Abstract

For modern launch vehicle with under-calibre space nose parts, such as Sous, Arian, GSL-S, Atlas ets, aerodynamic characteristics are examinated in complex conditions of flow with transonic flight.
Aerodynamic features and critical regimes have been found by computation fluid dynamic methods of TSNIIMash, which can cause baffting of launch vehicle and its parts, and unsteady load to resonance phenomenon of flight loop (control). 
The methods of solution complex tasks of flight dynamic, unsteady dynamic and flight control of launch vehicle have been developed, which help complex analisys can be continue of resonance phenomenon. The metheds have been founf for prevention of  high level of pressure pulsations.
