Abstract: A dual-state propulsion aircraft includes an aircraft fuselage; and at least one dual-state propulsion system, including a fixed nacelle, a rotatable nacelle optionally including a front curved section and rear straight section, mechanical nacelle rotation stops, mechanical shaft rotation stops, a motor, and a thruster with pivotable blades; such that the at least one dual-state propulsion system is rotatable to a first system position configured for horizontal flight and to a second system position configured for vertical flight.

Abstract: A rotatable thruster aircraft includes an airframe, which includes an aircraft body and a fixed wing; rotatable thruster assemblies, each including first and second thrusters that provide rotation via differential thrust; a rotatable shaft with torsional flexibility; an inertial measurement unit; optionally vertical lift thrusters; and an aircraft control unit, including a processor, a non-transitory memory, an input/output component, and a power manager that controls specific power applied to the thrusters.

Abstract: A pivoting wing system, capable of vertical take-off and landing, having a hub connected to one or more wings provided on a spanwise axis. The wings are further provided with one or more thrust producing devices mounted to the top and bottom of the wings. The thrust producing devices are configured pivot the wings about the spanwise axis. The wings generate lift for forward flight situations, and the configuration allows for controlled vertical and horizontal flight. The wings may also be configured as rotary elements and enable the system to take flight like a helicopter.

Abstract: A zero transition vertical take-off and landing (VTOL) aircraft, which is stable in all levels of flight, especially the transition phase from vertical to horizontal flight. The zero transition VTOL aircraft is capable of achieving both vertical and horizontal flight without changing the positioning of thrusters, such as through the use of tiltable or rotatable nacelles or wings. Rather a front thruster assembly and a rear thruster assembly are positioned at specific angles in relation to each other along at least one fuselage in order to generate the desired ratio of vertical to horizontal thrust. At least one wing is also positioned at a specific wing angle in order to achieve a desired angle of attack when in horizontal flight. The attitude of the zero transition VTOL aircraft can be controlled through the use of differential thrust alone, or in conjunction with control surfaces.
