Napier Nomad II Model E. 145
An engineering tour-de-force, the Nomad is one of the most complex aircraft engines ever built. The British military needed a high-powered engine for use in long-range aircraft at the end of World War II. Napier designed the Nomad to have the lowest possible fuel consumption by compounding a two-stroke diesel engine with a gas turbine and transmitting the power through a propeller.
The Nomad II, a simplified version of the original design, appeared in 1951 and was intended for the four-engine Avro Shackleton long-range patrol bomber. However, a single Nomad II flew only briefly, in the nose of an Avro Lincoln bomber. Napier cancelled the program in 1955 because the Nomad could not compete with gas turbine engines.
