摘要: This paper discusses the Space Shuttle Lift-Off CFD model developed for potential Lift-Off Debris transport for return-to-flight. The Lift-Off portion of the flight is defined as the time starting with Tanking of propellants until 'Tower Clear', approximately T0+ 6 seconds...
One such dispersion is the change in the wind from the last measured balloon to launch time. This process is started in the hours before launch and is repeated several times as the launch count proceeds. Should the trajectory design not meet all constraint criteria, Shuttle would be No-Go ...
