The development of half-model test techniques in NF-3 wind tunnel are introduced. Some test results of force measurement and flow visualization are presented to investigate the influence the half-model spacer and the joint structure of high-lift system. Based on the results, proposals on half-model spacer height selection and model design are put forward.
