Tailless Aircraft: How Airplanes Fly Without a Tail

Pilot Institute

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.

Wingtip Vortices and Wake Turbulence

Pilot Institute

The exhaust coming out of aircraft engines looks pretty dangerous, generating huge amounts of thrust and pushing back tons of hot air. 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. Increased Drag Moving air around is hard work!

Flight Test Files: The Douglas D-558-2 Skyrocket – Chasing Mach 2

Vintage Aviation News

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.

Air pressure and density

Professional Pilot

Every pilot knows that aircraft fly because the forces of lift and thrust balance or exceed the weight and drag countering them. Aeronautical engineers improve continually on that imbalance with better airfoils and powerplants along with aircraft designs and materials to reduce weight and drag.

Mach Number Explained: What It Is and Why Pilots Use It

Pilot Institute

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. This type of wing redirects the shockwaves further aft on the wing, reducing drag. on dry thrust alone.

The Role of Newton’s Third Law in Aviation

Pilot Institute

This principle is fundamental in generating lift, thrust, and maneuverability, allowing aircraft to fly. Thrust (how it moves forward). They are designed with a special shape called an airfoil, which encourages passing air to turn and deflect downward. That force is called thrust. Wings do just that.

What Is a Variable-Sweep Wing? How Swing Wings Work

Pilot Institute

As you reach high speeds, especially near or above the speed of sound, you can then sweep the wings back to reduce drag. They delay the formation of shock waves that cause wave drag. But when you’re doing high-speed dashes, sweeping the wings back will reduce drag. Lower required thrust, and shorter takeoff and landing rolls.
