Abstract

An aircraft includes a structure exhibiting a median plane XZ and including a fuselage, a fixed vertical stabilizer at the rear of the fuselage, an adjustable horizontal stabilizer rotatably mounted about a horizontal axis on a first section of the structure, and extending on either side of the median plane XZ, and at the rear, two elevators mounted rotatably about a horizontal axis on a second section of the structure on either side of the median plane XZ independently of the adjustable horizontal stabilizer. In an aircraft of this kind, the elevators no longer have any impact on the adjustable horizontal stabilizer, which allows, among other things, the dimensions of the adjustable horizontal stabilizer, and also of the actuator operating them, to be reduced.

First claim

The invention claimed is:

1. An aircraft comprising:
a structure having a median plane (XZ) and comprising:
a fuselage;
a fixed vertical stabilizer at the rear of the fuselage;

an adjustable horizontal stabilizer rotatably mounted about a horizontal axis on a first section of the structure, and extending on either side of the median plane (XZ), and not including an elevator on a trailing edge of the adjustable horizontal stabilizer;
a first pair of elevators mounted rotatably about a horizontal axis on a second section of the structure on either side of the median plane (XZ) independently of the adjustable horizontal stabilizer,

wherein the first section of the structure is a rear section of the fuselage, and
wherein the second section of the structure is the vertical stabilizer.

2. The aircraft as claimed in claim 1 , wherein the vertical stabilizer comprises a leading edge and a trailing edge and the structure comprises on the inside of the vertical stabilizer:
a front longeron extending along the leading edge;
a rear longeron extending along the trailing edge;
an intermediate longeron fixed between the front longeron and the rear longeron and on which each of the first and second elevators is rotatably mounted, and
for each of the first and second elevators, at least one actuator mounted in an articulated manner between the intermediate longeron and the elevator.
