The advanced small gasturbines feature small mass flow ratio, short vanes and blades with low aspect, high second flow and blade tip leakage losses, and low efficiency.
先进的小发动机涡轮的流量小，叶片短，展弦比低，二次损失及叶尖漏泄损失大，效率低，温度高冷效差。
Due to the thrust reverser guide vane not considered in the model, the parameter (ie. thrust reverser mass flow ratio) that is proportional to reverser thrust was used to evaluate the performance.
在计算模型中没有考虑反推导叶，为此，用与反推力成正比的参数，即反推质量流量比来衡量性能的优劣。
The influence of blade number, blade thickness, location of splitter blades and tip clearance on mass flow, pressure ratio and efficiency is showed.
讨论了改变叶片数目，增加叶片厚度，调整分流叶片周向位置以及增加间隙高度等对离心叶轮流量、压比和效率等总体性能的影响。
