摘　　要：针对在压气机特性拟合计算中存在的部件特性不完整问题,提出一种基于经验方程的船用三轴燃气轮机压气机特性计算方法。通过经验方程的引入,求解出所缺少的高压压气机特性方程,继而建立了完整的压气机特性计算模型。分析表明该模型具有较高的精确度,能够满足船用三轴燃气轮机压气机变工况特性计算的需要。Based on the experience equations,a method to calculate the compressor performance is advanced to settle the question of the deficiency of component performance curves. Based on the experience equations, the performance equations of the high pressure compressor are found. Then the compressor model of the gas - turbine is established.The analysis proves the precision of this method, and the model is competent for the calculation of the compressor performance in different conditions.
