The invention provides an ejector, an auxiliary power device for an airplane and the airplane. The ejector comprises a main spraying unit, a deflation unit, a cooling unit, an ejection unit and a mixing section. Wherein the main spraying unit, the injection unit and the mixing section are sequentially connected, the cooling unit is connected with the injection unit, the deflation unit is connected with the injection unit, and the mixing section is located at the most downstream position of a fluid channel; furthermore, main airflow from the main spraying unit, cooling airflow from the cooling unit and deflation airflow from the deflation unit are mixed together and discharged through a mixing section. According to the ejector, the energy of deflation gas can be well utilized, meanwhile, the uniformity of a flow field in the ejector is remarkably improved, and therefore the ejection capacity of the ejector is improved, and the strength service life of the ejector is prolonged.

    本发明提供了一种引射器、飞机用辅助动力装置及飞机,引射器包括主喷单元、放气单元、冷却单元、引射单元和混合段;其中,所述主喷单元、所述引射单元和混合段依次连接,所述冷却单元与所述引射单元相连接,所述放气单元与所述引射单元相连接,所述混合段位于流体通路的最下游处;进一步地,来自所述主喷单元的主气流、来自所述冷却单元的冷却气流和来自所述放气单元的放气气流混合在一起通过混合段排出。本发明能够很好的利用放气气体能量,同时显著提升引射器内部的流场均匀性,进而提高引射器的引射能力和强度寿命。
