    摘要: In a combustion chamber (5) of a liquid propellant engine (1), a combustible liquid and an oxidising mixture are fed by means of two different independent and mechanically separate feed pumps (12),(27) and driven by respective turbines (16),(32) which are also independent and mechanically separate from each other; the oxidising mixture generated by a combustible liquid pre-burner (22) passing through one of the turbines (32); and the heated combustible liquid passing through the other turbine (16) before it is supplied to the combustion chamber (5); the oxidising mixture, after having passed through the respective turbine (32), flows into the combustion chamber (5) via an injection plate (6).

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