LOAD-BEARING STRUCTURE FOR AERODYNAMIC SURFACE Russian patent published in 1999 - IPC

FIELD: construction of aircraft aerodynamic surfaces. SUBSTANCE: load-bearing structure consists of at least two spars, several ribs and skins. Skins and ribs are divided into several parts in way of chord of profile. Load-bearing structure is formed from several box-shaped structural members each of which consists of spar, two members of skin and several members of ribs. During assembly, each subsequent structural member enters previous one between projecting edges of members of skins. Length and number of parts of ribs of structural member are independent on length and number of parts of ribs of previous structural member. EFFECT: ease of mounting aerodynamic surface having insignificant thickness and rather large chord of profile. 2 cl, 9 dwg
