<p>The invention concerns the design of the helicopter body central structure enabling functional use of the body internal volumes for installing the control unit, the helicopter systems and for arranging loads in the cargo hold. The helicopter body consists of a central part (1) whereto are linked a front part (2) and a rear part (3) and a landing gear, and whereof the central part (1) consists of two side panels (6 and 7), a top panel (17), lower surfaces (14 and 15), a rear panel (13) and a front panel (11) mutually assembled and forming a polyhedral structure. The invention is characterised in that the polyhedron front panel (11) consists of front surfaces (8, 9), linked by surfaces (10) and the configuration of said front surfaces (8, 9, 10) forms a rectangular cavity (12) passing through the whole height of the front panel (11), whereas the polyhedron top panel (17) is positioned perpendicularly to the main rotor axis (18). The floor (5) constitutes an element common to the front part (2), the rear part (3) and the central part (1); said floor is horizontal in the front part (2) and curves at angle (α) in the central part (1) and is extended towards the body rear part (3).</p> |
