  • ROCKET ENGINE COMBUSTION CHAMBER
    Publication number: 20080078164
    Abstract: An improved engine construction is provided. The engine construction comprises a combustion chamber, a smooth wall nozzle, and a transition zone between the chamber and the smooth wall nozzle. The transition zone has a coolant system which includes a manifold formed from a non-copper material through which a coolant flows. In a high heat transfer embodiment, the transition zone includes an additional manifold formed from a copper based material.
    Type: Application

  • Rotor assembly
    Patent number: 4344740
    Abstract: The present invention provides an improved sideplate of the type adhered to the side of a rotor disk for the retention of rotor blades and for blocking the leakage of working medium gases across the rotor disk. The elimination of retaining bolts and rivets is sought.In one effective embodiment of the present invention, the sideplate is adhered to the disk at a bayonet type joint. The sideplate is elastically deformable to enable assembly of the sideplate onto the disk with abutting surfaces of the disk and sideplate in interference engagement at release. The side surface of the disk is tapered in cross section geometry to accommodate deformation of the sideplate.

  • Adjustable pintle spray manifold assembly
    Patent number: 4058263
    Abstract: An adjustable fluid flow and spray control for use in conjunction with a manifold. The rate of flow of a fluid, and the rate of spraying of the fluid, are controlled by moving a pintle, instead of further deforming the manifold, as is conventionally done.
