AI Technical Summary

Technical Problem

Traditional fixed-wing aircraft require runways for take-off and landing, limiting their operational versatility, while rotary-wing aircraft have lower aerodynamic efficiency and are difficult to scale. Existing transitional lift aircraft combine these types but are still limited by payload capacity.

Method used

An aircraft design integrating fixed-wing airfoils with rotating wings and ailerons or wingtip devices, using a controller to modulate lift in phased relationship with the rotatable body's revolutions, eliminating the need for runways and achieving high aerodynamic efficiency and flight control.

Benefits of technology

Enables vertical take-off and landing without runways, enhances flight control capabilities, and increases payload capacity by leveraging the efficiency of both fixed-wing and rotary-wing technologies.

Abstract

An aircraft featuring at least one lifting rotor, one or more lifting airfoil-shaped wings, and at least one thrust-generating device capable of spinning the wings or the aircraft with the wings around its centre axis, characterised by the aircraft being able to change its orientation during flight by varying the aerodynamic lift of at least one of the airfoil-shaped wings by a device or a combination of devices including but not limited to, aileron or wing tip control surfaces, orwing pitch modulation, or wing profile modulation, or by modulating the lift produced by the lifting rotors around the aircraft centre of rotation, or a combination of said devices, and with a controller for the aerodynamic lift modulating device.
