UAV-ARDA mk 9 "XB-35"
Advanced Reduced Drag Aircraft
By Jean-Louis Naudin
created on April 28, 2002 - JLN Labs - Last update June 9, 2002
flying wing airplane is the most evocative shape in
aviation : a pure wing, unencumbered by tail surfaces or
a fuselage, producing lift over every square meter of its
surface. ". Richard P. Hallion (PhD), the US
Air Force historian.
" L'aile volante représente la configuration aéronautique la plus aboutie : une aile dont la pureté n'est pas altérée par des empennages ou un fuselage, et dont chaque mètre carré de sa surface génère de la portance ". Richard P. Hallion (PhD), directeur du service historique de l'US Air Force.
Note from JL Naudin : This model is the 1/14 scale model of the Northrop XB-35 Flying Wing build by Jack Northrop in 1946. It is full powered by electric energy and able to fly up to 10 minutes.
