  • Patent number: 11970277
    Abstract: The present invention includes a hybrid propulsion system for an aircraft comprising: an engine disposed within a fuselage of the aircraft, two electrical generators disposed within the fuselage and connected to the engine, and two nacelles. Each nacelle comprises a proprotor, and each nacelle houses two electric motors connected to the proprotor. Each electrical generator is connected to the two electric motors in each nacelle. The proprotors provide lift for vertical takeoff and landing in a helicopter mode. A fan is coupled to the fuselage and connected to two additional electric motors. Each additional electric motor is connected to one of the two electric generators. The fan provides thrust for forward flight during an airplane mode. The airplane mode includes increasing power to the fan while decreasing power to the proprotors to zero.

  • Patent number: 4024828
    Abstract: This invention is for a portable signaling device which provides the user with the ability to accurately position the device in a manner to be assured that the reflections from the mirror-like surface forming a part of the signaling device are directed at the target. The signaling device includes signaling means having a plate with a surface to reflect the rays of the sun and sighting means maintained in spaced relation to the signaling means. An aperture is provided on the signaling means and the sighting means through which the user can view the target to obtain proper alignment and in turn maximum reflection from the mirror-like surface to the target. In addition, the reflective surface of the signaling means includes a set of cross hairs which are adapted to be reflected onto the sighting means such that the reflective set of cross hairs can be maintained in alignment with the aperture on the sighting means to maintain a proper alignment therebetween for maximum transmission of the signal to the target.
