Voisin Triplane 1915

  In response to a government requirement for a heavy bomber capable of attacking the German industrial center of Essen, Voisin's team labored day and night for five weeks to produce a monstrous triplane. Testing of the aircraft began in 1915 with Joseph Frantz as test pilot. It was powered by four 270-hp Salmson radial engines mounted back to back in nacelles on the center wing. The fuselage had a partially enclosed cabin for the pilots. A huge rectangular beam extended from just aft of the cockpit through the front of the center and top wings. This structure contained the radiators for all four engines. A second triangular beam connected the top wing with the rudder. The landing gear consisted of three wheels in tandem below the lower wing. A massive nosewheel was semi-recessed in the nose in order to prevent the aircraft from rolling over on landing. The three wings were supported by a complex series of struts. Ailerons were located on the center and top wings and were controlled by two concentric wheels inside the cabin. The outer wheel controlled the ailerons on the top wing; the inner wheel controlled the ailerons on the center wing. The latter were used only to compensate for asymmetric flight as a result of engine failure.
  The aircraft, named the J. Benoist - L. Mijduant, was the first four-engine aircraft to fly in France. It was presented to the army on 15 August, 1915. The military authorities saw the aircraft not as a heavy bomber capable of smashing Essen, but as a slow-moving behemoth that would present an easy target for anti-aircraft artillery. After examining the other entrants in the 1915 concours, the pilots and organizers agreed to another competition.
  The efforts of the Voisin team had been wasted and the triplane was dismantled. However, Voisin did not yet abandon the triplane layout and used the wings from the 1915 bomber to produce his next heavy bomber, the 1916 E.28.
