FLIGHT TEST RESULTS FOR AN ADVANCED TECHNOLOGY LIGHT AIRPLANE WING

Flight test results are reported for a Cessna Cardinal single engine light airplane modified by the installation of advanced technology wings incorporating reduced area, Fowler and Kruger flaps, and spoilers for roll and flight path control. Comparisons with the unmodified airplane show increased cruise speeds, smoother ride in turbulence, and major increases in maximum lift coefficient. Excellent roll control is achieved with spoilers. Several design features incorporated in the new wings show considerable promise for incorporation in future light airplanes.
