- Sunbeam Crusader
The Sunbeam Crusader was an early British side-valve, water-cooled V8 aero engine first marketed in 1913.
Design and development
It was fitted to a Farman biplane for flight testing piloted by John Alcock (who would later participate in the first aerial non-stop crossing of the Atlantic Ocean). In its original form, it developed 120 hp (90 kW) at 2,500 rpm, but production examples were rated at 150 hp (112 hp) at 2,000 rpm. Its bore was 3½ inches (90 mm), it had two valves per cylinder, and weighed 480 lb dry. The engine was used in a wide variety of British military aircraft during the first years of World War I, most notably the Short 827 seaplane for which six of the original versions were ordered followed by 107 of the more powerful type.
