Once the war broke out the whole engineering office was evacuated to Moscow. Shahkhatuni worked in the Yakovlev engineering office until 1945. Shahkhatuni carried out the strength calculations for the double-decker glider for air transport armored vehicles and later when Antonov was working in the Novosibirsk aircraft plant in 1946, she led the department which completed the strength calculations for the SChA-1 biplane, the forerunner of the Antonov An-2.

Shahkhatuni become a professor and doctor of technical science and taught at the Kyiv Institute of Civil Aviation Engineers. She continued to work on the calculations for Antonov's airplane designs including among other things invented a welding - bonding process with which the aircraft service life was significantly increased.
