Filed:

Aug 15, 2012

Appl. No.:

13/586020

Inventors:

Dudley E. Smith - Arlington TX, US
Walter C. Joiner - Arlington TX, US
Daniel B. Robertson - Southlake TX, US

Assignee:

Textron Innovations Inc. - Providence RI

International Classification:

B64C 27/28

US Classification:

244 7C

Abstract:

A twin-rotor side-by-side compound rotorcraft has a fuselage and variable incident wing assembly that pivots relative to fuselage. The aircraft also has landing gear assembly and a tail fin assembly. The variable incident wing assembly is pivotally attached to the fuselage, and includes wing members, engines fixedly mounted to the wing members or another area of the rotorcraft, and a mast attached at a fixed angle relative to the wing members. Then engines may also be located near the fuselage or another area of the rotorcraft. The variable incident wing assembly is capable of pivoting about a pivot axis, thereby allowing mast orientation in at least a hover mast position and a forward flight mast position. The rotors provide additional forward thrust and the wings provide additional lift, when the mast is in the forward flight mast position.
