This setup makes the wing less efficient overall, but it can reduce drag, weight, and cost compared to using a separate tail. High aspect ratio wings reduce drag and improve performance during climb or slow flight. On the flipside, a decrease in aspect ratio will result in higher drag. This type of design is a reflex airfoil.

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!

When he created his principle of differential pressure, he had no thoughts about its future application to the development of airfoils and lift production. With some imagination this looks a bit like the top of an airfoil. In the case of our airfoil, we’ll assume that the fluid is air and that the air is relatively still.

From the first days of flying to the evolution of supersonic jets, historic aircraft offer a road map for comprehending the ideas guiding aeronautical engineering. Particularly in battle aerodynamics, drag reduction, and structural durability, early aircraft teach engineers today important insights.

Airfoils use this principle, with faster airflow over the top creating lower pressure. Bernoullis principle also applies to how carburetors and jet engine inlets work. Jet Engine Inlets Jet engine inlets also rely on Bernoullis principle, although they use it differently than carburetors.

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.

Why do jet pilots talk about speed in terms of Mach number? Jet aircraft often fly at speeds close to the speed of sound. Lift, drag, and handling correlate well with IAS in the lower atmosphere. Making the wing relatively flat on top with a blunter leading edge and more curvature on the bottom gives you a supercritical airfoil.
