P.Lewis British Aircraft 1809-1914 (Putnam)

Martin-Handasyde Military Monoplane

   During 1912 the War Office ordered four examples of a new military monoplane from Martin and Handasyde. Two were delivered, but neither was flown after receipt. The machine was of the two-seat tractor type and was powered by the eight-cylinder 65 h.p. Antoinette engine. The firm regarded the Antoinette as a good power plant, and returned to using it after testing the Gnome and J.A.P. units in their other designs. The machine still embodied typical features of the 1909 type of Antoinette monoplane some two years after such a style had been in its heyday.
   The triangular-section fuselage accommodated its crew in tandem in one undivided cockpit. The engine was cooled through the medium of aluminium tubing condensers, 13 ft. 6 ins. in length and nearly 70 sq. ft. in area, which were mounted on the sides of the fuselage. A steel tube of large diameter, incorporated in the fuselage just forward of the C.G., formed the central support for the strong undercarriage unit. The main tube carried inside it the rubber shock-absorbing system. The engine was given an aluminium cowling, which fitted it closely, and the rest of the fuselage was plywood-covered for strength over its four longerons. A great improvement over the previous Martin-Handasyde designs was the provision of a coaming about the cockpit area, bestowing reasonable protection for the occupants. Warping lateral control was applied to the wings, the tips of which were also washed-out for better automatic stability.
   An improved version of the type, fitted with the more powerful eight-cylinder 80 h.p. Laviator engine, was exhibited at the 1913 Aero Show at Olympia.

Martin-Handasyde Military Trials Monoplane

   The Military Trials Monoplane of 1912 was entered as No. 17 and was similar in appearance to the military monoplane produced for the War Office. The machine seated two in tandem in separate cockpits and was fitted at first with an 80 h.p. Dansette-Gillet engine, which was replaced by the 90 h.p. Chenu for the Trials, during which C. Gordon Bell was the pilot. The next engine used was a 65 h.p. Antoinette, and this was followed in 1913 by a 120 h.p. Austro-Daimler, which gave a top speed of 75 m.p.h. On 13th June, 1913, the machine was crashed by Bell at Brooklands during low flying, killing the passenger, Lt. J. R. B. Kennedy. Span, 42 ft. Length, 38 ft. Weight empty, 1,250 lb. Weight loaded, 1,800 lb. Maximum speed, 75 m.p.h.


Martin-Handasyde 1913 Monoplane

   Similar in appearance to the 1912 Military Trials two-seater, this machine was completed at Brooklands in August, 1913, being tested during the following month by R. H. Barnwell and taking second place in the second Aerial Derby on 20th September, 1913. The engine was the 120 h.p. Austro-Daimler, and the machine was flown by Barnwell in the London- Brighton-London race of 8th November, 1913. At the end of the year it was modified with a pair of small wheels on the front of the undercarriage skid. The centre undercarriage pylon was faired to a streamline section. Early in 1914 the machine was being flown at Brooklands by 2nd Lt. Vincent Waterfall, who had gained his Royal Aero Club Aviator's Certificate No. 461 on 22nd April, 1913, on a Vickers at Brooklands. A speed of 97 m.p.h. was recorded with the aircraft in a test carried out at Farnborough. In February, 1914, it was involved in an accident when the small front wheels of the undercarriage came off and smashed the propeller.


Martin-Handasyde Waterbus

   The Waterbus Monoplane was reported to be under construction by Martin and Handasyde at Brooklands during 1913.
