Question: 1.4 Estimate the skin-friction coefficient for a flat plate wing of 4 m chord and 10 m span exposed to an airstream of 75 m/s. Assume that the boundary-layer transition occurs at 50% chord and v=1.5 x 10- m²/s.
WebNov 3, 2024 · 4. The Concorde, like many other supersonic aircrafts, had very thin airfoil mainly due to aerodynamic reasons. This answer gives a good overview on this topic. Anyway the airfoil was definitely not flat i.e. … In 1974, a NASA-funded study prompted by Kline and Fogelman's claims and the resulting national coverage found the airfoil to have worse lift-to-drag ratio than a flat plate airfoil in wind tunnel tests. In the 1990s, after the original patents expired, researchers returned to the topic of stepped wings. A 1998 study by Fathi Finaish and Stephen Witherspoon at …
