説明
<p>To improve the aerodynamic performance at take-off and landing flight and coexist with the natural laminar flow wing geometry, the capability of the Krueger flap and its flow mechanism were investigated on a JAXA-QSST configuration. Parametric studies using numerical analysis are conducted on variation of the mutual locations between Krueger flap and main wing, and the flap deflection angles. The lift-to-drag ratio characteristics are strongly influenced by the mutual locations and deflection angles by effectively controlling the vortex flow over the flaps and main wing. Comparing with the conventional leading-edge flaps, higher lift-to-drag ratio is obtained by the Krueger flap. Because, the vortex lift at the flap and suppression of flow separation at main wing improve the lift-to-drag ratio by the Krueger flap deploying. </p>
