Standard wind tunnel models are usually (but not always) intended for one of the basic wind tunnel measurement types, such as the measurement of forces and moments with force balances or measurements of pressure distribution. Results of wind tunnel tests of these models are generally published in the form of nondimensional aerodynamic coefficients (thus being made independent of model size) and made available to the wind-tunnel community, often in review reports containing inter-facility comparisons of data, discussing observed scatter of results, different testing conditions, production differences between models etc.
