NACA-RM-L58B05
Low-subsonic investigation to determine the chordwise pressure distribution and effectiveness of spoilers on a thin, low-aspect-ratio, unswept, untapered, semispan wing and on the wing with leading and trailing-edge flaps
Year: 1958
Abstract: INTRODUCTION
Considerable interest has been shown in the use of spoilers for lateral control and gust alleviation. The spoiler is more effective as a lateral control when it is located in a more rearward position, and, as pointed out in references 1 and 2, the spoiler is more effective as a gust alleviator (reduces the lift-curve slope) when it is located in a more forward position.
The present investigation was made in the Langley 300-MPH 7- by 10-foot tunnel to obtain the static longitudinal and lateral aerodynamic characteristics and the chordwise pressure distribution at the 60-percentsemispan station over a thin, low-aspect-ratio, unswept, untapered, semispan wing with a 10-percent-chord projection spoiler of various spans located at various chordwise locations on the wing with leading- and trailing-edge flaps.
The results of the investigation are presented without discussion. Pressure coefficients, section normal-force coefficients, and section pitching-moment coefficients are presented in tabular form.
