Ray Dunakin con Staging High Power Rockets (Rocketry Educational Series) (English Edition)Black powder rockets can be easily staged by using a booster motor that has no delay and no ejection charge, and by placing the upper stage directly over the booster in close proximity. High Power fliers don’t have it so easy. Not only are higher-energy composite propellants harder to light, they must be lit from the very top of the motor core.
In this booklet Ray Dunnakin walks us through techniques that allow air starting of these high power motors. Once free of the constraint of having to put the upper stage motor directly over the booster, many other configurations can be used. Ray discusses inline (with large separations), parallel and parasite staging, all with multiple motors.
