Trans-Sonic Rocket - F-13TS
I'm still a rocket amateur but I'm building most from scratch. I have two other rockets to finish first, but one of my future projects is to create a very simple trans-sonic or super-sonic rocket powered by the Estes G motor (which I can get at my local Hobby Lobby).
1. What is the best nosecone shape for trans-sonic or super-sonic speed?
2. I plan to use a BT-55 (the heavy duty version) paper tube for minimum diameter with 3 small fiberglass reinforced balsa fins going through the tube and epoxied to the motor tube.
Now I know that at trans-sonic and sonic speeds the CP moves upward negating the already small fins. How do I combat this without adding too much drag?
3. Also, is there a proven fin shape for this?
