he corrugations rolled on a grooved wood form. The dimensions of these corrugations (fig. 4) were found by scaling down the average of several standard wings. Since it is impractical to run the corrugations com- pletely around the leading edge, the sheet was left flat there, the corrugations… … Figure 2— Arrangement for tare drag test and the leading edge construction necessitated slight departures from the basic Clark Y section.
