MOMENT VS. TIME FOR DIFFERENT BOOSTER ANGLESI order to <strong>com</strong>plete the pitch-up solution, placing the booster in an anglewas tasted. This angle should cause negative moment and by this willcancel the pitch.At the sketch r,R –are distances that changing in time.To examine this solution, graphs of the moment vs. time (while theunfolding of the wings) where plotted for different angles. There is aneed to confront with the change of mass and pressure centers due towings opening.The above graph shows how the moment changes with time at differentangles from to .The conclusion is: when the angle equals the moment's sum is zero,so by placing the booster at this angle there will be no pitch.14
