Chapter 15. Minimum-Diameter Rockets

You saw in Chapter 13 that drag is one of the three forces that control how high and fast a stable rocket will travel; the others being the force of gravity acting on the mass of the rocket, and the thrust of the motor. You also saw that most of the drag on a rocket is proportional to the area the rocket presents in the direction of travel. That means one of the easiest ways to make a rocket go faster and higher is to slim it down. And that’s what Hebe does.
