TypeEight-cylinder water-cooled inline aircraft engine
National origin Italy
Manufacturer Isotta Fraschini
First run1915

The Isotta Fraschini V.5 of 1916 was an Italian eight-cylinder, water-cooled, in-line piston aero engine of World War I. The "V" denoted "Volo" or "flight" rather than piston arrangement. [1]

World War I 1914–1918 global war originating in Europe

World War I, also known as the First World War or the Great War, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. Contemporaneously described as "the war to end all wars", it led to the mobilisation of more than 70 million military personnel, including 60 million Europeans, making it one of the largest wars in history. It is also one of the deadliest conflicts in history, with an estimated nine million combatants and seven million civilian deaths as a direct result of the war, while resulting genocides and the 1918 influenza pandemic caused another 50 to 100 million deaths worldwide.

Design

The V.5's construction was fairly typical of aircraft engines of the period with cast-iron cylinders mounted in pairs with common heads and water jackets. It had much in common with the six-cylinder Isotta Fraschini V.4 and was built at a similar time. Though powerful, it was very heavy and thus, like some other Isotta Fraschini engines, better suited to airships than aircraft. [1]

Isotta Fraschini V.4 I-6 piston aircraft engine

The Isotta Fraschini V.4 of 1916 was an Italian six-cylinder, water-cooled, in-line piston aero engine of World War I. Its construction was fairly typical of aircraft engines of the period with six cast-iron cylinders mounted in pairs with common heads. This engine was also produced by Alfa Romeo.

Airship type of aerostat or lighter-than-air aircraft

An airship or dirigible balloon is a type of aerostat or lighter-than-air aircraft that can navigate through the air under its own power. Aerostats gain their lift from large gasbags filled with a lifting gas that is less dense than the surrounding air.

General characteristics

Components

Valvetrain mechanical system that controls operation of the valves in an internal combustion engine

A valvetrain or valve train is a mechanical system that controls operation of the valves in an internal combustion engine, whereby a sequence of components transmits motion throughout the assembly.

Overhead camshaft valvetrain configuration

Overhead camshaft, commonly abbreviated to OHC, is a valvetrain configuration which places the camshaft of an internal combustion engine of the reciprocating type within the cylinder heads and drives the valves or lifters in a more direct manner compared with overhead valves (OHV) and pushrods.

Ignition magneto electricity-producing device

An ignition magneto, or high tension magneto, is a magneto that provides current for the ignition system of a spark-ignition engine, such as a petrol engine. It produces pulses of high voltage for the spark plugs. The older term tension means voltage.

The Rolls-Royce Exe, or Boreas, was a 24-cylinder air-cooled X block sleeve valve aircraft engine intended primarily for the new Fairey Fleet Air Arm aircraft, particularly the Fairey Barracuda. The Exe was relatively powerful for its era, producing about 1,100 hp. This is notable given the relatively small 22 litres displacement, the Merlin requiring 27 litres for approximately the same power level. The X-24 layout made this quite a compact engine.

The pilot and observer sat in tandem, open cockpits. A single prototype of a long-range example, originally designated A.7 Raid and later A.16 was also constructed, but the air force showed no interest in it.
