A preliminary investigation has been made at low speed of the downwash behind various small-scale sweptback wings. The wing configurations for which data were obtained covered aspect ratios from 2.5 to 4.0, sweepback angles from 32.5 degrees to 40 degrees, and ratios of root chord to tip chord from 0.62 to 2.06.
