The invention relates to a combustion chamber casing, an engine and a helicopter, the combustion chamber casing comprises a casing inner shell and a casing outer shell which are connected with each other, a mounting cavity is formed in the casing inner shell, a first cavity is formed between the casing inner shell and the casing outer shell, and a plurality of nozzle seats are mounted in the first cavity; one end of the nozzle seat is communicated with the oil inlet pipeline, the other end of the nozzle seat is connected with a nozzle, and the nozzle is located in the mounting cavity. The combustion chamber casing is integrally sealed, so that parts except the connecting piece and the external fuel oil pipeline are located in the heat insulation cavity formed by the casing outer shell and the casing inner shell and are well protected by the inner shell and the outer shell, and external particulate matter and corrosive matter are prevented from invading; and the fuel oil pipeline and the nozzle seat are prevented from being impacted by external sand dust and corroded by corrosive substances.

    本申请涉及一种燃烧室机匣、发动机和直升机,其中,燃烧室机匣包括相互连接的机匣内壳体和机匣外壳体,所述机匣内壳体内形成安装腔,所述机匣内壳体与机匣外壳体之间形成第一腔体,所述第一腔体内安装有多个喷嘴座,所述喷嘴座的一端与进油管道相连通,所述喷嘴座的另一端连接有喷嘴,所述喷嘴位于所述安装腔内。本申请的燃烧室机匣整体密封,使得除连接件和外部燃油管路外的零部件处于机匣外壳体和机匣内壳体形成的隔热腔中,受到内外壳体的良好保护,有利于阻止外部颗粒物和腐蚀性物质侵入,防止燃油管路和喷嘴座受外部砂尘撞击和腐蚀性物质的腐蚀。
