The invention discloses an aero-engine non-rotating double-layer structure anti-icing rectification cap cover which comprises a rectification cover shell and a rectification cover screen, the middle of the whole rectification cover shell and the middle of the rectification cover screen are welded and fixed, and an inner cavity is formed between the rectification cover shell and a rectification cover for anti-icing gas to flow; the front end of the fairing shell is welded and fixed with the upper edge of the outer end of the fairing bushing, and an anti-icing airflow discharge outlet is formed between the front end of the fairing shell and the fairing bushing; and the lower edge of the inner end of the fairing bushing is welded and fixed with the front end of the fairing screen, so that an inner cavity formed by the fairing shell and the fairing screen is communicated with the anti-icing airflow discharge outlet. The rectification cover hood is connected with the fan casing into a whole through a center bolt, anti-icing airflow enters the front edge of the rectification cover hood along an inner cavity formed by the rectification cover shell and the rectification cover screen, heats the outer surface of the shell and finally enters a main flow channel through a discharge outlet formed by the rectification cover lining and the rectification cover shell at the front edge of the rectification cover hood. The technical problem of anti-icing of the non-rotating rectification cover hood is solved.

    本发明公开了一种航空发动机非旋转的双层结构防冰整流帽罩,包括:整流罩壳体、整流罩屏,整整流罩壳体和整流罩屏中部焊接固定,并在整流罩壳体和整流罩之间形成内腔供防冰气体流动;整流罩壳体前端与整流罩衬套外端上边焊接固定,并在整流罩壳体前端与整流罩衬套之间形成防冰气流排放出口;整流罩衬套内端下边与整流罩屏前端焊接固定,使得整流罩壳体与整流罩屏组成的内腔与防冰气流排放出口连通。整流帽罩通过1个中心螺栓与风扇机匣连为一体,防冰气流沿整流罩壳体和整流罩屏构成的内腔进入整流帽罩的前缘,并加热壳体外表,最后通过整流帽罩前缘处由整流罩衬套与整流罩壳体形成的排放出口进入主流道。解决了非旋转整流帽罩防冰技术问题。
