A first construction module for the construction of a modular landing platform for vertical landing aircraft, said module comprising:
- a module body having a resting wall configured to be placed on a supporting surface, a landing wall opposite to the resting wall and adapted to come into contact with said aircraft during landing, first and second interconnecting walls which are opposite to each other and interposed between the resting wall and the landing wall;
- first and second coupling portions which protrude laterally outwards from the first interconnecting wall, the first and second coupling portions being of a different type and mutually spaced apart;
- a third and fourth coupling portions protruding laterally outwards from the second interconnecting wall, the third and fourth coupling portions being of a different type and spaced apart;
- wherein the third and fourth coupling portions of said first module are configured to couple respectively with the first and second coupling portions of a second module of identical construction to said first module;
- wherein the first coupling portion of said second module and the third coupling portion of said first module are configured to be couplable with each other through relative rotation of said second module with respect to said first module, and wherein the second coupling portion of said second module and the fourth coupling portion of said first module comprise male-female coupling portions;
- wherein the male coupling portion and the female coupling portion of said male-female coupling portions respectively comprise a longitudinal rib and a longitudinal groove adapted to receive said rib, said female coupling portion comprising a first longitudinal fin;
- wherein in a cross-section of said first and second modules, either the first coupling portion of said second module or the third coupling portion of said first module comprises at least one coupling tooth and the other either first coupling portion of said second module or third coupling portion of said first module comprises at least one coupling cavity adapted to receive said coupling tooth;
- wherein said female coupling portion comprises a second longitudinal fin, wherein said first and second longitudinal fins delimit said longitudinal groove, said second longitudinal fin being an elastically flexible fin configured to be deformed elastically and to apply pressure on said longitudinal rib to retain said rib when said male-female portions are coupled to each other;
- wherein in a cross-section of said first and second modules (10B,10B), both the first coupling portion of said second module and the third coupling portion of said first module comprise a pair of coupling teeth and a pair of coupling cavities, wherein when the first coupling portion of said second module and the third coupling portion of said first module are coupled to each other, the coupling cavity pair of said first coupling portion of said second module is adapted to receive the coupling tooth pair of said third coupling portion of said first module and, vice versa, the coupling cavity pair of the third coupling portion of said first module is adapted to receive the coupling tooth pair of the first coupling portion of said second module to prevent lateral separation of said first and second modules when said modules are coupled to each other.
