Long-range aircraft with high forward speed in cruising flight

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 in a vertical direction (Z) from a low portion to a high portion, the high portion being disposed above the low portion;
• fixed wings secured to the fuselage;
• a rotary wing above the fuselage;
• at least two propellers for enhancing advance of the aircraft;
• and
• a power plant suitable for driving the rotary wing and the propellers into rotation;
• wherein the fixed wings comprise a front wing extending transversely from the high portion of the front portion of the fuselage and a rear wing extending transversely from the low portion of the rear portion of the fuselage, the 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) opposite the first front transverse direction, at least one of the propellers being mounted on the first front half-wing and at least one of the propellers being mounted on the second front half-wing, the rotary wing being arranged above a central portion of the fuselage so that the axis of rotation (AX) of a rotor of the rotary wing lies between the front and rear wings.
