Aluminum alloys have been being the basic structural material in the world aircraft industry for more than 90 years. Many Russian aluminum alloys are developed under the guidance of academician I. N. Fridlyander. Every alloy was exposed to the hard work, connected with large part of investigations of structure and phase composition and improvement of aviation structures. The V95 (В95), V95pch/och (В95пч/оч), V96ts-3pch (В96ц-3пч), V93 (В93) and 1933 alloys of Al – Zn – Cu – Mg alloying system have been also developed under the guidance of I. N. Fridlyander. These alloys are used as structural elements of military and civil assignment aircrafts. 1933 aluminum alloy demonstrates high strength and high fracture toughness. It is the base material of internal power set (frames, fitting, beams, longerons) of glider of the airplanes SSJ-100, Yak-42, An-148, An-225, etc. Heat resistant aluminum alloys (AK4-1ch (Ак4-1ч), D20 (Д20), 1151) were developed and successfully applied to details and elements of glider of supersonic warfare airplanes. The effect of hardening of Al – Mg – Li alloys heat treatment is discovered under the guidance of I. N. Fridlyander. Each weight percent of lithium (as addition in aluminum) reduces its density by 3% and extends elastic modulus by 6%. On the basis of this investigation there was developed the lightest 1420 aluminum alloy, which led to obtaining of new generation of aluminumlithium alloys (1441, V-1461 (В-1461), V-1469 (В-1469)). Application of these alloys led to reduction of riveted constructions mass to 12%, and welded constructions mass to 24%. Aluminum alloys of different alloying systems, developed by academician I. N. Fridlyander, made it possible to create the large part of warfare, civil and transporting aircrafts, competitive to the world level. I. N. Fridlyander devoted 70 years of his life to the service of science and reached phenomenal results.
