What are some fundamental differences between composite propellant model rocket motors and black powder model rocket motors?
• Composite propellant has up to 3 times the power of black powder by weight • Composite propellant model rocket motors are usually “core burning” and are ignited at the “head end” of the propellant grain instead of the nozzle end • A reinforced plastic case is used in a composite model rocket motor instead of a wound paper case • The composite model rocket motor nozzle is reinforced plastic instead of pressed clay • The bulkhead end of the composite model rocket motor is cast epoxy or molded plastic • Composite model rocket motors are much louder and more spectacular than black powder model rocket motors • Rockets powered by composite model rocket motors will fly much higher and faster than with black powder model rocket motors • The high energy of composite propellant enables the manufacture of model rocket motors that are the same size as black powder model rocket motors but with about twice the power.
