摘　　要：本文简介了前缘后掠角为７５°的平板三角翼在西北工业大学ＮＦ－３低速风洞中的测力和相关的激光片光流动显示实验，给出了部分实验结果，并与文献［１－３］的结果进行了比较，虽然各种来源的结果存在着明显的差异，但ＮＦ－３风洞两种测试手段的实验结果却具有良好的相关性。The stall characteristics of a 75° sweep slender delta wing are investigated in NPU NF 3 wind tunnel experiment by means of laser lightsheet flow visualization and force measurement tests. The results obtained by the two measuring methods are in good agreement, although great discrepancy with some known reference sources are found.
