Part I: Frise ailerons on a Harvard II aircraft Author Templin, R.J. Etkin, B. Institution National Research Council Canada Date 1948-12-31 Abstract An attempt has been made to correlate the lift and hinge moments measured in flight on a Harvard II aircraft with those obtained in wind tunnel tests of a 0.40 scale model of the outer wing panel. For the purpose of comparison, both model and full scale results were reduced to the common case of an aircraft with an infinitely rigid wing, no tail, and no slipstream. The most important single factor in correlating the results was found to be the corrections for restraint of the wind tunnel walls, the model being large relative to the tunnel dimensions. The agreement is considered sufficiently good that the model test results when properly interpreted may be used for design purposes.
