    • A flame holder is provided at a head end of a combustion chamber of a hybrid rocket motor. The flame holder includes a high-temperature casing defining a cavity, and a solid propellant within cavity around or near the injector. The propellant may be provided in an annulus within the casing, such that the flame plume from the burning propellant is substantially parallel to the flow of the oxidizer, or may be generally cylindrical within a cylindrical casing such that the flame plume of the burning propellant is substantially perpendicular to the oxidizer flow. The solid propellant is preferably ignited substantially simultaneously with the ignition of the hybrid motor. The burning of the solid propellant prevents the flame from combustion of the fluid oxidizer and solid fuel in the hybrid motor from drifting and thereby stabilizes the flame front.
    • 在混合火箭发动机的燃烧室的前端设有火焰保持器。 火焰保持器包括限定空腔的高温壳体和在喷射器内或附近的腔内的固体推进剂。 推进剂可以设置在壳体内的环形空间中,使得来自燃烧推进剂的火焰羽流基本上平行于氧化剂的流动,或者可以在圆柱形壳体内通常为圆柱形,使得燃烧的推进剂的火焰羽流为 基本上垂直于氧化剂流。 固体推进剂优选与混合动力马达的点火基本上同时点燃。 固体推进剂的燃烧防止混合动力马达中的流体氧化剂和固体燃料的火焰流入,从而稳定火焰前沿。

    • A propellant is disclosed, comprising, as binder, an ethylene copolymer especially ethylene/vinyl acetate copolymer. The binder may be silane-grafted and moisture curable. A solid propellant composition may contain a plasticizer that is solid or semi-solid at 20° C., and an additive to increase one or more of elongation, adhesion and tack. Examples of the solid or semi-solid plasticizer are selected from microcrystalline wax, macrocrystalline wax, an oxidized hydrocarbon polyolefin and a polyketone wax. Examples of the additive are selected from an aliphatic hydrocarbon, an aromatic, a hydrogenated hydrocarbon resin and a derivative of a rosin. Preferably, the binder composition contains 10-30% by weight of liquid plasticizer, 0-30% by weight of solid or semi-solid plasticizer and 20-40% by weight of at least one said additive. The propellant is particularly useful as a rocket propellant. A method of manufacture is disclosed.
