Development of thermal protection systems is one of the important engineering problems that should be solved at development of reusable space vehicles. Metal panels of thermal protection systems should consist of separate tiles with individual fastening to load-carrying structure of space vehicle, with surface density of not more than 10 kg/m 2 , capable of withstanding multiple long flights and providing temperature lowering from 1100 ºC on the outer wall to 200 ºC on the inner wall. The work shows the results on development of the technology of vacuum diffusion welding of a three-layer honeycomb panel from experimental powder alloy YuIPM-1200. Technological samples of three-layer honeycomb panel were made from this alloy, and their testing was performed in the working temperature range. 7 Ref., 11 Figures.
