ABSTRACT:
A method of producing a tubular structure, such as a rocket thrust chamber, includes positioning cooling tubes about an inner tooling fixture to form a tube bundle, and positioning a segmented outer tooling fixture about the tube bundle thereby sandwiching the tubes between the inner tooling fixture and the outer tooling fixture. The tubes are then pressurized at high temperature and the inner tooling fixture, outer tooling fixture and tube bundle are heated to a temperature at which each of the tubes bonds to adjacent tubes.
