NGSS.MS-PS3-3

Used to protect the recovery system from the heat of the ejection charge. Pack wadding between the engine and the recovery system for a distance equal to the one-and- a- half times the diameter of the body tube. Wadding serves as an insulator between the engine and the recovery system and as a gas seal to ensure that the ejection charge works evenly against the recovery system and nose cone.
