Find the velocity required for maximum range. Consider a sailplane has wing loading of 110N/m^2 and K/CD0 of 0.35.(a) 10.3m/s(b) 10.3mph(c) 12.5mph(d) 9.2mphI have been asked this question during a job interview.My question comes from Flight Mechanics in section Performance and Flight Mechanics of Aircraft Design

Answer»

Correct option is (a) 10.3m/s

Easy EXPLANATION: VELOCITY = \(\sqrt{\FRAC{2*wing \,LOADING*\sqrt{K/CD0}}{density}}\)

= \(\sqrt{\frac{2*110*\sqrt{0.35}}{1.225}}\)

= \(\sqrt{106.24}\) = 10.3 m/s.
