The Focke-Wulf Fw 191 was a twin-engined German bomber prototype from World War II from 1942.
development
In 1939 the Luftwaffe announced a competition for a medium-weight dive bomber (Bomber B program). In addition to Focke-Wulf, Arado ( E.340 ), Dornier ( Do 317 ) and Junkers ( Ju 288 ) also took part in the tender .
The bomber should be able to carry 2000 kg over a distance of 1800 km and reach 600 km / h at an altitude of 7000 m. In addition, there was the requirement for a pressurized cabin to be able to fly over the enemy air defense at great heights . The background to these demands was the idea of being able to reach goals in Great Britain from bases in France and Norway .
The project suffered from engine and electrical problems from the start. Initially, the 2500 hp 24-cylinder Daimler-Benz DB 604 engine was intended as the drive , but neither this engine nor the Junkers Jumo 222 with a similar output, which was later considered , were available in time. The much weaker BMW 801A engines were therefore built into the first prototype .
The first flight took place in 1942. Due to weight problems and poor flight characteristics, only three prototypes were built, the V1 , V2 and V6 . The V6 had two 2200 hp Jumo 222 engines.
The crew of the shoulder- wing decker consisted of five men who found space in the front part of the aircraft nose. The cabin was ventilated with compressed air for great heights. A MG 151 sat under the aircraft's nose , two remote-controlled MG 151s on the fuselage and two remote-controlled MG 81s above the engine pods. A MG 151Z was attached under the fuselage. The bomb bay and brackets under the wings could hold up to 4000 kg bombs or torpedoes .
It was interesting to try to implement the entire control mechanics using electric motors instead of cables and rods (today's designation: fly-by-wire ), which in practice turned out to be very prone to failure.
Development of the Fw 191 was stopped at the end of 1943.
