Patrol Bomber flying-boat

P.Bowers Curtiss Aircraft 1907-1947 (Putnam)

Model T (Wanamaker Triplane, Model 3)

   At the time of its construction in 1915-16, the Curtiss Model T flyingboat, which was instigated by Rodman Wanamaker of America fame, was the largest seaplane in the world. It was also the first four-engined aeroplane built in the United States. An unusual feature was the arrangement of the engines-four 250 hp Curtiss V-4 tractors in a straight line, a feature used successfully up to that time only by the Russian Sikorskys and the single German Siemens-Forsman. Because of marginal directional control under one-engine-out conditions, designers usually grouped engines as close to the aeroplane centreline as possible to minimize the turning couple of an unsymmetrical power condition. A favourite procedure was to pair two side engines in tandem installations in a single nacelle, which Curtiss did on the C-2 in 1919.
   The America-type control cabin was equipped for two pilots and an engineer. The control forces were so great that an early form of power boost was provided. Small windmills installed on the wings were connected to the aileron cables by electrically-operated clutches. The power of the windmill was imparted to the cable to aid the pilot. Similar devices were used for the tail controls.
   The T was designed to requirements of the British Admiralty, which ordered 20 examples, RNAS serial numbers 3073/3092. While the first T was assembled inside the Buffalo plant, it was not flown in the US because the V-4 engine was not developed in time. The aeroplane was shipped to Britain without engines and 240 hp French Renaults were installed there.
   The big triplane was not put into service and the remaining 19 on order were cancelled. The basic design concept was retained, however; the Curtiss Model T was the direct predecessor of the five-engined Felixstowe Fury triplane that Cmdr Porte designed for the Admiralty.
