8.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.
10.According to the occurrence and maintenance of torrential rain relating closely to moisture convergence increment in low layer of troposphere, a new type of divergence equation is applied to analyse physical mechanics of the maintenance of torrential rain process in the east of Sichuan basin from 2 to 6 July, 1989.
