<p>The invention relates to a hybrid helicopter (1) comprising on the one hand an airframe with a fuselage (2) and a lift surface (3) as well as stabilising surfaces (30, 35, 40) and, on the other hand, a kinematic chain including: a mechanical interconnection system (15) between, on the one hand, a rotor (10) having a radius (R) with a control of the collective pitch and cyclic pitch of the blades (11) of said rotor and, on the other hand, at least one propeller (6) with a control of the collective pitch and cyclic pitch of the blades of said propeller (6), and at least one turboshaft engine (5) driving the mechanical interconnection system (15). The invention is characterised in that the output rotation speeds of at least one of said turboshaft engines (5), of at least one of said propellers (6) of said rotor (10) and of said mechanical interconnection system (15) are proportional between them, the proportionality ratio being constant.</p> |
