Electromagnetic gyroscopic stabilizing propulsion system method and apparatus is an electric gyroscope that creates magnetic fields used to rotate its flywheel. The rotation of its flywheel creates both a gyroscopic effect and thrust with airfoil shaped spokes. The invention attaches to an airframe through an articulating joint that causes the axle of the gyroscope to precess in a vertical orientation regardless of the movements/angle of the airframe. The gyroscope's thrust aligns itself with the axle of the gyroscope. The net effect is that the invention has tremendous efficiency, no external drive because it is also a motor, tremendous power from magnetic leverage of the flywheel, and stability because of the gyroscopic effect.

A compact Vertical Take-Off And Landing (VTOL) aircraft unit includes a duct fan including a propeller having a rotational axis which extends substantially vertically and discharges air downward to generate thrust sufficient for VTOL, an electric motor disposed above the duct fan and including an output shaft operatively connected to the propeller for rotating the propeller, and a cover disposed above the motor which is configured to support a load thereon. A gap is defined between the cover and the duct fan around an outer circumferential periphery of the aircraft and forms an opening of a primary flowpath for ambient air to the propeller, the primary flowpath for ambient air being non-parallel to the propeller's rotational axis.

The disclosure relates to an active stabilisation system for stabilising a payload. Embodiments can include: a first motor having a stator connected to a system mount and a rotor configured for rotation about a first axis in a first plane of rotation; a second motor having a stator connected with a first connection link to the rotor of the first motor and a rotor configured for rotation about a second axis in a second plane of rotation, the second plane of rotation intersecting with the first motor; a third motor having a stator connected with a second connection link to the rotor of the second motor and a rotor configured for rotation about a third axis in a third plane of rotation; and a payload mount connected to the rotor of the third motor and configured for attachment to a payload.

The invention relates to a vibration isolation system (VIS) comprising: a base (10); a coupling element (20) to be coupled to a vibration sensitive object; a vibration isolator (30-34) arranged between the base and the coupling element; a bellows (50) to be arranged between the VIS coupling element or the vibration isolator and a protective housing (40) surrounding the vibration sensitive object; and one or more separate damping elements to act on convolutions of the bellows.

A hybrid electric aircraft equipped with gyroscopic stabilization control is provided. In one aspect, a hybrid electric aircraft includes a turbo-generator having a gas turbine engine and an electric generator operatively coupled thereto for generating electrical power. The turbo-generator defines a rotation axis. The aircraft also includes one or more electrically-driven propulsors for producing thrust for the aircraft. In addition, the aircraft includes a pivot mount operatively coupled with the turbo-generator. To provide gyroscopic stabilization control of the aircraft, the pivot mount is controlled to adjust the rotation axis of the turbo-generator relative to a prime stability axis of the aircraft. Additionally or alternatively, a rotational speed of the turbo-generator can be changed to provide gyroscopic stabilization control of the aircraft.

The present invention comprises a novel propulsion method and apparatus for personal air vehicles generally consisting of gyroscopic movable assembly containing a gyroscope flywheel that produces thrust. In a preferred embodiment the gyroscope is hubless. The gyroscope flywheel integrates permanent magnets along its perimeter ring while spokes with an airfoil cross-section and positive incidence angle create airflow when rotated. The spokes couple the gyroscope's perimeter ring with a smaller central hubless ring. Proximate to the gyroscope's flywheel is an electromagnet fixed assembly that produces phasing electromagnetic fields that rotate the gyroscopic movable assembly. The invention comprises a self-contained apparatus with no external motor because the assembly is a motor with a self-stabilizing gyroscope that produces directional airflow that can be used to propel air, land and sea vehicles.

A multi horizontal rotor drone having a propulsion unit coupled to a payload housing by a multi-axial gimbal assembly. The centers of mass of each of these three components resides at a common point that also coincides with the pitch and roll axes (and optionally the yaw axis) of the gimbal assembly's rotational orientations. The propulsion unit has the minimal operational mass necessary while the majority of the drone's mass is located onto the payload housing. With this arrangement, the payload housing can be stabilized on its center of gravity independent of the roll, pitch and yaw changes undergoing by the propulsion unit, during the drone's flight.
