专利汇可以提供Coaxial injector for reaction motors专利检索，专利查询，专利分析的服务。并且A coaxial injector particularly suited for use in mixing liquid propellants within combustion chambers of reaction motors, characterized by a first annular orifice, of a fixed dimension, adapted to deliver liquid oxidizer in an outwardly diverging conical sheet circumscribed by a second annular orifice, also of a fixed dimension, adapted to deliver an outwardly converging conical sheet of liquid fuel, whereby the sheets are caused to experience momentum exchange at an annular intersection for thereby developing a homogeneous mixture sheathed within a layer of a fuel-rich mixture for cooling the walls of the associated combustion chamber, a feature of the injector being an integration of injector components into an all-welded, unitary structure having empirically established propellant mixing characteristics.，下面是Coaxial injector for reaction motors专利的具体信息内容。
1. A single-element coaxial injector for reaction motors comprising: A. an injector plate adapted to be mounted within the wall of a combustion chamber of a reaction motor; B. means defining within said plate a bore terminating in a first outwardly flared segment for communicating with said combustion chamber; C. a first metering plug seated in said bore and welded to said injector plate for thereby defining a permanently configured, annular fuel injection orifice for delivering a converging conical stream of fuel; D. means defining an axial bore extending through said first metering plug terminating in an outwardly flared conical segment concentrically related with said fuel injection orifice; and E. a second metering plug extended into said axial bore and welded to said first metering plug defining a permanently configured annular oxidizer discharge orifice concentrically related to said annular fuel injection orifice for delivering a diverging conical stream of oxidizer intercepting the conical stream of fuel.
2. A coaxial injector for reaction motors comprising: A. an injector plate including means defining therein an outwardly flared injection cone; B. means defining a tubular bore extended through said plate in a coaxial relationship with said Injection cone; C. means defining within said tubular bore a fuel metering chamber of an outwardly converging, truncated conical configuration communicating with said injector cone; D. means defining a plurality of fuel passageways communicating with the tubular bore; E. a first elongated metering plug having a cylindrical body and a tapered metering tip disposed within said tubular bore in a manner such that the surface of the tapered tip and the surface of said metering chamber are concentrically related for defining therebetween a fuel injection orifice of an annular configuration for delivering a converging conical sheet of fuel; F. means defining a concentric bore extended through said metering plug and terminating in an oxidizer discharge cone of an outwardly flared, truncated, conical configuration; G. an annular chamber defining a manifold communicating with said oxidizer discharge cone and circumscribing said concentric bore; H. a unitary tubular member defining an oxidizer delivery conduit seated in said concentric bore and terminating in a second elongated metering plug of an outwardly flared, conical configuration having a metering surface radially spaced from the surface of said oxidizer discharge cone and defining therebetween an annular oxidizer discharge orifice for delivering a diverging conical sheet of fluid oxidizer; I. means defining within the tubular member a plurality of radially directed openings extending between said conduit and said annular chamber; and J. a plurality of weld seams integrating the plate, the first metering plug, and the unitary tubular member into a rigid unitary configuration.
3. The injector of claim 2 wherein the position of the metering plug relative to the metering chamber and the tubular member relative to the concentric bore empirically are established for determining the flow characteristics of the fuel injector orifice and the oxidizer discharge orifice.
4. A coaxial injector for liquid propellant reaction motors comprising: A. an injector plate adapted to be mounted on the wall of a combustion chamber within a reaction motor; B. a plate having formed therein means defining an injection cone including a discharge opening and an inlet opening of a reduced diameter coaxially related to said discharge opening; C. a bore extending from said inlet opening through said plate including a conical metering surface defining a first metering chamber adjacent said inlet opening; D. a first metering plug including an axial bore extended therethrough and terminating in an outwardly flared internal surface defining a second metering chamber of a conical configuration, and a conically tapered external surface defining a metering needle, said first metering plug being inserted and positioned within said bore in a manner such that the conically tapered external surface thereof is positioned adjacent the metering surface of the first metering chamber as a fluid under pressure is delivered therebetween, for thereby establishing a first annular orifice having empirically determined flow characteristics; E. a metering shaft having an axial conduit terminating in a plurality of radially directed terminal ports including a terminal protuberance of a conical configuration closing said axial conduit at a point adjacent to said ports and defining a second metering plug seated within the axial bore of said first metering plug in a manner such that the external surface of the second metering plug is related to the outwardly flared internal surface of the first metering plug for defining a fluid passageway therebetween, the axial position of said shaft being achieved concurrently with a delivery of a fluid through the conduit and said fluid passageway for thus establishing an annular discharge orifice having empirically determined flow characteristics; F. means defining a first weld seam coupling said shaft in place within said axial bore, whereby sAid shaft and said first metering plug fixedly are integrated into a unitary configuration; and G. means defining a second weld seam coupling said first metering plug to said plate for thereby fixedly integrating the plate and the metering plugs of said injector into a unitary, single-element coaxial injector.
