LONG-RANGE AIRCRAFT WITH HIGH FORWARD SPEED IN CRUISING FLIGHT
First Claim
1. An aircraft with a long-range and with high forward speed, the aircraft comprising:
- an airframe provided with a fuselage extending along a longitudinal direction (X) from a front portion towards a rear portion and passing via a central portion, and in a vertical direction (Z) from a low portion to a high portion;
fixed wings secured to the fuselage;
a rotary wing above said fuselage;
at least two propellers for enhancing advance of said aircraft; and
a power plant suitable for driving said rotary wing and said propellers into rotation;
wherein said fixed wings comprise a front wing arranged in the high portion of the front portion of the fuselage and a rear wing arranged in the rear portion of said fuselage, said front and rear wings each extending transversely on either side of the fuselage, said front wing having a first front half-wing extending transversely from the fuselage in a first front traverse direction (Y1) and a second front half-wing extending transversely from the fuselage in a second front transverse direction (Y2), at least one of said propellers being mounted on said first front half-wing and at least one of said propellers being mounted on said second front half-wing (21″
), said rotary wing being arranged in the central portion so that the axis of rotation (AX) of a rotor of said rotary wing lies between said front and rear wings.
