Spin Tests of Two Models of a Low-Wing Monoplane to Investigate Scale Effect in the Model Test Range (open access)

Spin Tests of Two Models of a Low-Wing Monoplane to Investigate Scale Effect in the Model Test Range

Note presenting testing performed on scale models of a modern low-wing monoplane in the 15-foot free-spinning wind tunnel. Results are presented in the form of charts that afford a direct comparison between the spins of the two models for a number of different conditions. The results indicate that, within the range of Reynolds numbers used in the present investigation, such factors as difficulty of ballasting and testing are more important in determining proper model size than the changes in scale effect likely to result from the use of different sizes of models.
