Q: The ultralight plane Gossamer Condor in 1977 was the first to complete the Kremer Prize figure-eight course solely under human power. Its wingspan was 29 m, with Cav = 2.3 m and a total mass of 95 kg. Its drag coefficient was approximately 0.05. The pilot was able to deliver 1/4 horsepower to propel the plane. Assuming two-dimensional flow at sea level, estimate
(a) The cruise speed attained,
(b) The lift coefficient; and
(c) The horsepower required to achieve a speed of 15 knots.
