Additional Information
In 1943, TSAGI continued intensive experimental research to further improve the aerodynamics of the La-5FN. At the same time, the designers improved their aircraft. As a result, at the beginning of 1944, a new La-7 fighter was put to the test. It was characterized by a lightweight design (finally, and aircraft La appeared metal spars), reinforced weapons and better aerodynamic properties. To raise the flight data of the aircraft in two ways: by reducing the weight of the airframe and improving aerodynamics. Lavochkin also managed to reduce the weight of the La-5FN last series by about 100 kg by replacing the wooden power set of the wing with metal, and the structural strength at the same time remained at the same level. Due to the supply of lend-lease and the establishment of production in the depths of the USSR, the situation with aluminum was facilitated. Replacement of wooden structures with metal - a large reserve of mass savings. One replacement of wooden wing spars on duralumin with steel shelves reduced weight by 100 kg. I Must say that by this time in the design of the glider is no longer Delta-wood - due to lack of resin from its design gradually replaced the usual pine and birch. Drawings of metal wing spars and center wing were developed in the summer of 1943 in Nizhny Tagil at the plant № 381 under the leadership of chief designer P. D. Grushin - later an outstanding designer of anti-aircraft missiles.
