- 俄羅斯科學(xué)院西伯利亞分院理論與應用力學(xué)研究所新研制的AT-303風(fēng)洞于1999年開(kāi)始投入使用。 由于具有較高的駐點(diǎn)壓力,AT-303能夠模擬飛行器再入時(shí)的真實(shí)Reynolds數,其Mach數范圍為8~20。The new wind tunnel AT-303 was commissioned in the Institute of Theoretical and Applied Mechanics in 1999.Owing to the high level of stagnation pressure,AT-303 is able to duplicate realistic flight Reynolds number values of re-entry vehicles,within the Mach number range of 8 to 20.In the frame of an ISTC project conducted by ITAM in collaboration with ESTEC and EADS-ST,aerodynamic investigations of different aerospace vehicles have been performed in the AT-303 wind tunnel.
