ROCKET ENGINE COMBUSTION CHAMBER HAVING A NUMBER OF CONFORMAL THROAT SUPPORTS

PROBLEM TO BE SOLVED: To provide a method for manufacturing a rocket engine combustion chamber of reduced weight at low manufacturing cost. SOLUTION: In this method for manufacturing a rocket engine combustion chamber, a cooling fluid liner 10 is formed, and a plurality of cooling fluid channels 12 are formed in an outer surface of it. Two or more inner conformal throat support sections 14 and 16 and two or more outer conformal throat support sections 20 and 22 are formed. The inner conformal throat support sections 14 and 16 are assembled to enclose the outer surface of the cooling fluid liner 10 to form closure. The inner conformal throat support sections 14 and 16 enclose an outer surface of an inner conformal throat jointed at an inner throat seam line 18, and the outer conformal throat support sections 20 and 22 are assembled to enclose an outer conformal throat to cover the inner throat seam line 18 for forming a liner throat support structure, and enclose the liner throat support structure to assemble an inlet manifold 24 and an outlet manifold 24 to compose an HIP structure.
