Martinsyde F.4 Buzzard

1918 WORLD WAR 1

Martinsyde F. 4 The Vulture's Tale

The Martinsyde F.4 "Condor" was a British-designed single-seat combat biplane introduced in the final months of the First World War. Although the war saw no direct combat action, the type continued to be stationed in the RAF and several other national air services in the years that followed. The Condor was one of the fastest biplanes to emerge during the war, and while about 1,500 were ordered, only 57 were produced, for a total of about 100 produced by the end of the armistice in November 1918.

A total of 370 aircraft were eventually completed.

The Martinsyde Group was formed in 1908 as a joint venture between HP Martin and George Handasyde to form "Martin and Handasyde". During the first few years, the company developed several types of aircraft (mainly monoplanes) before the outbreak of World War I in the summer of 1914.

Since then, the company has grown into one of the largest British aircraft manufacturers of the war. In 1915, the surnames of Martin and Handaside were merged into "Martinside".

As a private venture capital program, George Handasyde designed a new biplane in 1917, later known as the "Martinsyde F.3". Powered by a Rolls-Royce Falcon V12 engine, the aircraft had powerful performance figures that surpassed many fighter types of the time.

The F.3 made its first flight in November 1917, and formal evaluation piqued the interest of the RAF, leading to the ordering of 6 experimental mounts and an additional 150 production-quality forms. Very fast by 1917 standards, at 140 mph, the prototype was designed to fundamentally render all previous fighter forms obsolete.

However, the introduction of the F.3 to the RAF also posed a problem, with Rolls-Royce Falcon engines being used in warfare elsewhere. As a result, the Hispano-Suiza 8Fb 300 hp engine was replaced, resulting in the "F.4" designation to denote this change.

The aircraft was nicknamed "The Condor", forming the full name "Martinsyde F. 4 Buzzard".

The appearance of the Buzzard was very traditional for its time, with a two-wing layout with wing assemblies above and below the single-seat fuselage. The wing design includes a single cabin and staggered parallel struts. The fuselage itself consists of sloping surfaces that promote a pleasing aerodynamic shape. The front end houses a Hispano-Suiza V engine that turns a two-bladed propeller via an aerodynamic spinner assembly. The pilot sits in the open-air cockpit behind a small windshield, just below and behind the upper wing section.

The landing gear is static and has two wheels with rear skids. The armament consisted of a pair of 7.7mm Vickers-type machine guns that fired synchronously through rotating propeller blades.

Full performance specs include a top speed of 146 mph, a top speed of 24,000 feet and 2.5 hours of battery life.

The end of the war limited the Vulture's potential wartime range, although it did appear in other modifications and in the inventories of many foreign operators. Variants include a two-seater cruiser, a four-seater airliner, a seaplane, and a two-seater long-haul airliner.

Notable operators include Finland, Latvia, Lithuania, Portugal, Spain and the Soviet Union. Interestingly, after the armistice, the RAF lost much interest in the Condor and all unfinished contract airframes were cancelled - only those remaining on the assembly line were completed as planned.

Had the war continued beyond 1918, the Martin West German Condor would certainly have played a major role in the campaign planned in 1919. Surprisingly, some condors were still in service (those with the Latvian Air Force) in the years leading up to World War II. In the years following the First World War, the Martinside Group focused on the production of civilian motorcycles.

However, a factory fire eventually led to liquidation and the company ceased to exist in 1922.
