Disclosed is an electrically powered, reaction-drive type rotorcraft. Thrust generators on the outer portion of each rotor blade cause the rotors to spin and generate lift, and additionally, may be controlled to produce variable amounts of thrust as the rotor blades rotate through different sectors around a generally non-rotating fuselage such that net lateral forces are produced to control the position and velocity of the vehicle. The rotorcraft may also employ aerodynamic surfaces on each rotor blade whose parts or entire structure can be moved to produce net lateral and vertical forces for control of position and velocity of the vehicle. The rotorcraft, which may be operationally carbon-neutral, stores its electrical energy in batteries and other optional energy storage methods, and may harvest solar energy using arrays of photovoltaic cells disposed on its upper surfaces. Vehicle sizes may range from small Uncrewed Air vehicle Systems to large crewed aircraft.

The present disclosure is directed toward methods, non-transitory computer-readable media, and systems for trajectory optimization in a high-altitude, long-endurance aircraft. For example, the systems described herein can generate an optimized flight plan for an aircraft during active flight of the aircraft by utilizing a greedy algorithm with buffering. In one or more embodiments, the systems described herein identify a plurality of possible states and select a predetermined number of the top possible states (based on energy change associated with transitioning to each possible state) at each incremental time period within a flight time window starting from an initial state to a plurality of possible states for a final incremental time period. Furthermore, in some embodiments, the systems described herein select a final state based on a final energy associated with the final state and determine a flight plan for the aircraft from the initial state to the selected final state.

Provided is a control device that controls a power supply flight vehicle, the control device including a control unit which controls the power supply flight vehicle so as to cause a light irradiation unit to radiate light toward a solar cell panel while flying following flight of a power supply target flight vehicle on which the solar cell panel is mounted. Provided is a control method to control a power supply flight vehicle, which is executed by a computer, the control method including controlling the power supply flight vehicle so as to cause a light irradiation unit to radiate light toward a solar cell panel while flying following flight of a power supply target flight vehicle on which the solar cell panel is mounted.

A manned or unmanned aircraft has a main body with a circular shape and a circular outer periphery. One or more rotor blades extend substantially horizontally outward from the main body at or about the circular outer periphery. In addition, one or more counter-rotation blades extend substantially horizontally outward from said main body at or about the circular outer periphery, but vertically offset from the main rotor blades.

An airfoil body for an aircraft extending from an inner end to an outer end, and between a leading edge and a trailing edge, comprising an airfoil skin, a planar sheet disposed below the airfoil skin including an array of transducer elements attached to the planar sheet comprising one or more of: (i) an array of semiconductor sensors not including solar cells; (ii) an antenna array and (iii) thermal transfer elements.

As it is scientifically known all or nearly all celestial bodies have magnetic fields to varying degrees including Earth. Many celestial bodies also have a gaseous atmosphere. The present invention utilizes said magnetic fields and or gaseous atmospheres in conjunction with a plurality of electric grids, coils, or super conducting slats to which varying levels of positive voltage are applied to produce electric power. A plurality of electric grids, coils, or super conducting slats may be installed on automobiles, aircraft, spacecraft, and onto the blades of a wind powered electrical generating system to produce electric power when the blades are in motion.

An air duct system for an aircraft provides passengers with light, data, electrical power, and sanitized air. The air duct system includes an air duct having a main body and a visible light source configured to generate visible light, where the visible light is modulated by one or more controllers based on a visible light communication protocol. The air duct system simultaneously achieves four functions for improving passengers' flying experience. First, a portion of the visible light transmitted by the air duct illuminates the interior cabin of the aircraft. Second, by modulating the visible light, the air duct system transmits and distributes data that is received by the passengers' electronic devices. Third, a portion of the visible light is converted into electrical power at each passenger seat to power passengers' electronic devices. Fourth, in embodiments, the visible light is emitted at a germicidal wavelength spectrum to create sanitized air.
