COMBUSTOR OF A LIQUID PROPELLENT MOTOR

摘要

A combustor (2) for a liquid propellent motor (1) has an elongated hollow tubular casing (4) having an inner wall (12) delimiting a combustion chamber (8) for the liquid propellent and an outlet nozzle (11) for the combustion products, and an outer wall (13), both being coaxial to an axis (3) of the casing; the inner (12) and outer (13) walls being spaced apart from each other in radial direction and delimiting at least one guiding conduit (14) of a cooling fluid therebetween; a plurality of bar-shaped elements (22) extending into the guiding conduit (14), which form a grid (23) for perturbing the cooling fluid, stiffening the casing (4) and increasing the heat exchange surface; the grid (23) being part of a body made in one piece and of a single material along with the inner (12) and outer (13) walls.
