Rounded Wings
Rounded wings are designed to give maximum stability in flight and smooth stabile responses from flight control surfaces. The rounded trailing edge gives the air more time to smooth out after the leading edge has disrupted its uniform state. Wing configuration still consists of flaps, ailerons, and the main wing. Larger, more stable planes were a necessity as military and civil demands increased for goods to reach destinations in a timely manner, no matter what the weather conditions.
