STABLE-SHAPE STRUCTURAL PLATFORM FROM COMPOSITE MATERIAL (VERSIONS) Russian patent published in 2012 - IPC B64G1/22 B32B33/00 

FIELD: transport.

SUBSTANCE: invention relates to aerospace engineering, particularly, to production of platforms including those located outside the spaceship. In compliance with first version, platform is composed of composite spatially closed structure made by two panels with cutouts, side walls and end flanges. Cutouts of second panel are located asymmetrically relative to those of the first panel. Second panel surface area is smaller than that the first panel. End flanges comprise hinge assemblies and are made from metallic alloy. Second panel is thicker than the first one, or elasticity modulus of second panel exceeds that of the first one at identical thermal linear expansion factors approximating to zero. In compliance with second version, platform is composed of composite spatially closed structure made by two panels with cutouts, side walls and end flanges. Cutouts of second panel are located asymmetrically relative to those of the first panel. Second panel surface area is smaller than that the first panel. End flanges comprise hinge assemblies and are made from metallic alloy. First panel thermal linear expansion factor approximates to zero while that of second panel is negative at equal thickness and elasticity modulus.

EFFECT: decreased spatial thermal deformations.
