A parachute is used for model rocket recovery most often in small to medium size model rockets, but can be used with larger rocket models given the size of the parachute greatly increases with the size of the rocket. It uses the ejection charge of the model rocket engine to deploy, or push out, the parachute. Typically, a ball or mass of fireproof paper or material is inserted into the body before the parachute. This allows the ejection charge to propel the fire-proof material, parachute, and nose cone without damaging the recovery equipment. Air resistance slows the rocket's fall, ending (hopefully) in a smooth, controlled and gentle landing. Care must be taken to compensate for wind, as many parachute recovered rockets descend rather slowly, allowing any slight wind to carry the model rocket far away from the intended landing zone.
