  • Patent number: 11827357
    Abstract: A precision delivery vehicle having a vehicle body assembly, a fixed wing system, a rotor system and a guidance system. The vehicle body assembly can retain a payload. The fixed wing system includes first and second wings coupled to the vehicle body for fixed wing flight. The rotor system includes a mast structure, a rotor hub rotatable about the mast structure and at least two rotor blades coupled to the rotor hub and rotatable with the rotor hub relative to the mast structure. The at least two rotor blades are movable between a collapsed configuration and a deployed configuration. In the collapsed configuration, the precision delivery vehicle is in fixed wing flight. Upon placement of the at least two rotor blades into the deployed configuration, the precision delivery vehicle is placed into rotative flight. The guidance system is structurally configured to direct the precision delivery vehicle to a target.

  • Publication number: 20170066539
    Abstract: Apparatus and methods for controlling yaw of a rotorcraft in the event of one or both of low airspeed and engine failure are disclosed. A yaw propulsion provides a yaw moment at low speeds. The yaw propulsion device may be an air jet or a fan. A pneumatic fan may be driven by compressed air released into a channel surrounding an outer portion of the fan. The fan may be driven by hydraulic power. Power for the yaw propulsion device and other system may be provided by a hydraulic pump and/or generator engaging the rotor. The generator may be used to charge a battery during autorotation or descending. Low speed yaw control may be provided by auxiliary rudders positioned within the stream tube of a prop. The auxiliary rudders may one or both of fold down and disengage from rudder controls when not in use.

  • Publication number: 20060103390
    Abstract: An arc fault circuit interrupter (AFCI) module includes a plug portion, a probe receiving portion and an AFCI test actuator for initiating a test of an AFCI protected circuit. More specifically, the plug portion includes a plurality of prongs configured to matingly engage with a standard three-prong receptacle. With this construction, upon engaging the plug portion with a AFCI protected receptacle, manipulation of the AFCI test actuator will cause a properly operating AFCI device to trip, i.e., terminate power to the AFCI protected receptacle. The module can also be provided with an AFCI circuit. The module can then be employed to protect an electrical device that is plugged into an unprotected circuit. The probe receiving portion is adapted to interconnect and expand the testing capabilities of a standard receptacle tester or, alternatively, be interconnected with various test probes associated with standard voltage testers.
