A vehicle is described having an aerodynamically contoured lifting body comprising a plurality of cooperating body modules, wherein at least two of the modules are displaceably secured to each other. The modules include a thrust vectoring module operatively coupled to a propulsive mechanism. The thrust vectoring module is dynamically controlled to affect positioning and actuation of the propulsive mechanism to attain a desired positioning of the vehicle and at least one of a plurality of modes of operation thereof. The thrust vectoring module includes a nacelle module carrying the propulsive mechanism thereon and rotatably displaceable about one or more axes extending from the lifting body. The propulsive mechanism is positioned externally, internally, or in combinations thereof of the nacelle module and is tiltably displaceable about one or more axes of the nacelle module.

An aircraft includes a fuselage having a longitudinal axis, a wing assembly, and a fuselage positioning mechanism operatively connecting the fuselage to the wing assembly. The fuselage positioning mechanism is operable to move the fuselage relative to the wing assembly in a longitudinal direction parallel to the longitudinal axis between a fuselage maximum forward position and a fuselage maximum aft position. When the aircraft for flight, a position of a center of gravity of the aircraft relative to a center of lift is determined. The fuselage can be moved relative to the wing assembly to bring the center of gravity within an allowable range of distances from the center of lift to balance the aircraft for flight. The fuselage positioning mechanism can be automated to allow adjustment of the fuselage position during the flight of the aircraft.

A propulsion system coupled to a vehicle. The system includes a convex surface, a diffusing structure coupled to the convex surface, and at least one conduit coupled to the convex surface. The conduit is configured to introduce to the convex surface a primary fluid produced by the vehicle. The system further includes an intake structure coupled to the convex surface and configured to introduce to the diffusing structure a secondary fluid accessible to the vehicle. The diffusing structure comprises a terminal end configured to provide egress from the system for the introduced primary fluid and secondary fluid.

An ejector system for propelling a vehicle. The system includes a diffusing structure and a duct coupled to the diffusing structure. The duct includes a wall having openings formed therethrough and configured to introduce to the diffusing structure a primary fluid produced by the vehicle. An airfoil is positioned within the flow of the primary fluid through the openings to the diffusing structure.

A vehicle, includes a main body. A fluid generator is coupled to the main body and produces a fluid stream. At least one fore conduit and at least one tail conduit are fluidly coupled to the generator. First and second fore ejectors are fluidly coupled to the fore conduit, coupled to the main body and respectively coupled to a starboard side and port side of the vehicle. The fore ejectors respectively comprise an outlet structure out of which fluid flows. At least one tail ejector is fluidly coupled to the tail conduit. The tail ejector comprises an outlet structure out of which fluid flows. A primary airfoil element is coupled to the tail portion. A surface of the primary airfoil element is located directly downstream of the first and second fore ejectors such that the fluid from the first and second fore ejectors flows over the such surface.

A propulsion system coupled to a vehicle. The system includes an ejector having an outlet structure out of which propulsive fluid flows at a predetermined adjustable velocity. A control surface having a leading edge is located directly downstream of the outlet structure such that propulsive fluid from the ejector flows over the control surface.

A propulsion unit includes a motor rotor that spins about a central rotational axis, propeller blades each having a proximal base and a distal tip, and pivot mounts each coupling the proximal base of a corresponding one of the propeller blades to the motor rotor. The propeller blades each freely pivot at the proximal base about a corresponding offset pivoting axis that is substantially parallel to but offset from the central rotational axis of the motor rotor.

A propulsion unit includes a motor rotor, a clip-in base mount, a clip-in rotor cap, propeller mounts, and propeller blades. The motor rotor spins about a central rotational axis. The clip-in base mount is disposed on the motor rotor. The clip-in rotor cap is shaped to mate with and detachably clip into the clip-in base mount. The propeller mounts are attached to the clip-in rotor cap. The propeller blades each have a proximal base and a distal tip. The proximal base of each propeller blade mounts to a corresponding one of the propeller mounts.

A control system of a flight vehicle automatically varies the relationship between the center of gravity and the center of pressure of the flight vehicle. The control system automatically adjusts a center of pressure of the flight vehicle depending on a varying payload or payload type that is removably couplable to the flight vehicle. The control system automatically limits translational movement of the one or more wings of the flight vehicle in response to coupling of a payload to a fuselage of the flight vehicle.

A device can provide an air state detection floating device capable of remaining in the air, the device comprising: a power supply unit; at least one memory for storing instructions; at least one processor; a communication unit for transmitting and receiving data; a driving unit for generating a driving force; a first sensing unit for detecting information on an air state of an enclosed space; and a second sensing unit for generating location information, wherein the instructions are executable by the processor so as to the processor to perform operations, and the operations comprise: an operation that generates a control signal for movement in the enclosed space on the basis of the data; and an operation that controls the driving unit based on the control signal.
