The Johns Multiplane was a very large unsuccessful experimental aircraft having seven wings and six ailerons, powered by three Liberty L-12 V-12 aircraft engines. The machine had the appearance of a biplane spliced onto the front of a triplane with two wings added at the rear. The center fuselage housed the cockpit and one engine in tractor configuration. Both side booms ended with wing-mounted engines in pusher configuration. The aileron control force was found to be extremely high.

Design and development

Designed by Herbert Johns of the American Multiplane Company in Bath, New York, Patent # 1,365,995 Flying Machine was granted to Charles A. Herrmann, also of the American Multiplane Company on Oct. 3, 1916. [1]

Operational history

The massive septi-wing made a series of short hops during testing, but was eventually scrapped in 1920 [2] due to its inability to maintain controlled flight.

<span class="mw-page-title-main">Aileron</span> Aircraft control surface used to induce roll

An aileron is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft. Ailerons are used in pairs to control the aircraft in roll, which normally results in a change in flight path due to the tilting of the lift vector. Movement around this axis is called 'rolling' or 'banking'.

The Wright Flyer made the first sustained flight by a manned heavier-than-air powered and controlled aircraft—an airplane—on December 17, 1903. Invented and flown by brothers Orville and Wilbur Wright, it marked the beginning of the pioneer era of aviation.

<span class="mw-page-title-main">Airplane</span> Powered aircraft with wings

An airplane or aeroplane, informally plane, is a fixed-wing aircraft that is propelled forward by thrust from a jet engine, propeller, or rocket engine. Airplanes come in a variety of sizes, shapes, and wing configurations. The broad spectrum of uses for airplanes includes recreation, transportation of goods and people, military, and research. Worldwide, commercial aviation transports more than four billion passengers annually on airliners and transports more than 200 billion tonne-kilometers of cargo annually, which is less than 1% of the world's cargo movement. Most airplanes are flown by a pilot on board the aircraft, but some are designed to be remotely or computer-controlled such as drones.

The Fairey Spearfish was a British carrier-based, single-engined, torpedo bomber/dive bomber that was ordered from Fairey Aviation for the Fleet Air Arm during World War II. Designed during the war, the prototype did not fly until July 1945. Much larger than earlier naval bombers, it was designed for use aboard the large Malta-class aircraft carriers that were cancelled after the war and was itself cancelled thereafter. Seven prototypes were ordered, but only five were built, of which four actually flew. They were mostly used for experimental work until the last aircraft was scrapped in 1952.

The Gallaudet D-2 was a prototype American biplane observation aircraft built by the Gallaudet Aircraft Company during World War I for the United States Army. Based on the earlier Gallaudet D-1, the D-2 had more powerful engines and had other improvements. The first prototype was completed in 1917, but crashed before it was accepted so Gallaudet had to build a replacement at its own expense. Two aircraft were completed in 1918, but further development ceased after the last one crashed with the death of the pilot, the first aviator to be killed in Rhode Island. All aircraft built or in the process of being constructed were subsequently scrapped.
