Recovery wadding serves a critical role in rocketry by protecting the recovery system—such as the parachute or other deployment devices—from the intense heat generated by the ejection charge during the rocket's recovery phase. When a rocket's ejection charge fires, it expels the recovery system to ensure a safe descent. The heat from the ejection charge is sufficiently high to potentially damage the recovery system material if not properly shielded.

Recovery wadding, typically made of materials that can withstand high temperatures (like flame-resistant tissue or synthetic materials), is placed within the rocket body above the motor and below the recovery system. This layer absorbs the heat, preventing it from reaching the recovery system and allowing it to deploy correctly and without damage. Without wadding, the heat could burn or melt the recovery device, leading to recovery failure and potentially causing the rocket to be lost.

The other options relate to different aspects of rocketry. While enhancing lift, increasing stability, and providing casing are vital functions in their contexts, they do not pertain to the specific role of recovery wadding. Thus, the primary function of recovery wadding is to ensure the safe deployment of the recovery system by shielding it from the heat of the ejection charge.
