Abstract
A rocket motor expansion cone extension skirt of the combustion gas deployable type is purposely delayed in its deployment by an erodable barrier in the motor's expansion cone upstream of the extension and which diverts combustion gas away from the skirt to prevent its deployment. The barrier is eroded away by the gases after a brief predetermined period of time long enough to permit the rocket motor to clear other structures in a situation such as may occur during vehicle stage separation, after which time deployment of the skirt occurs.
