Messerschmitt Bf 109TL
|National origin||Nazi Germany|
The Messerschmitt 109TL was a turbojet fighter designed in 1943 by the Messerschmitt company for the Luftwaffe during World War II. It was an alternative twin-jet design proposed as a backup for the Messerschmitt Me 262.
Design and development
It was first proposed on 22 January 1943 at an RLM conference; at the time only three prototypes of the Me 262 had been completed. The Bf 109TL would be a backup if the Me 262 did not come to production or as a second fighter to operate alongside the Me 262.
In order to reduce development time, various components from previous aircraft were to be used. The fuselage was to come from the Bf 109H/BV 155B high-altitude fighter (with a new nose and tail section), the wing was from the Me 409 project and the tricycle undercarriage came from the Me 309. The powerplant would be the same Junkers Jumo 004B-1 turbojet (900 kgf thrust) or BMW 003A (800 kgf).
The basic armament was to be two 20 mm MG 151/20 cannons (with 120 rpg) and two MK 103 cannons mounted in the nose. An additional proposal was two 30 mm (1.18 in) MK 108 cannons to be installed in the wing roots. The pilot cockpit used in the prototypes was the same as utilized in the Bf 109E/G types.
The performance was estimated to be possibly better than the Me 262 due to the Bf 109TL's narrower fuselage, a product of the design for a high-speed high-altitude fighter. The Bf 109TL received intensive research. By March 1943, it was decided that many other modifications to components would be needed and the project was abandoned in order to concentrate on the Me 262 project.
