Abstract
Flight experiments on NASA Langley Research Center’ s B737-100 airplane were conducted to document e ow characteristics for further understanding of high-lift e ow physics. The measurements included surface pressure distributions measured using e ush pressure taps and pressure belts on the slats, main element, and e ap elements, and boundary-layer state changes measured using hot-e lm anemometry and infrared thermography. In this paper, results obtained in the e nal phase of e ight experiments are presented and analyzed. The analysis primarily focuses on changes in the boundary-layer state measured on the slat as a result of changes in e ap setting and/or e ight condition. The measurements show that extended runs of laminar e ow exist on the slat at relevant angles of attack. Flow mechanisms that affect the extent of laminar e ow include attachment-line contamination, crosse ow instability, and relaminarization.
