes an airframe including a fuselage, a wing, and a tail, a main propulsion unit, including a motor and a propeller, a flight control device, including electric actuators, movable surfaces and sensors, and an autopilot computer sending instructions to the main propulsion unit and to the flight control device. Such unmanned aircraft further includes a pair of auxiliary propulsion units, each auxiliary propulsion unit including an electric motor, a propeller driven by the electric motor, and means for orienting the plane of the propeller with respect to the airframe, the flight control computer being programmed for setting a steering angle and a propeller speed of each auxiliary propulsion unit so as to compensate for a malfunction of the flight control system and/or of the main propulsion unit, in order to control the trajectory along all axes, the unmanned aircraft thereby exhibiting increased reliability.

Abstract: The present invention relates to an aid system (30) for piloting an aircraft, the aircraft including at least two piloting units each having at least one piloting member that can be actuated by a pilot to command at least one control surface of the aircraft. The piloting aid system (30) includes a module (32) for detecting actions performed on at least one piloting unit and a feedback module (34) indicating, via a man-machine interface (24A, 24B) separate from the piloting members, the movement of said piloting member and/or the force exerted on said piloting member.

Abstract: This method makes it possible to generate a resulting setpoint trajectory of an aircraft, a guiding system controlling the trajectory of the aircraft relative to the resulting setpoint trajectory. The generating method is implemented by an electronic device and comprises selecting at least one mode from among several operating modes, acquiring a setpoint trajectory prepared by a flight management system, obtaining an alternative setpoint trajectory from an element from among a module for computing a trajectory and an external generating system, and generating the resulting setpoint trajectory, which includes one or several segments of the alternative setpoint trajectory for the period of time corresponding to the selection of another mode.

Abstract: A method and device for generating at least one set point from a flight control set point, a motor control set point and an aircraft guidance set point, a related computer program product and an aircraft are disclosed. In one aspect, the method includes acquiring a mechanical property relative to at least one corresponding primary control member and computing at least one set point from among one or more primary set points and one or more secondary set points. The method also includes generating at least one of the computed set point(s) and switching, based on the mechanical property acquired for the corresponding primary control member, between a first mode in which one or more primary set points are generated and a second mode in which one or more secondary set points are generated.
