Abstract
A combustion apparatus including a structural jacket, a forward liner, and an aft liner, and an associated method of constructing the same are provided. The structural jacket defines a passage including a first end, a second end, and a neck. The neck is positioned between and separates the first and second ends of the passage. The forward liner is positioned within the first end of the passage and has a throat fitted within the neck of the passage. The aft liner is positioned within the second end of the passage and has an upstream potion abutting the throat of the forward liner. The forward and aft liners are brazed together, and are bonded to the passage of the structural jacket, to form a longitudinal combustion chamber so that combustion of the propellant is contained and directed through the combustion chamber from the forward liner to the aft liner.
