摘要: 为了使气动热力模型更好的逼近涡轮发动机,应用成熟的非均匀B样条来拟合部件特性.这种方法既可以保证发动机计算的整体性能也大大提高了其局部特性的准确性.单轴涡喷发动机的算例证明了方法的有效性.Abstract: Non-uniform rational B-splines(NURBS) was used to fit component characteristics of aerothermodynamic model for approaching turbine engine.This method ensures that the overall and local characteristics of the model can be improved greatly with NURBS.The validation of method is demonstrated by one-spool turbojet engine.
