Ufag C.I History

The Ufag C.I was a two-seat, single-engine biplane fighter serving the Austro-Hungarian Empire air services. The aircraft made its first appearance in April of 1918 and proved an excellent mount that it quickly warranted a quantitative production order for 284 examples to go along with the original eleven. Despite the large order, only 166 of these aircraft were delivered by October of 1918, with the war officially over by November. The C.I was initially fielded with the Fliks 47/F and Fliks 58/D. The Ufag C.I emerged from the Hansa-Brandenburg C.II design, essentially a successor to the preceding design.

Design of the Ufag C.i was conventional for the time. The biplane wings were of equal span and staggered with the upper assembly ahead of the lower. The wings featured single bays and parallel struts. The engine was fitted to the forward compartment of the slab-sided fuselage, powering a two-blade wooden propeller. The powerplant was a single Hiero 6-cylinder liquid-cooled in-line engine developing 230 horsepower. The pilot sat immediately behind the engine compartment and made use of one or two forward-facing 8mm synchronized machine guns. His observer was seated directly aft and manned a trainable 8mm machine gun of his own. The fuselage tapered into a conventional empennage with large-area horizontal planes and a small-area vertical tail. The undercarriage was fixed and made up of two main landing gear wheels and a tail skid. The landing wheels were situated under the engine compartment, just ahead of the lower wings, and braced with struts.

Performance specifications indicated a top speed of 118 miles per hour as well as a ceiling of 16,075 feet. Engine endurance was limited to 3 hours.

Phonix lent its production talents to the C.I, constructing at least 40 examples of the type.
