Particularly in battle aerodynamics, drag reduction, and structural durability, early aircraft teach engineers today important insights. Setting the benchmark for modern airliners, the Douglas DC-3 (1935) a classic in commercial aviation brought all-metal construction, retractable landing gear, and more efficient airfoil designs.

They flew a total of 313 missions, collecting invaluable data on pitch stability, lift, drag, and buffeting in transonic and supersonic flight. The jet- and rocket-powered aircraft exceeded expectations, performing better than predicted in high-speed wind tunnel testsparticularly in drag performance above Mach 0.85.

When air flows over the aircraft wing, the shape of the airfoil creates low pressure above the wing and relatively higher pressure below the wing. This horizontal component of lift is called Induced Drag. Its called induced drag since it only exists as a consequence of lift. Increased Drag Moving air around is hard work!

Davis, who had developed a new wing, whose airfoil had a lower drag co-efficiency than other wing designs of the time, and which had already been used on the company’s Model 31/XP4Y Corregidor flying boat. The company had hired a freelance aeronautical engineer, David R.

The term 'angle of attack' is defined as the angle between the airplane's longitudinal axis and that of the air striking the airfoil. Air traveling faster over the curved upper surface of an airfoil causes lower pressure on the top surface. The four forces acting on an airplane in flight are lift, weight, thrust, and drag.

Airfoils use this principle, with faster airflow over the top creating lower pressure. If lift were entirely due to Bernoulli, a symmetric airfoil (one with equal curvature on top and bottom) wouldnt generate lift – yet it does when given the right angle of attack. In reality, the wing also uses Newtons third law to create lift.

The NXT was designed using computer-based computational fluid dynamics (CFD), NASA-derived airfoils, and was tested in the Lockheed wind tunnel to refine the aerodynamics. However, like any overnight success story, the actual journey to the NXT began in the early 1990s with the original Nemesis.
