The '''Nuri Demirağ Nu.D.38''' was a Turkish light civil transport, with twin engines and seating for four passengers, built in the early 1940s.<ref name=JAWA41/>  Only one was constructed and flown.
==Design and development==
Design work on the Nu.D.38 twin engine light transport began about 1936<ref name=TkTL/> and the aircraft was largely completed by 1941,<ref name=JAWA41/> but the first flight was delayed until 1944.<ref name=Rusjet/> Turkey remained neutral through most of World War II, only entering the war in 1945, after the first flight.<ref>{{cite book|last=Hasanli|first=Jamil|title=Stalin and the Turkish Crisis of the Cold War, 1945-1953|url=https://books.google.com/books?id=QS_8hTWEG0AC&pg=PA42|access-date=2011-10-10|year=2011|publisher=Lexington Books|location=Lanham, MD|isbn=978-0-7391-6807-3|pages=42–43}}</ref>
The Nu.D.38, manufactured by [[Nuri Demirağ]] in [[Istanbul]], was a [[wing configuration|high]] [[cantilever|cantilever wing]] aircraft.  The wing, of tapered plan and all aluminium alloy stressed skin construction had a built up main spar and a secondary spar.  There were pairs of split [[flap (aircraft)|flaps]] inboard of the fabric covered [[ailerons]]. The fixed surfaces of the tail unit were also aluminium alloy structures with stressed metal skin. The tailplane, set at the top of the [[fuselage]], was strut-braced from below.  Control surfaces were fabric covered, with [[trim tabs]].<ref name=JAWA42/>
The fuselage of the Nu.D.38 was an oval cross-section aluminium alloy [[monocoque]], with stressed skin over frames and longitudinal [[Longeron|stringers]].  The crew sat side by side at dual controls in a cabin with side access doors.  The passenger compartment seated four, each with their own window, and was accessed through a starboard side door.  There was a compartment for luggage or mail in the nose.<ref name=JAWA42/>
The Nu.D.38 was powered by two 160&nbsp;hp (120&nbsp;kW) [[Siemens-Halske Sh 14|Bramo Sh 14-A4]] radial engines, mounted to the main wing spar on steel frames.  It had a fixed, [[conventional undercarriage]].  A main shock absorber leg was attached to each of the steel engine frames, braced rearwards by a short auxiliary strut.  Legs and wheels were enclosed in [[aircraft fairing|fairings]].<ref name=JAWA42/>
==Operational history==
The Nu.D.38 was first flown on 11 February 1944.  No further aircraft were produced.<ref name=Rusjet/>
