A vertical takeoff and landing aircraft, using for vertical lift and lateral thrust a redundant plurality of essentially similar electrically-powered and electronically-controlled thrust units mounted in a mechanically static or fixed fashion relative to one another in a substantially horizontal plane. The thrust units are situated in this planar array in aerodynamically approximate pairs, such that a complete failure of a single thrust unit would not substantially compromise the ability of the aircraft to maintain flight.

A method and apparatus provide for automatically controlling the flight of a tiltrotor aircraft while the aircraft is in flight that is at least partially rotor-borne. The method and apparatus provide for automatically tilting nacelles in response to a longitudinal-velocity control signal so as to produce a longitudinal thrust-vector component for controlling longitudinal velocity of the aircraft. Simultaneously, cyclic swashplate controls are automatically actuated so as to maintain the fuselage in a desired pitch attitude. The method and apparatus also provide for automatically actuating the cyclic swashplate controls for each rotor in response to a lateral-velocity control signal so as to produce a lateral thrust-vector component for controlling lateral velocity of the aircraft. Simultaneously, collective swashplate controls for each rotor are automatically actuated so as to maintain the fuselage in a desired roll attitude. The method and apparatus provide for yaw control through differential longitudinal thrust produced by tilting the nacelles.

A tail assembly (10) for a rotorcraft (20), the tail assembly (10) comprising a first stabilizer (3) extending transversely on either side of an anteroposterior plane (P1), and a second stabilizer (4, 4″) extending in elevation. Two propellers (31, 41) positioned on either side of the anteroposterior plane (P1) provide the rotorcraft (20) with at least part of its yaw control and its propulsion. The axes of the two propellers (31, 41) are situated in a plane substantially parallel to the horizontal plane (P3) and they intersect at a position in the anteroposterior plane (P1) of the rotorcraft (20) that is located between the front end of the rotorcraft (20) and the propellers (31, 41). Using both propellers (31, 41) of the tail assembly (10) simultaneously makes it possible to provide the rotorcraft (20) with longitudinal thrust while conserving its transverse thrust for the anti-torque function, it being possible to control these two thrusts independently.

The invention consists of a prototype comprising three moving parts that can realistically simulate all the forces which subject a driver positioned in any moving vehicle. The first part has a circular motion with respect to its vertical axis of rotation and is supported by a fixed base, the second part, integral to the first part has a longitudinal movement (horizontal) perpendicular to the rotation axis of the first part. The third part, integral to the second part, acts as positioning for the user who is subject to the simulator's effects which has a circular motion with respect to its vertical axis of rotation that is parallel to the axis of rotation of the first part. The longitudinal movement of the second part in synergy with the first rotation of the first part and the instantaneous angular positioning of the third part, can continuously represent a development of any force such as acceleration, deceleration (braking) and lateral thrust present in any moving phase of a vehicle.

The invention simulates high acceleration in any dynamic condition, reproducing, thanks to the installation of small size motors, the sensations felt inside high powered vehicles (eg. F1 car).

The principle underlying the present invention is that at any moment, a person, who is inside a moving vehicle, being subjected to a resulting force, which, if it was artificially reproduced constantly, makes it imperceptible from a real driving situation.

Present mechanic emulators, despite the existing varieties and their differentiation in size and type of movement, have physical limits in creating realistic sensations of driving. They are not capable of reproducing a faithful simulation, such as direction and intensity of strength of the force which the driver is subjected to, but above all they do not reproduce the simulation of these forces continuously over time.

This invention is strongly innovative compared to those previous because it makes it possible to manufacture simulators which generate realistic physical sensations of intensity, direction, speed of transitional reply and persistence in time, so that a user cannot distinguish between reality and fiction. This total realism is achieved without the necessity of using high powered and expensive motors, thanks to the synergy of movement of the simulator components, so that the invention can be manufactured immediately.

A propulsion system comprising independent rotor sub-systems producing a thrust force of a desired magnitude in any desired radial direction from the centre of the propulsion system, driven from a single driveshaft that may be fixed in its position in the vehicle. When the propulsion system is fitted, for example, to a single-main-rotor helicopter in place of the convention anti-torque tail rotor, the helicopter is thereby equipped with a propulsion system that can produce yaw, pitch, the anti-torque lateral thrust for stability in hover, aft thrust or drag as well as the direct forward thrust that will enable the helicopter to fly at higher speeds. The propulsion system may also be applied in other aeronautical systems as well as to marine and industrial systems to impart energy into a fluid and thereby induce movement in that fluid.

A thrust drive unit for generating side thrust for improved maneuverability of a marine vessel employs a peripherally-driven propeller situated below the waterline and remotely powered by a motor situated well above the waterline via a drive belt. The propeller is supported by the two ends of the coaxial shaft by a pair of supports which are mounted on either side of the casing and are angularly adjustable with respect thereto about the thrust axis to a position which is least resistance-generating for a particular installation of the thrust drive unit on a vessel.
