The ADC Nimbus was a British inlineaero engine that first ran in 1926. The Nimbus was developed from the Siddeley Puma aero engine by Frank Halford of the Aircraft Disposal Company, the goal was to develop the Puma to produce its intended power output which Halford eventually achieved. The Nimbus was further developed into an air-cooled version known as the ADC Airsix which did not enter production and was not flown.[1]
