The simulations here use a balsa bulkhead to represent the weight and drag of those nosecones. RockSim just doesn't allow me to put a nose cone anywhere except the very front of the rocket. It also doesn't allow a transition anywhere except the centerline of the rocket, meaning I can't even use that component to simulate a NC. It does allow those bulkheads, go figure...
For the rest of the components, I've used pretty much what you've described. The wrap is probably not to the exact weight, but it's going to be close. Keep in mind, since the original Orion used cut-down Saturn wraps, a SEMROC kit can simply borrow from the S1B kit and be "keeping in spirit", if not spot-on, with that original Centuri kit. |
