NASA's Armstrong Flight Research Center engineers in Edwards, California, are working on an increasingly complex aircraft called the Preliminary Research Aerodynamic Design to Lower Drag, or Prandtl-D.
NASA has provided a report and files that contain geometry in an effort to allow others to build and analyze this aircraft design!
Tom Sanders demonstrates how to modify a stock balsa glider, including adding a launch lug and setting the wing's dihedral. We are excited to be able to share this new project video with you. Additional instructional information is coming soon!
Originally featured in the March 2015 issue of Model Aviation magazine, Laddie Mikulasko details how to build the Curtiss CW-24B. This is a scale of one of the U.S. Army's one-of-a-kind fighter aircraft.
Sir George Cayley, often called the Father of Aeronautics, designed a helicopter powered by a bow-string mechanism with feather blades (similar to the reproduction shown here). Later, he experimented by flying a model with multiple adjustable surfaces, allowing him to understand how every change affected the model’s flight. This model is a ½ scale replica of his original 1804 model. Cayley used the data from these experiments to publish his On Aerial Navigation in 1809.
