    Abstract: Provided are computer-implemented methods for autonomously controlling an aircraft with vertical take-off and landing capabilities and folding wings that includes controlling a plurality of thrust producing components of an aircraft to cause the aircraft to rise vertically when wings of the aircraft are in a first folded configuration, where when the wings of the aircraft are in the first folded configuration, a leading edge of each wing is oriented in a vertical direction setting motor controller gains based on the wings of the aircraft being in the first folded configuration, and causing the aircraft to align with a direction of airflow when the wings of the aircraft are in the first folded configuration, and controlling thrust producing components and control surfaces and internal articulation mechanisms of the aircraft to cause the aircraft to transition from folded wing configuration to unfolded wing configuration. Systems and computer program products are also provided.

    Abstract: A VTOL fixed wing aircraft capable of high-speed forward flight. The aircraft has a main wing internally reinforced with front and aft spars. Spar boxed are located in roll-balanced locations along the wing. Each spar box serves as a connection point for a support linkage that supports a leading-edge and trailing-edge propulsion unit. The leading-edge propulsion unit is fitted with a puller propeller and designed for articulated movement between a VTOL position in front of the wing leading edge and a forward flight position below the wing leading edge. The trailing-edge propulsion unit is fitted with a pusher propeller and designed for articulated movement between a VTOL position in behind the wing trailing edge and a forward flight position above the wing leading edge. The propeller includes a propulsor thrust ring having an aerodynamic profile and a thrust nozzle to capture and vector radial air leakage into thrust.

    Abstract: A variable-geometry vertical takeoff and landing (VTOL) aircraft system may transport passengers from a departure point to a destination via partially or fully autonomous flight operations. The VTOL aircraft system may operate in hover-based ascent/descent modes, level-flight cruising modes, and transitional modes between the two. Thrust may be provided by ducted propeller units articulable relative to the fuselage; by articulating the airfoil struts connecting the thrust sources to the fuselage the thrust sources may be manipulated for ascent/descent, transition, and cruising, in order to control ascent, descent, and cruise. More precise thrust control may be achieved by further articulation of the annular propeller ducts relative to the airfoil struts. The airfoil struts and propeller ducts may present a wing-shaped or variably segmented cross section to maximize achievable lift.

Четыре крыла выполнены с возможностью раскладываться в плоскость корпуса из положения, перпендикулярного плоскости корпуса. ЛА содержит вертикальный стабилизатор, ручные и ножные элементы управления, расположенные в передней и задней частях корпуса соответственно. Четыре силовых агрегата выполнены с возможностью поворота и попарно закреплены на концах корпуса. Каждый силовой агрегат представляет собой двигатель с воздушными винтами в защитном кожухе. Корпус выполнен с возможностью размещения на нем пилота в положении, в котором фронтальная плоскость пилота параллельна плоскости корпуса. Обеспечивается повышение аэродинамических характеристик благодаря уменьшению лобового сопротивления.
