Back Focke-Achgelis Fa.225


This rotary wing glider consisted of the fuselage of a DFS.230 glider, the wings of which have been replaced by an Fa 223 rotor. With a gross weight of 905kg, it was to be hauled at a speed of about 190km/h by a Ju-52, and would then be able to land within not more than 18 metres. During World War II this glider was never put to practical use. Rotor diameter - 12m.

During the first half of the Second World War, the assault glider was of considerable importance in the rapid landing of troops and supplies, but its use was dependent on the availability of sufficient landing area. Where the landing area was restricted by natural or artificial obstacles, the glider's landing run could be shortened by nose braking rockets, although the landing approach remained unaltered. The idea therefore arose of exploit-ing the almost vertical or very steep descent to be obtained from rotary wings in autorotation, and in 1942 the fuselage of a DFS 230 glider had its fixed wings replaced by an Fa 223 three-blade rotor mounted on a structural pylon. To take the increased landing load, a braced undercarriage replaced the normal skid. This hybrid rotaglider, designated Focke Achgelis Fa 225, was towed behind a Junkers-Ju 52/3m in tests, during 1943, and could land within a distance of 18 m (59 ft). It was not, however, put to operational use, probably because of changing operational requirements, and possibly because its advantages were counterbalanced by the fact that the towing speed was considerably lower than that of the standard DFS 230, and it would have been more vulnerable to attack with its slower assault approach speed.
