ABSTRACT:
This model rocket car carries a U-shaped tube with lower and upper straight segments connected at their front ends by a bight segment. The lower segment of the tube holds a model rocket engine which, upon ignition, first ejects gas out the back end to propel the car forward and after a burning time ejects gas from its front end forward into the tube. The upper segment of the tube holds a folded braking parachute, tethered to the car, which is blown out of the tube by the gas ejected from the front end of the engine and opens behind the car. Flame retardant wadding is in the upper segment of the tube directly in front of the folded parachute.
