Package delivery by means of an automated multi-copter uas/uav dispatched from a conventional delivery vehicle
ActiveUS20160200438A1Substantial fuel savingReduce operating costsRemote controlled aircraftVehicular energy storageDocking stationDelivery vehicle
Methods and associated systems for autonomous package delivery utilize a UAS / UAV, an infrared positioning senor, and a docking station integrated with a package delivery vehicle. The UAS / UAV accepts a package for delivery from the docking station on the delivery vehicle and uploads the delivery destination. The UAS / UAV autonomously launches from its docked position on the delivery vehicle. The UAS / UAV autonomously flies to the delivery destination by means of GPS navigation. The UAS / UAV is guided in final delivery by means of a human supervised live video feed from the UAS / UAV. The UAS / UAV is assisted in the descent and delivery of the parcel by precision sensors and if necessary by means of remote human control. The UAS / UAV autonomously returns to the delivery vehicle by means of GPS navigation and precision sensors. The UAS / UAV autonomously docks with the delivery vehicle for recharging and preparation for the next delivery sequence.

Aircraft landing gear comprised of a wheel hub motor / generator disks stack, includes alternating rotor and stator disks mounted with respect to the wheel support and wheel. The wheel hub motor / generator can provide motive force to the wheel when electrical power is applied, which may be applied prior to touch-down thus decreasing the difference in relative velocities of the tire radial velocity with that of the relative velocity of the runway thus greatly reducing the sliding friction wear of said tire. After touchdown the wheel hub motor / generator may be used as a generator thus applying a regenerative braking force and / or a motorized braking action to the wheel. The energy generated upon landing maybe dissipated through a resistor and / or stored for later use in providing a source for motive power to the aircraft wheels for the purpose of taxiing and ground maneuvers of said aircraft.

Rapidly convertible hybrid aircraft and manufacturing method
InactiveUS20110036939A1Easy to convertAvoid many safety and emissionInfluencers by generating vorticesConvertible aircraftsCruise speedControl system
A hybrid fixed wing aircraft converts into a roadworthy vehicle in a matter of seconds therefore operating efficiently in both air and ground transportation systems. The single piece wing is mounted on a skewed pivot that is on the lower portion of the fuselage and is operated by a pushbutton operating system. The aircraft includes telescopic twin boom tail design that when extended allows good pitch stability and damping. The aircraft's wing area may be increased with additional telescopic wing tip segments. This allows an increase in aspect ratio, hence improving efficiency at high loads. This feature will also creates a reduction in induced drag at cruise speed by simply retracting the tips in flight. The vehicle has a unique synchronized control system that switches from flight to ground mode without input from the operator, thereby providing a natural interface for the operator.

Aircraft kinetic landing energy conversion system
ActiveUS20080258014A1Increase braking powerAvoid heatArresting gearRailway vehiclesElectric potential energyElectric generator
A kinetic energy system which transfers the kinetic landing into recoverable electric energy for an aircraft. The system incorporates at least one wheel supporting the aircraft for landing and takeoff coupled with a dynamic functioning motor / generator mounted to and operated by rotation of the wheel to create electrical energy from kinetic energy. An induction shoe structurally connected to the aircraft and electrically connected to the motor / generator, which shoe draws the converted energy from the generator which supplies the load created by the inductively coupled induction shoe to the an ancillary load provided by the resistive heat sink on by the capacitor storage bank. This provides the generator circuit for conversion of the rotational energy of the wheel to electrical energy and creates braking drag. In exemplary embodiments, the system employs an energy storage system acting as the load to store electrical potential energy created by the generator. Additionally, the generator is employable as a motor, receiving energy from the storage system for traction power to the associated aircraft wheel. An induction grid or a surface mounted conductive layer mounted into or onto a runway is employed for transferring energy to and from the motor / generator.
