Cheers Cyrus, I'll look into that. I used the Rocksim app linked above, and found a model of a Saturn V, and that uses a Cd value of about 0.95. Once I've coded the model, I'll try running it and see if I get sensible numbers out of it. I'm only modelling the rocket up to 68km, which is the...

Thanks for the information people, this is all useful stuff. Do you not think it's really viable then to use a constant value of Cd? This is a rather basic model, and many assumptions are made, such as fixed control surfaces, thrust, and the rocket is traveling vertically. We haven't really...

Thanks, that looks useful. That thread doesn't seem to show any specific values for the drag coefficient though.

Hi, just found these forums, and they look very useful. I'm a second year Aerospace Engineering student, and as part of a project I'm modelling the first stage of a Saturn V rocket. I'm using a linear and non-linear model, and have all the equations sorted out. The only problem is I can't...
