Pierce Sporting Tractor Biplane

03/31/2013. This small single-seater tractor biplane was designed to meet the requirements of the sportsman by Samuel Stillman Pierce, assisted by Charles Lawrence and Sydney S. Breese. The aircraft was constructed in late 1916 at the S.S. Pierce Aeroplane Company of Southampton, as was 35-40 hp Pierce three-cylinder air-cooled radial engine, that directly drove a 7 ft (2.13 m) Paragon screw with a 3 ft 6 in (1.07 m) pitch. The exhaust from the engine was led through pipes below the lower wing.

The fuselage of circular streamline form was mounted 6 in (15 cm) above the lower wing on the central interplane struts. The unequal span wings staggered 1 ft (30 cm) and were set at 4 incidence, lateral control was by ailerons on the top wing. The tail planes were of somewhat unusual design, the main horizontal surface, which were semi-circular in shape and served as the elevator, was pivoting on a small horizontal surface projecting from the sides of the rear extremity of the fuselage.

A V-type landing chassis was used, carrying a pair of 26x4 in (66x10 cm) wheels, 4 ft 4 in (1.32 m) apart. Additional photo (site files)
