Flying Wing alternate model made exclusively from parts found in Lego set 6745.
About this creation
For many years prior to the development of the XB-35 bomber, the Northrup aircraft company engaged itself in the design and testing of the flying wing concept. Jack Northrup felt that an airplane that had no discernable fuselage and as few other protuberances as possible would offer the lowest drag and therefore the highest efficiencies for an aircraft's design. There were many concepts that were made that led up to the production of the XB-35, including the inspiration for this LEGOŽ model, the Northrup N-9M.
The N-9M was a 1/3 scale proof-of-concept airplane that was used to help work out some of the design, manufacturing, and unusual flight controls that would be necessary in the larger XB-35.
The N-9M had two pusher propellers.
There were at least four N-9M's produced.
There is one N-9M that has been fully restored to flying condition and still makes appearances at air shows.
The main challenge in building this model was creating a large swept wing, and still allowing for the cockpit and engines to have a non-orthogonal relationship to the wing while maintaining the connections necessary to have a strong model. The model itself is strong and swooshable!
