Classic Aero-TV: NASA Prandtl-D Project--Preliminary Research Design Lowers Drag

From 2016 (YouTube Version): CAUTION--Everything You Thought You Knew About Aerodynamics Is About To Be Tested...

When ANN CEO and Editor-In-Chief, Jim Campbell, attended the AMA Expo 2016, he probably never expected to get a lesson on advanced aerodynamics at a show that featured recreational radio controlled airplanes. However, he learned some amazing things about new aerodynamic research and is sharing it with you in this video.

Jim visited with, Albion Bowers, who is the Chief Scientist at NASA Armstrong. Among other things, Bowers is working on a program titled, ‘Preliminary Research Aerodynamic Design to Lower Drag.’  It’s called the PRANDTL project and is named after a researcher who started a search for aerodynamic solutions in the 1920s and 30s.

The project has set its sights on determining the minimum induced drag for a wing, and a key part of the research is being performed by radio controlled model aircraft.

During the video you’ll hear a fascinating discussion of advanced aerodynamics while watching video clips of NASA flying their research model aircraft. This video is much more than the story of the model aircraft; it’s a fascinating review of advanced aerodynamics. Try this for example, “Yaw becomes propulsive and you don’t need rudder pedals.” It’s also pointed out that birds don’t have a spin problem, and the same principle can be applied to airplanes.

Anyone who is interested in the research of advanced aerodynamics must watch this video.

Aero-TV is a production of the Internationally syndicated Aero-News Network. Seen worldwide by hundreds of thousands of aviators and aviation adherents, Aero-TV has produced over 2000 aviation and feature programs, including several hundred episodes of our daily aviation news program, AIRBORNE, hosted by Bri Cross. Parent company, Aero-News Network, has the most aggressive and intensive editorial profile of any aviation news organization and has published nearly 200,000 news and feature stories since its inception -- having pioneered the online 24/7 aviation new-media model that so many have emulated.
