ABSTRACT:
A helicopter deck comprises a supporting main frame (1, 2) which at least comprises a preferably polygonal circumferential frame (1), possibly connected with intermediate carrying beams (2), the main frame (1, 2) forming a supporting frame for the actual deck consisting of elongate, mutually "semi-rigidly" (mortice/tenon) connected deck elements (3), e.g. in the form of extruded aluminium profiles. One has aimed at providing a distribution of point loads (from helicopter wheels) from one loaded deck element (3) across the same and the adjacent deck elements (3), thereby giving rise to helicopter deck weight reductions. To this end, at least most of the deck elements (3) are connected with at least one underlying, lateral, load distributing beam (5) which is freely suspended and, thus, not connected with or supported on the main frame (1, 2).
