RAF 1

From Wikipedia, the free encyclopedia

The Royal Aircraft Factory 1 was an air-cooled, V-8 engine developed for aircraft use during World War I. It was based on a Renault engine of the time, but featured larger cylinders (3.9 in &times 5.5 in or 100 mm × 140 mm ) for a total displacement of 540 cu in (8.8 L). It was rated at 92 hp (70 kW) at 1,600 rpm.

The heads were cast integrally with the cylinders, but the intake and exhaust valves were set into a detachable section.

In late 1915, the bore was increased to 4.1 in (105 mm) leading to an increased displacement of 590 cu in (9.7 L) and power of 86 kW (115 hp) at 1,800 rpm.
