T O P I C R E V I E WhlbjrWatching the Spacecraft Films Apollo 7 DVD's, I wondered how the service module thrusters can take the aerodynamic pressure (slipstream) during the launch period in the lower atmosphere? I'm especially wondering how the forward and side-facing thruster "bells" can take this force? How did the experts figure that one out? Thanks for your information.Harvey[Edited by hlbjr (December 09, 2006).]sts205cdrThe conical shape of the CM above caused the high-pressure airstream to move away from the sides of the SM. --JohnLCDR Scott SchneeweisActually its mitigated by the design of the thrusters themselves. There were a number of boilerplate tests which included as a specific objective, understanding how the spacecraft reacted to the launch environment. Boilerplates 15, 26 and 9 (missions SA-7, 8 and 10 respectively) included either simulated or actual RCS packages which were instrumentated with thermal couples and accelerometers to measure temperature and vibration; the testing demonstrated the quad's were able to weather stresses associated with launch vehicle transit through maximum dynamic pressure.------------------Scott Schneeweis URL http://www.SPACEAHOLIC.com/
