| Designed by the US Army Engineering Division as a
specialised single-seat night fighter, two prototypes of
the PN-1 were built by Curtiss, powered by the 220hp
Liberty L-825 six-cylinder water-cooled engine. Optimised
for docile handling characteristics at the lower
end of the speed range in order to ease operation from
small blacked-out fields, the PN-1 was completed without
interplane struts, but steel-tube N-type struts were
introduced to improve torsional stiffness before any
attempt to fly the first prototype. In the event, only this
one PN-1 was completed, and the results of any flight
testing are not on record. It is known, however, that the
sole prototype was used for static tests at McCook Field
during 1921.

| David Hewett, e-mail, 06.09.2008 20:18 Interesting to see that this was a US Army Engineering Div. design. I have blueprints of the Ordnance Engineering Dept. Single Seater Pursuit Type D.A., also identified on b.p. as Model D, 290 H.P. Liberty 8 Pursuit Fighter, which is a biplane with 242 sq.ft. total main planes, which I believe was designed but never built. Huge blueprints, one now separated at all folds, but all pieces present, designer unsigned, issued by Ordnance Engineering Corporation, Baldwin, Long Island, New York, which puts it circa 1918-9. From estate of Alec. Miller, Curtis flyer, builder. reply |
