Perry-Beadle Flying-boat

  Perry, Beadle and Co.'s exhibit at the 1914 Olympia Aero Show was a small two-seat biplane flying-boat of good workmanship and neat appearance. Several unusual features were incorporated in the design, including the mounting of the eight-cylinder 60 h.p. E.N.V. "F" engine in the bows, whence its power was transmitted to the pair of outboard Integral propellers through chains and sprockets. The hull was made by S. E. Saunders and Co., of Cowes, on their Consuta system of two skins of mahogany sewn together with copper wire. The tailplane and fin were made integrally with the hull, and the tailplane and the mahogany-covered lower wings rested in the water to support the machine when at rest. Such unorthodox innovations in design did not prove to be very practical and, after unsuccessful tests on Lake Windermere, the machine was broken up. Span, 35 ft. Wing area, 285 sq. ft. Weight empty, 950 lb. Maximum speed, 64 m.p.h.

Perry Beadle (Perry, Beadle and Co.). (42.)

  ANOTHER newcomer to the Show will be the flying boat exhibited by Messrs. Perry, Beadle and Co.
  This machine differs materially both in design and construction from usual practice. From the accompanying sketch it will be seen that the lines of the boat itself are highly original. In front it is very deep and wide, and in this portion of it is housed the engine, a 60 h.p. E.N.V., which drives through chain-and-sprocket gearing the two propellers situated in front of the main planes.
  The tail planes are fish-shaped and form a continuation of the boat itself, being of the same material, that is to say, two layers of mahogany. The most interesting point, however, is perhaps the position and construction of the lower main plane. This member is covered with mahogany similarly to the boat, instead of the usual fabric covering, and is partly submerged in the water when the machine is at rest.

  THE flying boat exhibited by this firm is of very unusual appearance and represents radical changes from accepted methods of flying bout design. The boat itself, which has been built by Messrs. Saunders, of Cowes, has two skins of mahogany sewn together with copper wire, The tail planes, which are more or less fish-shaped, form a continuation of the hull, and are built up in the same way.
  The pilot's and passenger's seats are arranged tandem fashion, the pilot occupying the rear seat. Control is by means of a hand-wheel mounted on a single central column, and a pivoted foot-bar.
  Mounted in the nose of the boat on strong longitudinal bearers, the engine - a 60 h.p. E.N.V., is temporarily fitted, but will be replaced later by one of higher horse-power - driving through chain and sprocket gearing the two propellers, situated in front of the main planes. These propellers seem to be of very small diameter, but are really nearly six feet. The combined thrust and journal bearing is supported in a steel casing, which is in turn mounted between the two halves of the front plane strut, the whole being made rigid by the diagonal cross bracing wires. This, of course, necessitates very careful adjustment of the wires, as otherwise the propeller shaft would be out of truth. A very neat streamlined casing of brass encloses the propeller shaft in the manner shown in one of the accompanying sketches. The tubular chain guards serve at the game time as radius rods by taking the compression due to the pull on the chains.
  The main planes are separated by hollow spruce struts, and the upper one, which is covered with fabric in the usual way, carries the interconnected aileron. The lower main plane, the trailing edge of which is submerged in the water when the machine is at rest, is covered with two skins of mahogany sewn together, similar to the covering of the boat. No wing tip floats are fitted as the lower plane performs this duty. The arrangement, whilst very unusual, is certainly well worth trying, but one would imagine that for work in a rough sea several objections might be raised against it.
  The construction of the boat, as one would expect from a firm like Messrs. Saunders, is excellent.
