Messerschmitt Me 262A-2a with Lorin Ramjets (Matchbox and Scratch-built)

TYPE: High-altitude interceptor

ACCOMMODATION: Pilot only

POWER PLANT: Two Junkers Jumo 004B turbo-jet engines, rated at 890 kp each plus two Lorin ram-jets, rated at 1,350 kp each

PERFORMANCE: 714 mph (estimated)

COMMENT: Dr. E. Sänger, a convinced supporter of ram-jet powered aircraft, e. g. Skoda-Kauba SK P. 14-01 and SK P.14-02, proposed to increase the performance of a Messerschmitt Me 262 by integrating two additional Lorin ram-jets. The ram-jets, each 5.90 m long, were mounted above the wing resp. the turbo-jet engines, the air intake was 45.1, and the exhaust pipe 85 cm in diameter, respectively. It was calculated that the Me 262 could reach 48,557 ft within 11.5 minutes. Finally, this project was not pursued (Ref.: 19)
