Tip aerodynamics from wind tunnel test of semi-span wing

Presented are the results of a low-speed wind tunnel test on a 5.33-aspect-ratio, semi-span wing with 30- and 35 deg swept tapered tips. The test results include aerodynamic data for the tip itself and for the entire wing including the tip. The metric tip extended inboard 1.58 wing chord lengths. The aerodynamic drag data show the strong influence of tip incidence angle on tip drag for various lift levels. Pitching-moment characteristics show the effect of a moment center at 0.13 c and 0.25 c.
