A purely experimental model built for the Army Air Forces, the XR-8 has the advantages of greater power efficiency, reduction of vibration, reduced drag, and reduced power transmission requirements. Kellett helicopter with twin intermeshing rotors. This prototype first flown 7 August 1944. One XR-8 and one XR-8A built. Programme cancelled by US Army in 1946, but at least one of the helicopters was still being flown in 1947.

The XR-8 was an experimental American helicopter built by the Kellet Autogiro Corporation. It first took flight in 1944. Despite the fact that it was built by an autogiro company, it is in fact a helicopter and is a result of Kellet realizing that the future of rotary aircraft would be in the form of helicopters.
