采用准三维的计算方法，对一台两级航空燃气涡轮的低压导叶进行了改造设计，采用复合倾斜叶片以提高涡轮效率。对叶片倾斜和冷气掺混所引起的问题进行了处理和分析。
The quasi-three-dimensional calculation method is adopted to design the low-pressure guide vane of a two-stage aviation gas turbine. The composite inclined blade is used to improve the turbine efficiency. The problems caused by blade inclination and air-conditioning blending have been dealt with and analyzed.
