ONE-PIECE COMPOSITE MULTI-CELLULAR BOX-LIKE PANEL

摘要

FIELD: process engineering. ^ SUBSTANCE: invention relates to structural elements of aircraft. Proposed panel comprises jacket (1), multiple omega-like stiffness elements (3) and omega-like element (5) covering said stiffness elements (3). Element (5) is connected with elements (3) in superimposed parts in compliances with omega-like shape of elements. Note here that multi-cellular box-like structure is formed with 2n - 1 cells where n is the number of stiffness elements (3). Said panel is formed from separate part with no coverings. Its features high torsional and bending strength and is suitable for weight- and size-constricted structural elements. ^ EFFECT: simplified mounting and reduced number of components. ^ 2 cl, 2 dwg
