Tests in the Ames 40- by 80-foot Wind Tunnel of Two Airplane Models Having Aspect Ratio 2 Trapezoidal Wings of Taper Ratios 0.33 and 0.20

Memorandum presenting tests of two airplane models with trapezoidal wings of aspect ratio 2 and taper ratios of 0.33 and 0.20. For each model, a fuselage with a fineness ratio of 12.5, a thin, triangular, vertical tail with a constant-chord rudder, and a thin, unswept, all-movable horizontal tail was used. Tests of the wing-fuselage vertical-tail configuration and of the complete airplane model were made for both models.
