  • Patent number: 11117657
    Abstract: An aeronautical apparatus is disclosed that has two pairs of wings. Each wing has a thrust-angle motor. A propeller and propeller motor are coupled to each thrust-angle motor. Propeller pitch is controlled by a propeller-pitch motor. The thrust-angle motor allows the propeller axis of rotation to be parallel to the fuselage's longitudinal axis; vertical (perpendicular to longitudinal axis, as in well-known fixed-position, four-propeller drones); and any position between as well as a given range exceeding these bounds which is used for control. An electronic control unit is electronically coupled to the thrust-angle motors, propeller motors, and propeller-pitch motors, which can be independently controlled, to provide the desired thrust and trajectory. Such an apparatus can provide efficient operation in vertical take-off/landing (hovering) and forward (translational) flight modes.

  • Patent number: 11117677
    Abstract: A system and method of compensating for airspeed when measuring pressure drop across a filter system on an aircraft may include a pressure compensator, an internal pressure sensor, and an external pressure sensor. A filter media may be located around a housing such that air flows through the filter media into a clean air space defined by the filter media and the housing. The pressure compensator may be located outside of the clean air space and within an airstream of the aircraft. The internal pressure sensor may be configured to measure an internal pressure that varies with airspeed and the external pressure sensor may be located on the pressure compensator to measure an external pressure. The external pressure sensor may be positioned such that the external pressure varies according to a known relationship relative to the internal pressure as the airspeed of the aircraft changes.
