Thrust Oscillation Issue Threatens Ares I Design, Aviation Week
"George" wrote in message .. . "Jeff Findley" wrote in message ... "George" wrote in message .. . I can understand your frustration, but your solution really isn't a solution, is it? Just a criticism, right? NASA isn't going to change their plan for you or I, so what solution do you have for the vibration problem that they anticipate will occur with this vehicle? That's the question. If you don't have a problem to solve, there isn't a problem, is there? Why spend billions developing Ares I to do what you could do with an EELV Heavy launch? Why tie NASA to its own home grown launch architecture for decades when the private sector has several start-ups which show some promise of lowering launch costs in far less time than that? I never wanted NASA to start developing *any* shuttle derived launch system. They'll spend several billions of dollars developing a system that's expensive to maintain and lock themselves out of the possibility of using something cheaper in the future. I don't disagree with you. That said, the question remains. The question has no answer. NASA doesn't have a solution. Ares I and Orion are both overweight. As the old saying goes, you can't make a silk purse out of a sow's ear. NASA's approach of defining the lunar architecture first, then trying to make shuttle derived hardware fit is simply awful. All of this seems to be an attempt to protect a lot of shuttle jobs rather than attempting to define an architecture based on launch vehicles that actually exist.
