FIELD: test equipment.
SUBSTANCE: invention relates to ground tests of aircraft (AC) elements, namely to methods of reproducing aerodynamic thermal action on head (fairing) of missile under ground conditions. Essence is that reproduction of aerodynamic force and thermal action is conducted and temperature measurement. Force impact from loading elements to cowl outer surface is transferred to n-th number of rods (uniformly distributed over the surface of the structure), passing through wall of current-conducting and heat-insulating shell, wherein sum of areas of cross section rods is much less than heated surface, and density of distribution of rods on surface of structure is selected so that to exclude mechanical stress concentrators in interaction of rods with external surface of structure.
EFFECT: complete reproduction of aerodynamic effect (heat and power) on cowl outer surface of non-metallic materials at ground development of design.
