AMA Expo West 2018 - NASA's Al Bowers: Prandtl Wing Update

Armstrong Chief Scientist Al Bowers challenged the fundamental core assumptions of leaders in the field of aviation: their solutions to overcome adverse yaw were wrong. With a nod to German aerodynamicist Ludwig Prandtl’s 1933 theory of minimum induced drag and bending moment, Bowers named the first iteration of his work the “Preliminary Research Aerodynamic Design To Lower Drag (PRANDTL-D)”. He began his multiple-year trek to prove that not only could adverse yaw be overcome, but it could be turned into proverse yaw for aircraft, without relying on rudders or complicated computerized flight controls to accomplish it - just as birds achieve it. https://www.nasa.gov/centers/armstron... https://www.amaflightschool.org/PRANDTL Like us on Facebook: https://bit.ly/AMA-FB Join our Facebook group: https://bit.ly/iFlyAMA Follow us on Instagram: https://bit.ly/AMA-Insta Read the latest digital edition of Model Aviation magazine: https://bit.ly/MA-Digital Visit the National Model Aviation Museum online: https://bit.ly/AMA-Museum Keep up to date with FAA and AMA Government Advocacy News: https://bit.ly/AMA-Gov Help support the preservation and advocacy of the hobby: https://bit.ly/AMA-Donate Learn more about the AMA: https://bit.ly/About-AMA Become a member https://bit.ly/Join-AMA #iflyama #AMAexpotop10 #NASA
