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.

A Bristol Bulldog Biplane Fighter is Once Again in the Sky

Vintage Aviation News

It actually flew fine, and it flies like a normal airplane. “If you view the video of the first flight on YouTube ( LINK ), you’ll see the airplane does some wiggling around, but most of that was done on purpose as I was trying to get the feel of it as fast as I could.” It is a terrible airplane for crosswinds.

Nemesis NXT

Plane and Pilot

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. From 1991-98, the original Nemesis became the winningest airplane in air race history, capturing 45 of 48 events. Just enough tail to do the job.

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. As seen from the aircrafts tail, the vortex rotates in the anti-clockwise direction on the right wingtip and the clockwise direction on the left wingtip. How Are Wingtip Vortices Formed?

Is Flying a Helicopter Harder Than Flying a Plane? A Comparative Analysis

Pilot's Life Blog

Aerodynamic Differences Fixed-Wing Aircraft (Airplanes) Airplanes , or fixed-wing aircraft, generate lift through their stationary wings as they move forward. The wings are designed with an airfoil shape, curved on the top and flatter on the bottom, creating a pressure difference when air flows over them.

The Hazards of Aircraft Icing: Explained

Pilot Institute

Ice can affect everything from how the airplane flies to the engines staying functional. Remember that wings, propeller blades, and tail surfaces are airfoil-shaped. Ice build-up on the airframe changes the airflow pattern around these airfoils. Many aircraft have heated leading edges on the wings, tail, and propellers.

The Role of Newton’s Third Law in Aviation

Pilot Institute

Application of Newton’s Third Law in Aviation When we talk about airplanes, we focus primarily on two forces: Lift (how the aircraft stays aloft). They are designed with a special shape called an airfoil, which encourages passing air to turn and deflect downward. This has only been possible by understanding the laws of physics.
