Abstract
A compound helicopter comprising a fuselage, a main rotor arranged at an upper fuselage section of the fuselage for generating lift in operation, two cantilever wings arranged within a main rotor disc defined by the main rotor, two lateral booms respectively connected to the two cantilever wings, and a pusher propeller arranged within the main rotor disc. The two cantilever wings are attached to a rear fuselage section of the fuselage and laterally extending on each side of the fuselage. The lateral booms are extending rearwardly beyond a rear fuselage end of the fuselage in a longitudinal direction. The pusher propeller for generating forward thrust in operation is attached to the rear fuselage end between the two lateral booms.
Claims15
A compound helicopter comprising:
- a fuselage that extends in a longitudinal direction from a front fuselage section through a center fuselage section and a rear fuselage section to a rear fuselage end, and in a vertical direction from a lower fuselage section to an upper fuselage section;
- a main rotor that is arranged at the upper fuselage section and at least adapted for generating lift in operation, the main rotor comprising at least two rotor blades that form a main rotor disc during rotation of the main rotor;
- at least two cantilever wings that are completely arranged within the main rotor disc and attached to the rear fuselage section, wherein a first cantilever wing of the at least two cantilever wings laterally extends from the fuselage at a port side, and a second cantilever wing of the at least two cantilever wings laterally extends from the fuselage at a starboard side;
- a first lateral boom that is connected to the first cantilever wing, and a second lateral boom that is connected to the second cantilever wing, the first and second lateral booms extending rearwardly beyond the rear fuselage end in the longitudinal direction, and
- a pusher propeller that is arranged within the main rotor disc between the first and second lateral booms, attached to the rear fuselage end, and at least adapted for generating forward thrust in operation.
