The Focke-Achgelis Fa 284 was a project to develop a large transport helicopter, designed in 1943 by Focke-Achgelis for use by the Luftwaffe.
The helicopter was powered by two BMW 801 radial engines, driving transversely-mounted rotors, and was equipped with a large, detachable cargo pod for carrying loads.
[1] The Fa 284 project was abandoned in late 1943, being replaced by a design for an enlarged version of the Fa 223 featuring a four-rotor arrangement; this project was also abandoned.
