I have always used ThrustCurve.org as a guest, but yesterday I registered and started saving my rockets. In order to save a rocket, to have to enter the drag coefficient. So I have two questions?
Is that a flat value based on the size/shape of the rocket? I always thought it changed based on windspeed, altitude, etc.
If the above is a "yes," then how do you calculate it?
Okay, third question, anyone got a spreadsheet or web site that will do it?
Thanks.
