Abstract
A method of producing a rocket thrust chamber in which cooling tubes are positioned within a structural jacket to form a tube bundle, and a liner is positioned within the tube bundle thereby sandwiching the tubes between the jacket and the liner. The tubes are then subjected to high internal pressure and inflated while the liner is simultaneously subjected to the same high pressure, thereby forcing the tubes into intimate contact with adjacent tubes, the liner and the jacket. The tubes, liner and jacket are then subjected to ultrasonic vibrations to bond the tubes and jacket into an integral structure.
