Aircraft structure
An aircraft structure ( 10 ) comprising a fuselage ( 24 ), first and second forward wings ( 20, 22 ) mounted to and/or extending from opposing sides of the fuselage ( 24 ), a continuous rear wing span ( 34 ) defining first and second rear wings ( 30, 32 ) and a central static connecting portion ( 36 ), a first wing connecting member ( 42 ) extending between the first forward wing ( 20 ) and the first rear wing ( 30 ), a second wing connecting member ( 42 ) extending between the second forward wing ( 22 ) and the second rear wing ( 32 ), wherein the rear wing span ( 34 ) is supported by a centrally located V tail joint defined by first and second angularly inclined arms ( 100, 110 ), first and second electric motors each having rotors, are mounted to each wing ( 20, 22, 30, 32 ), each rotor is pivotal between a first configuration for vertical flight, and a second configuration for forward flight.
1 . An aircraft structure comprising:
a fuselage;
first and second forward wings mounted to and/or extending from opposing sides of the fuselage;
a continuous rear wing span defining first and second rear wings and a central static connecting portion;
a first wing connecting member extending between the first forward wing and the first rear wing;
a second wing connecting member extending between the second forward wing and the second rear wing; and
first and second electric motors each having rotors, are mounted to each wing, each rotor is pivotal between a first configuration for vertical flight, and a second configuration for forward flight,
wherein the rear wing span is supported by a centrally located V tail joint defined by first and second angularly inclined arms, and
wherein the first and second angularly inclined arms are joined at a proximal lower end, and wherein the proximal lower end is mounted between a rear bulkhead of the fuselage and a tail cone such that the proximal lower end is internally housed in an internal cavity formed by the rear bulkhead and the tail cone.
2 . The aircraft structure of claim 1 , wherein each arm has a distal exposed portion which extends above the tail cone.
3 . The aircraft structure of claim 2 , wherein the distal exposed portion has an aerodynamic fairing on a leading edge.
4 . The aircraft structure of claim 3 , wherein an aerodynamic shield is located at a junction where the distal exposed portion of each arm extends upwardly beyond the fuselage.
5 . The aircraft structure of claim 1 , wherein the first and second angularly inclined arms are joined at the proximal lower end by a vertically extending mounting portion to form a Y-shaped tail support.
6 . The aircraft structure of claim 1 , wherein a span ratio is defined as a ratio of:
(a distance between a distal end of each angularly inclined arm)/(a total length of the rear wing span), and
wherein the span ratio of the aircraft structure is in a range of about 0.088 to 0.105.
7 . The aircraft structure of claim 1 , wherein the first and second angularly inclined arms are angularly offset relative to each other by about 19 to 26 degrees.
8 . The aircraft structure of claim 1 , wherein each wing has a fixed leading edge and a pivotal trailing control surface.
