Northrop N-1M

In 1929 John Northrop designed and developed a two-seat single-engine aircraft which was basically a flying wing with two slim booms supporting the tail unit. The aircraft, built by Northrop's newly formed Avion Corporation (later the Northrop Aircraft Corporation) was powered by a 67kW Menasco engine, initially driving a pusher propeller but modified later to tractor configuration.

Experience with this early aircraft was stored away for a decade until Northrop could pursue his all-wing concept, but in 1940 the Northrop N-1M flew with two 48kW Lycoming engines buried in a thick wing to drive pusher propellers. The N-1M was a true all-wing design and its low drag gave improved acceleration in both dive and glide; it also enabled the aircraft to use significantly less power on take-off than conventional aircraft of similar size and weight. Early tests found few problems, the main one being engine cooling, but this was solved by the installation of 89kW Franklin engines with three-bladed propellers and improved baffles. The N-1M has survived in the US National Air and Space Museum.

it would be a great glider

.when i was a kid it flew over elsegundo many times,color was yellow,took off from mines field [LAX]or hawthorn.saw a copy flying at gillespiefield el cajon S.D. confederate airforce air show what a sight in low level 90 turns,a few years back.so the n-1m is still flying what a sight.

I HEARD SOMEWHERE YOU COULD MAKE A 1:1 SCALE FLYING KIT OF A FLYING-WING. BUT FOR A N-1M AND N-9M IS IMPOSSIBLE. SORRY.

Jacob S. Hazlett, jacob.hazlett=us.army.mil, 26.12.2007

Dear Sir, I would like to find a full set of blue prints to make a homebuilt N-1M and also a N-9M? I was a journeyman aircraft structural mechanic for the U.S.Air Force, I am also heavy into R.C. model planes. Could you point me in the right direction? Thank-you Sir, Respectfully Jacob S. Hazlett

Do you have any comments about this aircraft ?
