Abstract
Present combustion liners are used to form combustors in which fuel and air are burned and heat energy is directed to a turbine. The construction of the present combustion liners reduces manufacturing cost by reducing assembly time and processing time. An inner and outer liner portion is formed from a single sheet into a generally cylindrical tube. The tube is formed, by a spin forming operation to include a plurality of generally axial portions being interconnected by a plurality of transition portions. The transition portions have a plurality of openings therein to be used for cooling the combustion liner portions. The transition portions also act as stiffeners to support the generally cylindrical configuration of the tube.
