I-310 (S-1, S-2, S-3) by A.I.Mikoyan and M.I.Gurevich
Prototype of the MiG-15. Aircraft differed from the MiG-9 family by swept wing (with fences) and tail, exhaust tube extending to the very end of fuselage, single engine, airbrakes etc. I-310 (S) marked a new era in Soviet jet aircraft design.
First flight was performed by pilot V.N.Yuganov on December 30, 1947. Overall performance was satisfactory, but thrust losses were too hight. Fuselage was shortened, exhaust tube redesigned. Sweep angle of the tail surfaces was increased, together with changes in the wing construction.
Prototypes were presented for State Trials in May-July 1948.
The S-1 and S-2 were powered by Rolls-Royce Nene-1 and S-3 - by Nene-2.
Aircraft was in tight contest with Lavochkin La-15. Both aircraft were built in series and saw service, but the La-15 lost competition at last. Another fighter in the race was Yakovlev's Yak-30, which was little late (first flown on September 8, 1948) and failed to show advantages over other two.
