P.Lewis British Aircraft 1809-1914 (Putnam)

Parsons Biplane

   The Parsons Biplane was designed and built by P. M. Muller specially to make use of an automobile engine the greater weight of which, compared with the light-weight aero engines, normally militated against its use in an aeroplane, where every pound was a consideration.
   A two-seat tractor constructed early in 1913, the Parsons Biplane was fitted with the four-cylinder 40 h.p. Aster car engine, which had been lightened slightly and which drove an 8 ft. 2 ins. diameter Normale propeller.
   The design embodied several original features in the hope that stability would thereby be improved. Among them was the extended flexible trailing-edge of the upper wings with considerable overhang of the lower planes. Another was that the fore-part only of the fuselage was covered, in support of the theory that the open framework at the rear would render the rudder more effective. The interplane struts were set close together towards the leading-edge of the wings, thus helping towards the flexing of the rear portion of the chord in the supposed interests of lateral stability. The undercarriage was a straightforward unit of a pair of wheels and twin skids.
   The machine was tested at Brooklands by John Alcock and Jack Humphreys, making a cross-country flight at 2,000 ft. from the aerodrome during May, 1913, when piloted by Alcock.
   Another odd device tried out on the biplane was the J. G. Parsons Pendulum Stabilizer, which consisted of a pair of paddle-wheels, one being suspended in the gap between each pair of wing-tips. The Aster engine installation was not found to be successful and was replaced by a conventional aero engine, the 70 h.p Gnome. In September, 1913, the Parsons Biplane was bought by Noel Pemberton Billing, some of its components forming later part of the Gaskell-Blackburn Biplane of 1914.
