Question 155

How does the use of sticks and fins stabilize rockets?
Sticks and fins both shift a rocket's center of aerodynamic pressure (center of drag) toward the tail of the rocket and behind the rocket's center of mass. As a result, the tail of the rocket normally remains at the rear during flight. The passing air twists the tail of the rocket until it's at the rear of the moving object.
