A sailboat moving in the direction shown is tacking to windward against a north wind. The log registers a hull speed of 5.5 knots. A “telltale" (light string tied to the rigging) indicates that the direction of the apparent wind is 30° from the centerline of the boat. What is the true wind velocity vw? 5.5 knots 410 30°

4. The Wright brothers used a very thin wing on their 1903 flyer. In addition, they made extensive use of a homebuilt wind tunnel to test their wing designs. span, b chord, c Model of Wright Flyer (a) The Wright's wind-tunnel models had chord length, c, of about 0.04 m and wing span (length) of 0.26 m. The wind tunnel operated at approximately the same wind speed as the full-scale aircraft - about 13 m/s. Estimate the drag (friction) of a single wind-tunnel model wing under standard conditions (o = 1.225 kg/m³, = 1.7894 x 10-³ kg/s-m). Note that the wing is mounted in the wind tunnel so that both upper and lower surfaces are exposed to the flow. (b) The full-scale 1903 flyer had a chord length of 1.9 m and a wing span of 12.3 m. Estimate the drag (friction) of a single full-scale Wright flyer wing flying at 13 m/s under standard atmospheric conditions. (c) Consider the main wing configuration, which consisted of two wing surfaces (biplane) connected by 18¹ cylindrical rods. We will…
