The Hamilton H-45 and H-47 were six-passenger-seat, all-metal, high-wing monoplanes powered by single Pratt & Whitney radial engines . They were built for passenger and mail-carrying work in the US in the late 1920s.

36-647: The US Navy awarded Wright a contract to develop two new air-cooled radial engines. The first, called the P-1, was a 9-cylinder single row design of 1,652 cu in (27.07 L) displacement that was derived from an earlier Lawrence design, it produced 400 hp (300 kW). The second, the P-2, had the same 1,652 cu in (27.07 L) displacement as the P-1, but was an improved design that produced 435 hp (324 kW). Neither engine entered production, with
48-693: The Wright Aeronautical Corporation and used in numerous American aircraft in the 1930s, 1940s and 1950s. The Wright Aeronautical Corporation was formed in 1919, initially to develop liquid-cooled Hispano-Suiza V8 engines under license. In 1923 the Wright purchased the Lawrance Aero Engine Company , and with the purchase Charles Lawrance came to Wright as the Vice-President. Later that year
60-775: The Atlantic to the Pacific between respectively Cristóbal, Colón and Balboa in the Panama Canal Zone . The airline impudently claimed the 30-minute flight as the "fastest transcontinental service in North America". One H-47 (originally built as an H-45) was impressed by the United States Army as a UC-89 in 1942. It was found unsuitable for Army work and was struck off charge in August 1943. It
72-647: The H-45 and the H-47 were powered by a single, uncowled, Pratt & Whitney 9-cylinder radial: the H-45 had a 450 hp (335 kW) Wasp and the H-47 a 525 hp (390 kW) Hornet . The Hornet gave a 10 mph (16 km/h) increase in cruising speed and a slight (3%) increase in useful load to 2300 lb (1043 kg). Both types first flew in 1928. Both could be mounted on floats. In all, about 25 H-45s and 21 H-47s were built. The H-45 and H-47 were used from 1928 to operate passenger and mail services within
84-577: The Navy selecting the superior Pratt & Whitney R-1340 Wasp , so in 1926 work started on the improved 1,750 cu in (28.7 L) design, which became the R-1750 Cyclone. R-1300 Cyclone 7 (1942) R-1750 Cyclone (1926) R-1820 Cyclone (1932) R-2600 Cyclone 14 (Twin Cyclone) (1935) R-3350 Cyclone 18 (Duplex Cyclone) (1937) R-4090 Cyclone 22 Note:
96-524: The US. Northwest Airways flew at least nine aircraft, introducing them on their Chicago-Minneapolis/St Paul route CAM 9 from September 1928. Other U.S. airlines to use the type for both passengers and cargo were Coastal Air Freight and Condor Air Lines . Wien Airways of Alaska used at least one H-45 on a route from Fairbanks to the western coast and on to Point Barrow . During 1930, Isthmian Airways used Hamilton floatplanes for their service linking
108-492: The earliest all-metal US aircraft. The H-45 and the H-47, which differed chiefly in having a more powerful engine, were part of that series. Both types were corrugated-aluminium-skinned in the Junkers style. The high wings were semi-cantilevers, unsupported apart from pairs of parallel struts from the fuselage bottom edge to the wing close to the fuselage. The main legs of the fixed, tailwheel undercarriage were attached at
120-414: The same wing points as the struts and joined laterally by inverted V bracing. The fuselage was flat-sided, with wide windows to the passenger cabin under the wing. This was accessed via a portside door, aft of which was a smaller door into a baggage compartment. The two crew members sat in a cabin in front of the wings, accessed by a rooftop hatch. The tail was conventional, with a braced tailplane. Both
132-551: Was a featured aircraft in Howard Hawk's 1939 "Only Angels Have Wings" flying mail for "Barranca". The flying scenes were fake; however, the aircraft was used in ground scenes. The movie prop model (or one of them) survives. H-45 Wasp powered, ~25 built. H-47 Hornet powered, 20 built. H-47 Special 525 hp (390 kW) Wright Cyclone powered, span extended to 60 ft 5 in (18.4 m). One built. UC-89 Single impressed aircraft. One H-47 remains flyable. N879H
