Focke-Wulf Super Lorin
To solve the problem of the excessive landing speed of the Ta 283, the project team led by the Dipl.-Ing.von Halem sent to the OKL the dossier Baubeschreibung Nr.246 describing a short-span STOL variant of the Super TL with an auxiliary turbojet providing vertical lift, one bi-propellant rocket and two ramjets. This project has been commonly described in the literature as Focke-Wulf Super Lorin
Built in light alloy, the fuselage housed the pressurized cockpit with ejector seat, two MK 108/30 heavy cannons, the landing gear, one 270 litre tank containing the B.4 petrol for the turbojet, two K1 heavy kerosene fuel tanks of 650 and 845 litres for the ramjets, one C-Stoff rocket propellant tank of 345 litres, one T-Stoff rocket propellant of 575 litres, one HeS 8 turbojet with 720 kp static thrust and one bi-propellant rocket Walter 109-509 A-1 rocket with 1,700 kp peak thrust. The wings, spanning 7.6 m and with a 15 sq. m area, were built in wood/plywood/steel and housed six K1 fuel tanks with 150 litres each.
The tail planes were built of steel and served as support for two Pabst ramjets of 10,850 kp thrust each. The landing gear was of the same type than that developed for the Super TL. The exhaust nozzle of the turbojet was located on the fuselage belly to the purpose of generating lift thrust during take-off and landing. High altitude performances could also be improved, although a shorter wing span might make the airplane very fast at lower altitude, where the ramjets could produce the maximum thrust.
