Can model rockets be flown more than once?
Yes, all model rockets are equipped with some kind of recovery device to bring the rocket back to earth in a safe fashion. Some small lightweight models may use a streamer made of crepe paper, nylon or Mylar foil. This is ejected from the rocket at the top of its flight and creates drag, slowing the rockets descent, and making it easier to spot in the sky. The most common recovery device is a parachute, made of plastic, mylar, or ripstop nylon, which is deployed at the top of the flight (apogee), by a small explosive charge in the motor. A flameproof tissue called recovery wadding is placed around the parachute to prevent the hot gases from the ejection charge damaging the ‘chute. Once the rocket is back on the ground, it is a simple matter to repack the parachute and wadding, replace the spent motor, and get back to the launch pad. What makes rockets fly? Newton’s third law! Model rockets are powered by miniature rocket motors. The smaller models use a disposable motor which has black
