1·This paper represents a CFD method for the design of NLF airfoils directly under transonic viscous flow conditions.

本文介绍一种设计跨声速自然层流翼型的计算流体力学（CFD）方法。

2·The design results show that the amount of the NLF satisfies the target requirements, and that the design approach used in the study is applicable to a wide rang of airfoils.

计算结果表明，设计结果的层流范围和设计目标基本吻合，该方法可以用于NLF翼型的多目标反设计中。

3·Simulation results show that the NLF algorithm has advantages of both less computations and better tracking performance, therefore, it can be widely used in radar engineering.

仿真结果表明，NLF算法具有计算量小、跟踪性能好等特点，有较好的工程应用价值。
