Aerial Banner Drag An aircraft is towing an aerial banner as illustrated in the figures below. 5m Configuration A 10m Configuration B 10m 5m In the following parts, assume that the flow over the banner remains laminar, so that the Blasius solution is valid. 1 a) Compute the drag force on the banner in configuration A at an airspeed of 60mph at sea-level conditions. Comment on whether you think your answer is realistic. b) Repeat the drag calculation in the previous part for configuration B. Comment on the differ- ence in drag compared to configuration A. c) Repeat the drag calculation on configurations A and B using an airspeed of 120 mph. How does the drag scale with airspeed?
