Abstract
The present invention discloses a composite material closure as a port cover for a rocket-ramjet engine and a method of transitioning between rocket booster operation and ramjet operation. The composite material closure is made to be coextensive with an insulating lining of the casing of the rocket-ramjet engine. Pyrotechnic charge devices are associated with the composite material closure and ignited to cut there-through and form an opening in the closure for air flow during ramjet operation.
