| Abstract: | The problem of scale effect arising in spin model freeflight tests is discussed.This can be of significance for setting up thecorrelation between model free flight tests and aircraft flight tests.The analysis of the influence of scale effect on model free flight stall/spin tests is given, and an engineering prediction method including thescale effect in model free flight stall/spin tests is proposed. |
