![]() ![]() What is the most aerodynamic shape supersonic?įor supersonic speed, the most aerodynamic shape is Sears–Haack body. This allows interference drag (drag caused by interference of the airflow over the body and fins at the junction) to be reduced by 25 percent. Three fins are best when designing a high performance, low drag rocket. So the question becomes - 3 or 4 fins? Nearly all my rockets had four fins. Are 3 or 4 fins better on a bottle rocket? Rockets with a larger diameter have more drag because there is more air being pushed out of the way. What is the best shape for a rocket and why?Īt supersonic speeds (faster than the speed of sound), the best shape is a narrower and sharper point.
