History

The thirties and forties

The first national high-strength steel “Chromansil” (30KhGSA) was developed and introduced into practice in aircraft building industry; this steel was ahead of foreign similar products by 25 years, which made it possible to eliminate foreign deliveries of molybdenum and nickel.
The first aluminum alloys of duralumin and magnalium series were developed and mastered up for airframes of all-metal airplanes.
A process of multiple-stage nitriding of large gears for aircraft engine was developed and implemented in the industry.
Aircraft armor for IL-2 strike fighter was developed (Stalin Prize, 1942).

A high-strength wood composite material (impregnated modified wood), a basic structural material for fighters (IL, MiG, LaGG) was developed.
New technologies for making high-strength structural steels in Martin furnaces instead of electric furnaces remaining in the occupied territory were developed and introduced into practice (Stalin Prize, 1943).
The foundations of the multielectrode structural metal corrosion theory were developed.
An original high-productive technology to manufacture riveting wire for combat airplanes was developed and implemented (Stalin Prize, 1944).
Protected fire-proof fiber tanks providing an enhanced survivability of combat airplanes were developed.
Indecipherable, camouflage lacquer-and-paint coatings for combat airplanes were developed.
In 1945 the institute was awarded the Order of Lenin for its contribution to the victory in the Great Patriotic War.
A high-performance technology for combined welding of IL-2 and Yak-7 aircraft structural elements made of tampered steel was developed (Stalin Prize, 1946).
Heat-resistant cladding alloys without cobalt, which was in a very short supply, were developed for aircraft engine valves designed by A. A Mikulin and V. Ya. Klimov (Stalin Prize, 1946).
A monograph “Theory and methods of metal corrosion researches” was published (Stalin Prize, 1946).
A transparent armor for IL-2, Yak-2, Yak-9, La-5, La-7 airplanes was developed; for the first time an idea of composite armor was offered and implemented in the design of this armor (Stalin Prize, 1949).
