ARDA Mk 8 - The Northrop N9M-b

Advanced Reduced Drag Aircraft
By Jean-Louis Naudin
created on August 23h, 2001 - JLN Labs - Last update March 3, 2002

The ARDA flying wing Mk 8, a 1/10 scale of the Northrop N9M-b, is a mockup used for validating the flight model in real conditions. On August 25th, 2001, the ARDA wing has been tested successfully propelled with two electric engines.

" The 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.

Notes from JL Naudin : I really enjoy to pilot the N9M-b flying wing. The flight of a flying wing is always magic for the eyes !!!...
I am grateful to Laurent Buissyne for his wonderful design ( RCM-224 )
