    摘要: A helicopter has a propulsion system that includes a diesel engine driven electric generator, battery storage, power inverters for converting AC current to DC current and converting DC current to AC current, and an electric motor powered main rotor and an electric motor powered tail rotor. The propulsion system is integrated with electric controls of the main rotor electric motor and the tail rotor electric motor to provide additional system efficiencies. The design of the helicopter allows a single engine helicopter to be just as safe as a twin engine design helicopter while consuming less fuel. The helicopter design also includes a main rotor tilt system which tilts the rotation axis of the main rotor forward during high-speed flight to improve the aerodynamic efficiency of the helicopter airframe and rotary wing.

    摘要: A method of aircraft propulsion and control more specific to rotorcraft propulsion and control using forward, neutral and aft thrust in addition to forward/aft thrust coupling from the propulsive tail assembly through cyclic and collective pitch of the non-flapping, ridged propeller/fan blades and/or from a turbojet/turbofan vectored thrust system. The cyclic blade pitch induces a drive shaft bending moment that is used to provide aircraft directional control and also provides anti-torque control for a single rotor head helicopter. The forward/reverse collective thrust actuator, phase lag elevator effect cyclic actuator and phase lag rudder/anti-torque effect cyclic actuator do not require complex control mixing. The vectored thrust system also provides aircraft directional control and anti-torque control individually or combined with the propeller/fan assembly. This assembly eliminates the requirement of rudder or elevator control on a fixed wing aircraft and the requirement of a tail rotor on a conventional helicopter while increasing speed and maneuverability. A slowed or stopped ridged X-wing rotorcraft hub with a modified circular arc airfoil would not require cyclic/collective control.

    摘要: A rotor blade assembly is disclosed including a blade spar having a duct extending therethrough and having upper and lower surfaces. A mounting structure is secured to the blade spar and defines a fluid path in fluid communication with the duct. The mounting structure likewise has upper and lower surfaces. A tip jet is secured to the mounting structure in fluid communication with the fluid path. The blade spar and mounting structure abut one another at a joint and the upper surfaces of the blade spar and mounting structure lie on a common airfoil contour extending across the joint. The lower surfaces of the blade spar and mounting structure also lie on the common airfoil contour. One or both of the blade and mounting structure include a composite material. The mounting structure may include two portions secured to one another having a distal portion of the blade spar captured therebetween.
