- Junkers / DFS EF-130
A four engine heavy bomber of ‘Uralbomber’ class designed in the autumn of 1944 to compete against the Arado E-555, the BMW ‘Strahlbomber Projekt II’, the Horten Projekt 18 (23/2/1945) and the Messerschmitt P.1108.
It had a pressurised cockpit for a crew of three, originally designed for the Junkers Ju 388, and the undercarriage of a Junkers EF-131. The wing was a DFS design with leading edge slats, flaps and ailerons.
The system used to power the rotation manoeuvre during takeoff was unknown. It may be speculated that the engines could swing with the help of some hydraulic mechanism to change the thrust direction. That would explain the odd position they are located, in the aerodynamic shadow generated by the cockpit.
The project did not pass the wind tunnel model phase, being cancelled in March 1945.
