The advanced small gasturbines feature small massflowratio, 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 massflowratio) 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 massflow, pressure ratio and efficiency is showed.
