This is a sliced version from the original Prandtl-d-3 from the AMA website: https://www.amaflightschool.org/PRANDTLThis model is sliced so it can be printed easier. I used a 5-10 % infill and 1-2 outer layers. Printed in ABS for testing. see video for more info. This version is 550mm tip to tip in 4 parts. more info: https://ntrs.nasa.gov/citations/20160003578https://www.nasa.gov/centers/armstrong/news/newsreleases/15-24.htmlhttps://www.nasa.gov/centers/armstrong/news/FactSheets/FS-106-AFRC.htmlOriginal model here: https://www.amaflightschool.org/PRANDTLif you want the model i cut up... let me know. ill upload it some where... https://ntrs.nasa.gov/api/citations/20160003578/downloads/20160003578.pdfhttp://airfoiltools.com/airfoil/details?airfoil=prandtl-d-root-nshttp://airfoiltools.com/airfoil/details?airfoil=prandtl-d-tip-nsmore links:https://forum.flitetest.com/index.php?threads/nasas-prandtl-d-flying-wing-no-vertical-surfaces-with-no-control-problems.26122/Thanks!
