The Fw 56 was developed, in accordance with a request by the Reich Air Ministry for an advanced fighter trainer, by Kurt Tank, chief engineer with Focke-Wulf. It was also considered for possible use as a home defence fighter.
The first prototype flew for the first time in November 1933. A second prototype had some modifications made to the fuselage, and metal rather than wooden wings for flight testing. The third prototype, which flew in February 1934, reverted to the wooden wing and satisfied the technical designers.
After comparison flights in 1935 against its two competitors - the Arado Ar 76 and the Heinkel He 74 - the Air Ministry ordered production to begin. About 1,000 aircraft were built, mostly used by Germany, though numbers were used by Austria and Hungary. A few were sold for private use, for instance to Gerd Achgelis, who later founded the helicopter company Focke-Achgelis with Henrich Focke.
Ernst Udet, an advocate of the use of dive bombers, demonstrated[1] the second prototype - Fw 56 V2 - in this role, leading to Luftwaffe development of dive bombers.
Design
The Fw 56 was a parasol-wing monoplane aircraft with a fuselage of steel tube construction, clad in metal at the front, and canvas elsewhere. The wing was of wood, covered mostly in plywood, while the trailing edge was fabric-covered. The fixed conventional undercarriage consisted of two cantilever main legs and a tailskid. The aircraft was powered by an air-cooled Argus inline engine and intended as a single-seat advanced trainer for the fledgling pilot trainee to transition to from the Bucher primary trainer. In addition, for its secondary role as an emergency fighter as well as aiding aspiring fighter pilot trainees in conversion, it was fitted with 2 fixed cowl-mounted 7.9mm MG17 machine guns as well as a removable ventral rack for 3 10kg bombs (inert practice bombs or, in the event, light antipersonnel fragmentation bombs)
The Fw 56 was highly popular with pilots,[2] due to its aerobatic capabilities and fine handling. They did think, however, that it had a fragile undercarriage.[3]
