The embodiment of the invention discloses a mixed flow fan used for a stratosphere, an aerostat and an aerostat control system, and relates to the field of aerostats, and compared with a common aviation fan, the mixed flow fan used for the stratosphere has the advantages that the pressure head, the flow and the response time are improved, and the height adjusting capacity of the aerostat is improved. The mixed flow fan for the stratosphere comprises a shell and an impeller, a cavity is formed in the shell, an air inlet and an air outlet which are communicated with the cavity are formed in the shell, and the air outlet is used for inflating a bag body of an aerostat; the impeller is arranged in the cavity and rotates around the axis direction of the impeller to drive airflow to flow through the impeller from the air inlet and then flow out of the air outlet, an air flow channel is formed between the impeller and the shell, and the direction of the air flow channel entering the air inlet side of the impeller is parallel to the axis direction of the impeller. And an acute included angle is formed between the gas flow channel direction flowing out of the gas outlet side of the impeller and the axis direction of the impeller. The mixed flow fan for the stratosphere is used for adjusting the height of the aerostat.
本申请实施例公开了一种用于平流层的混流风机、浮空器及浮空器控制系统,涉及浮空器领域,本申请提供的用于平流层的混流风机,相比于常用的航空风机,提高了压头、流量和响应时间,提升了浮空器的高度调节能力。该用于平流层的混流风机包括壳体和叶轮,其中,壳体内形成有空腔,壳体上设置有与空腔连通的进气口和出气口,出气口用于向浮空器的囊体充气;叶轮设置在空腔内绕叶轮的轴线方向转动,带动气流从进气口流经叶轮后从出气口流出,叶轮与壳体之间形成气体流道,进入叶轮进气侧的气体流道方向与叶轮的轴线方向平行,流出叶轮出气侧的气体流道方向与叶轮的轴线方向呈锐角夹角设置。该用于平流层的混流风机用于调节浮空器的高度。
