| The first single-seat fighter of indigenous US design to
achieve production status, the Model D was conceived
around the 300hp Hispano-Suiza H eight-cylinder
water-cooled engine. The first of four prototypes built
by the Ordnance Engineering Corporation (Orenco)
was completed in January 1919. Curtiss was assigned a
production contract for 50 aircraft and undertook some
redesign. This included the introduction of dihedral
and overhanging, balanced ailerons, and revision of the
engine installation. Of wooden construction with plycovered
fuselage and fabric-covered wings, the Curtiss-
built Model D utilised a 330hp Wright-built derivative
of the French engine and carried an armament of
two 7.62mm machine guns, deliveries commencing
in August 1921. One Model D was experimentally
fitted with French Lamblin radiators attached
to the fuselage sides, and another was fitted with a
turbo-supercharger for high altitude trials.

| Lou, e-mail, 10.07.2012 00:35 I read a french article on this plane that stated that curtiss used the mock-up wing that orenco had supplied to them as a template. The wing eventually failed in more than one aircraft and all the ORENCO D's were grounded and taken out of service. reply |
