It's probably more akin to "The Dark Knight." It takes a Joker to come up with a bad design like Ares I, and it takes an even bigger Joker to endorse the idea of multiple thrusters which will dampen out the oscillations (while increasing your LOM numbers.) Two-Face is busy telling the public that all is well, even though Ares I first flight keeps slipping to the right of the schedule.<BR/><BR/>In all seriousness, I have to ask about the "1100 pound" figure. Are you saying that 1100 pounds of the existing propellant load is being wasted on thrust vector control? Or will the SRB be stretched to accommodate that extra 1100 pounds? Without a change in moldline, it means another performance hit for a vehicle that already had tight performance margins.Mr. Xhttps://www.blogger.com/profile/08537371901494918449noreply@blogger.com
