Abstract

Official abstract text for this publication.

An aircraft that includes a canard having a leading edge and a trailing edge, a forward swept and fixed wing having a trailing edge, and a plurality of tilt rotor submodules, a dovetail, and a T-tail. The plurality of tilt rotor submodules are coupled to the trailing edge of the forward swept and fixed wing. The dovetail is attached to an underside of a fuselage. The T-tail is located above the dovetail. A horizontal plane of the T-tail is at a height that is higher than a horizonal plane of the forward swept and fixed wing.

First claim

Opening claim text (preview).

What is claimed is: 1 . An aircraft, comprising: a canard having a leading edge and a trailing edge; a forward swept and fixed wing having a trailing edge; a plurality of tilt rotor submodules that are coupled to the trailing edge of the forward swept and fixed wing; and a dovetail attached to an underside of a fuselage; and a T-tail located above the dovetail, wherein a horizontal plane of the T-tail is at a height that is higher than a horizonal plane of the forward swept and fixed wing; wherein the fuselage rests on the dovetail when the aircraft is on the ground. 2 . The aircraft of claim 1 , wherein the horizontal plane of the forward swept and fixed wing is at a height that is higher than a horizontal plane of the canard. 3 . The aircraft of claim 1 , wherein the plurality of tilt rotor submodules includes two tilt rotor submodules that are coupled to the canard and six tilt rotor submodules that are coupled to the forward swept and fixed wing. 4 . The aircraft of claim 1 , wherein the forward swept and fixed wing has a relative lifting force within a range of 80% to 100%, inclusive, during a cruise mode. 5 . The aircraft of claim 1 , wherein an inboard section of the forward swept and fixed wing has a twist angle within a range of −5° to 0°, inclusive. 6 . The aircraft of claim 1 , wherein a middle section of the forward swept and fixed wing has a twist angle within a range of 0° to 5°, inclusive. 7 . The aircraft of claim 1 , wherein an outboard section of the forward swept and fixed wing has a twist angle within a range of −5° to 0°, inclusive. 8 . The aircraft of claim 1 , wherein an outboard section of the forward swept and fixed wing stalls after the canard. 9 . The aircraft of claim 1 , wherein an outboard section of the forward swept and fixed wing stalls after the rest of the forward swept and fixed wing. 10 . The aircraft of claim 1 , wherein the T-tail is located at the height of 0.7 to 1.2 meters above a base of the aircraft. 11 . A method, comprising: providing a canard having a leading edge and a trailing edge; providing a forward swept and fixed wing having a trailing edge; providing a plurality of tilt rotor submodules that are coupled to the trailing edge of the forward swept and fixed wing; and providing a dovetail attached to an underside of a fuselage; and providing a T-tail located above the dovetail, wherein a horizontal plane of the T-tail is at a height that is higher than a horizonal plane of the forward swept and fixed wing; wherein the fuselage rests on the dovetail when the aircraft is on the ground. 12 . The method of claim 11 , wherein a horizontal plane of the forward swept and fixed wing is at a height that is higher than a horizontal plane of the canard. 13 . The method of claim 11 , wherein the plurality of tilt rotor submodules includes two tilt rotor submodules that are coupled to the canard and six tilt rotor submodules that are coupled to the forward swept and fixed wing. 14 . The method of claim 11 , wherein the forward swept and fixed wing has a relative lifting force within a range of 80% to 100%, inclusive, during a cruise mode. 15 . The method of claim 11 , wherein an inboard section of the forward swept and fixed wing has a twist angle within a range of −5° to 0°, inclusive. 16 . The method of claim 11 , wherein a middle section of the forward swept and fixed wing has a twist angle within a range of 0° to 5°, inclusive. 17 . The method of claim 11 , wherein an outboard section of the forward swept and fixed wing has a twist angle within a range of −5° to 0°, inclusive. 18 . The method of claim 11 , wherein an outboard section of the forward swept and fixed wing stalls after the canard. 19 . The method of claim 11 , wherein an outboard section of the forward swept and fixed wing stalls after the rest of the forward swept and fixed wing. 20 . The method of claim 11 , wherein the T-tail is located at the height of 0.7 to 1.2 meters above a base of the aircraft.
