Abstract
An aircraft comprising two half-wings extending to either side of an airframe. The aircraft comprises at least one propeller arranged in the rear part of the airframe. The aircraft comprises a rotary wing provided with two synchronized counter-rotating rotors carried respectively by the half-wings. The aircraft comprises a power plant comprising at least one engine and a mechanical interconnection system connecting the power plant permanently to the rotors except in the event of failure and during training, and to the at least one propeller.
Claims20
An aircraft comprising:
- an airframe extending longitudinally in an anteroposterior plane from a rear part towards a nose;
- a rotary wing provided with two counter-rotating rotors;
- at least one propeller arranged in the rear part of the airframe;
- a power plant comprising at least one engine;
- a mechanical interconnection system connecting the power plant permanently to the rotors except in the event of failure and during training, and the mechanical interconnection system connecting the power plant to the at least one propeller permanently or at the request of a human pilot or an autopilot with an inhibitor;
- and
- two half-wings extending on either side of the airframe,
- wherein the two rotors are carried respectively by the half-wings and arranged respectively above the half-wings, the two rotors being synchronized, the at least one propeller comprising two propellers arranged to either side of the anteroposterior plane, the rear part comprising a stabilizer assembly, the stabilizer assembly being Y-shaped having a central branch and two lateral branches, the two propellers being carried respectively by the two lateral branches.
