Problems solved by technology

However, it is more difficult to control a tilting wing during a hover because the vertically tilting wing provides a large surface area for crosswinds, which typically requires a tilting wing aircraft to have cyclic rotor control or additional thrust stations to generate moment aircraft

Embodiment Construction

[0020] While the making and using of various embodiments of the present disclosure are discussed in detail below, it should be appreciated that the present disclosure provides many applicable inventive concepts that can be embodied in a wide variety of specific situations. The specific embodiments discussed herein are illustrative only and do not limit the scope of the disclosure. In the interest of clarity, not all features of an actual implementation may be described in this disclosure. It should of course be understood that in the development of any such actual implementation many implementation-specific decisions must be made in order to achieve the developer's specific goals, such as compliance with system-related and business requirements that vary from implementation to implementation. related restrictions. In addition, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking for those ...

Abstract

The invention provides an aircraft having a vertical takeoff and landing fight mode and a forward flight mode. The aircraft includes a fuselage and an X-tiltwing that is rotatable relative to the fuselage between a vertical lift orientation and a forward thrust orientation. The X-tiltwing has oppositely disposed V-wing members each having first and second wing sections. In the vertical lift orientation, the first and second wing sections of each V-wing member are generally in the same horizontal plane. In the forward thrust orientation, the first and second wing sections of each V-wing memberare generally in the same vertical plane. A distributed propulsion system is attached to the X-tiltwing such that a plurality of propulsion assemblies is attached to each wing section. A flight control system is operably associated with the distributed propulsion system to independently control each of the propulsion assemblies.

Description

technical field [0001] The present disclosure relates generally to aircraft operable to transition between a forward flight mode and a vertical take-off and landing flight mode, and in particular to an aircraft having a flight control system responsive to autonomous flight controls, remote flight controls, on-board pilot flight controls, and / or combinations thereof while operating an X-shaped tilt-wing aircraft with a distributed propulsion system. Background technique [0002] A fixed-wing aircraft, such as an airplane, is capable of flying using wings that generate lift in response to the aircraft's forward airspeed, which is generated by thrust from one or more jet engines or propellers . Wings typically have an airfoil cross-section that deflects air downward as the vehicle moves forward, thereby generating lift to support the vehicle in flight. However, fixed wing aircraft typically require runways hundreds or thousands of feet long for takeoff and landing. [0003] ...
