Or put another way, reducing the body diameter by ½ reduces drag losses to ¼. ![]() The equation for rocket aerodynamic drag was given earlier by Equation 1 (orĮquation 2, for supersonic flight, however, read this note):Ī = frontal area of rocket, where A = ¼ π D 2ĭoubling the diameter (D) of the rocket body increases drag force by a factor of four. This is because drag force (F d) acting against a rocket's upward motion is proportional to the body diameter squared. The diameter of the rocket body has a particularly strong influence on how high a rocket can fly with a given motor. Richard Nakka's Experimental Rocketry Web SiteĪ good starting point in designing a rocket is to decide how big we want our rocket to be, specifically, the body diameter. ![]() Richard Nakka's Experimental Rocketry Site
