Curtiss Model R
__NOTOC__ The Curtiss Model R was a utility aircraft produced for the United States Army and Navy during World War I. It was a conventional, two-bay biplane with slightly staggered wings of unequal span. The aircraft was provided with two open cockpits in tandem and fixed tailskid undercarriage, but many were built for the Navy with twin floats replacing the wheels. During the course of the war, Model Rs were used for general liaison and communication duties, as well for observation, training, and as air ambulances. In practice, the Curtiss powerplants supplied with these aircraft proved insufficient and were mostly replaced with Liberty engines. The Navy's Model R-3 floatplane had extended-span, three-bay wings, and was intended for use as a torpedo bomber. Some of these were later fitted with wheeled undercarriage and transferred to the Army as bombers under the designation Model R-9.

Gee Bee Model R
The Gee Bee Model R Super Sportster was a special-purpose racing aircraft made by Granville Brothers Aircraft of Springfield, Massachusetts at the now-abandoned Springfield Airport. ''Gee Bee'' stands for Granville Brothers. Design and development The 1932 R-1 and its sister plane, the R-2, were the successors of the previous year's Thompson Trophy-winning Model Z. Assistant Chief Engineer Howell "Pete" Miller and Zantford "Granny" Granville spent three days of wind tunnel testing at NYU with aeronautical engineering professor Alexander Klemin. Granville reasoned that a teardrop-shaped fuselage would have lower drag than a straight-tapered one, so the fuselage was wider than the engine at its widest point (at the wing attachment point within the length of the wing chord). The cockpit was located very far aft, just in front of the vertical stabilizer, in order to give the racing pilot better vision while making crowded pylon turns. Operational history The R-1 won t ...

Stinson Model R
The Stinson Model R was an American light aircraft built by the Stinson Aircraft Company in the early 1930s. It was a single-engine high-winged monoplane, developed from the Stinson Junior. 39 units were built. Design and development In 1931, work began on a replacement for Stinson's SM-8 Junior four-seat light aircraft. The new design, the Model R, while based on the SM-8, had a shorter fuselage and a revised cabin. While the aircraft's undercarriage retained the basic tailwheel undercarriage layout of the SM-8, the split-axle mainwheels of the earlier aircraft were replaced by a semi-cantilever design, in which the mainwheels and shock-absorber units were enclosed in streamlined fairings attached to a short stub wing, which was also used to carry wing bracing struts. ''Aviation'' March 1932 p.148. The aircraft had a fabric covered, welded steel-tube fuselage, while the wings were of mixed construction, with spruce spars and steel ribs, covered by fabric.

Wright Model R
The Wright Model R was a single-seat biplane built by the Wright Company in Dayton, Ohio, in 1910. Also known as the Roadster or the Baby Wright, it was designed for speed and altitude competitions. Design The Wright Model R was derived from the Wright Model B, and was a two-bay biplane with rear-mounted twin rudders mounted in front of a single elevator and carried on wire-braced wood booms behind the wing. It was powered by a Wright four-cylinder inline water-cooled engine driving a pair of pusher propellers via chains. Operational history Two examples were flown at the International Aviation Tournament at Belmont Park in November 1910, one being a standard model flown by Alec Ogilvie and the other being a special competition model known as the Baby Grand, which had a V-8 engine and a reduced wingspan of 21 ft 5 in (6.53 m). Orville Wright succeeded in flying the Baby Grand at a speed of nearly . Both aircraft were entered for the second Gordon Benne ...
