Nemesis NXT

Plane and Pilot

In the late 1940s, surplus unlimited class World War II fighters, and for a while military jets, soon pushed 400 mph air race speeds out of reach. 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.

Learning Aeronautical Engineering From Historic Aircraft Designs

Vintage Aviation News

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. As shown by the Messerschmitt Me 262, the first operational jet fighter in the world, jet propulsion was the most innovative breakthrough of this age. ”

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. 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.

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

Vintage Aviation News

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. Its test flights provided data that shaped the designs of later swept-wing military aircraft, including the Century Series of jet fighters.

Today in Aviation History: First Flight of the Stipa-Caproni

Vintage Aviation News

Now, this might sound familiar, as this very idea that was born in Italy was an inspiration for modern-day jet propulsion. During these years, he concluded that the inner surface of the venturi tube needed an airfoil shape to achieve the greatest efficiency. The Stipa-Caproni in flight.

Flight Test Files: Grumman F-14 Tomcat

Vintage Aviation News

One of the standout aircraft in Drydens research history is the Grumman F-14 Tomcat, a legendary Navy fighter jet that played a key role in two major research programs at the center. These glove modifications served to smooth the wing surface and alter the airfoil to achieve specific pressure distributions.

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. A small Challenger 604 business jet flying at Flight Level 340 passed one thousand feet below an Airbus A380 flying the same route in the opposite direction. How Are Wingtip Vortices Formed?
