Abstract

An aircraft with rear mounted engines, comprising a vertical tail plane and a horizontal tail plane, in which the engines are mounted on top of the horizontal tail plane, such that the horizontal tail plane comprises an inner fixed part attached to the fuselage of the aircraft, the inner fixed part comprising an elevator, and two outer movable parts, each one of the outer movable parts being located at each side end of the horizontal tail plane which is furthest away from the fuselage of the aircraft, such that both the inner fixed part and the outer movable parts are at least partially subjected to a flow coming from the engines when the engines are in use.

First claim

The invention claimed is:

1. An aircraft with rear mounted engines, comprising:
a vertical tail plane, and
a horizontal tail plane,
wherein the engines are mounted on top of the horizontal tail plane,
wherein the horizontal tail plane comprises:
an inner fixed part attached to a fuselage of the aircraft, the inner fixed part comprising an elevator, and
two outer movable parts, each one of the outer movable parts being located at each side end of the horizontal tail plane which is furthest away from the fuselage of the aircraft such that the two outer movable parts are located on opposite sides of the vertical tail plane,

wherein both the inner fixed part and the outer movable parts are subjected to a flow coming from the engines when the engines are in use.

2. The aircraft with rear mounted engines, according to claim 1 , wherein the engines are attached to a top surface of the horizontal tail plane via pylons.

3. The aircraft with rear mounted engines, according to claim 1 , wherein the vertical tail plane is in a forward position with respect to the horizontal tail plane.

4. The aircraft with rear mounted engines, according to claim 1 , wherein the inner part of the horizontal tail plane is attached to the fuselage without cutouts in the fuselage.

5. The aircraft with rear mounted engines, according to claim 1 , wherein the engines are ultra high bypass ratio engines.

6. The aircraft with rear mounted engines, according to claim 1 , wherein the engines are propeller engines.

7. The aircraft with rear mounted engines, according to claim 1 , wherein the engines are contra rotating open rotor engines.

8. The aircraft with rear mounted engines, according to claim 1 , wherein the outer movable parts of the horizontal tail plane are moved via actuators.

9. The aircraft with rear mounted engines, according to claim 1 , wherein the elevator of the fixed part of the horizontal tail plane is moved via actuators.

10. The aircraft with rear mounted engines, according claim 1 , wherein a gap between the inner part and the outer parts of the horizontal tail plane is covered by a fairing embedded in nacelles of the engines.

11. The aircraft with rear mounted engines, according to claim 1 , wherein the outer movable parts are rotatable around a shaft protruding from the inner part.

12. The aircraft with rear mounted engines, according to claim 11 , wherein the shaft is perpendicular to the fuselage.

13. An aircraft with rear mounted engines, comprising:
a vertical tail plane, and
a horizontal tail plane,
wherein the engines are mounted on top of the horizontal tail plane,
wherein the horizontal tail plane comprises:
an inner fixed part attached to a fuselage of the aircraft, the inner fixed part comprising an elevator, and
two outer movable parts, each one of the outer movable parts being located at each side end of the horizontal tail plane which is furthest away from the fuselage of the aircraft,

wherein both the inner fixed part and the outer movable parts are subjected to a flow coming from the engines when the engines are in use, and,
wherein a gap between the inner part and the outer parts of the horizontal tail plane is covered by a fairing embedded in nacelles of the engines.

14. The aircraft with rear mounted engines, according to claim 13 , wherein the engines are attached to a top surface of the horizontal tail plane via pylons.

15. The aircraft with rear mounted engines, according to claim 13 , wherein the vertical tail plane is in a forward position with respect to the horizontal tail plane.

16. The aircraft with rear mounted engines, according to claim 13 , wherein the inner part of the horizontal tail plane is attached to the fuselage without cutouts in the fuselage.

17. The aircraft with rear mounted engines, according to claim 13 , wherein the outer movable parts of the horizontal tail plane are moved via actuators.

18. The aircraft with rear mounted engines, according to claim 13 , wherein the elevator of the fixed part of the horizontal tail plane is moved via actuators.

19. The aircraft with rear mounted engines, according to claim 13 , wherein the outer movable parts are rotatable around a shaft protruding from the inner part.

20. The aircraft with rear mounted engines, according to claim 19 , wherein the shaft is perpendicular to the fuselage.
