Tailless Aircraft: How Airplanes Fly Without a Tail

Pilot Institute

Have you ever seen an airplane with no tail and no vertical fin, but with just a sleek wing? A tailless aircraft is a fixed-wing airplane without a horizontal stabilizing surface. A tailless airplane is one where everything needed to fly, like lift, control, and stability, is built into the main wing.

Mastering Stalls: How to Recognize, Prevent, and Recover Safely

Flight Training Central

Depending on design, airfoils used in general aviation, stall at angles of attack between 16 to 18 degrees. A wing will always stall at the same angle of attack; however, weight, and bank angle, power setting and load factor may change the speed or the pitch attitude at which the airplane stalls.

Wingtip Vortices and Wake Turbulence

Pilot Institute

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. If youre flying an airplane with a short wingspan, you should do everything you can to avoid severe wake turbulence. How Are Wingtip Vortices Formed? Mass and inertia also matter.

What Is Bernoulli’s Principle? A Simple Guide for Pilots

Pilot Institute

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.

Learning Aeronautical Engineering From Historic Aircraft Designs

Vintage Aviation News

Early airplane lessons for engineers on low-speed aerodynamics and stability control By using wind tunnel testing to improve their wing designs, the Wright brothers established a standard for contemporary aeronautical research and demonstrated that even basic tests may provide revolutionary findings.

Chord Line in Aviation? What It Is and Why It Is Important

Pilot Institute

Airplane wings vary in shape and size, but all have standard features like the chord line. In general, the chord line is used as an easy-to-understand reference when referring to the properties of a wing or airfoil. Basically, the mean camber line is meant to indicate the midpoint between the top and bottom surfaces of the airfoil.

Flight Test Files: Convair XF-92A Dart

Vintage Aviation News

The delta wing’s large area (425 square feet), thin airfoil cross section, low weight, and structural strength made a great combination for a supersonic aircraft. Photo NACA/NASA The single-place XF-92A airplane had a delta wing swept at 60 degrees. It was built as a test bed for a proposed interceptor that never materialized.
