Note: This is a sub-section of Sunbeam.

For a year before the outbreak of WWI, Louis Coatalen had experimented with aero-engines

During WWI, until Rolls-Royce started producing aero-engines, Sunbeam were the only British company that was really producing anything considered suitable although even they had problems with vibration.

Sunbeam also built complete aeroplanes at Moorfield Road including the Avro 504Ks, Short Biplanes and some Short land-planes

1917 Sunbeam designed and built their own bomber with a 200 hp 'Arab' engine but it was abandoned soon after

In the late 1920s Coatalen produced a 100 hp engine for aero use but it did not go in to production
