BFW M.22
The BFW M.22 was a twin-engined medium bomber designed by Willy Messerschmitt for the German Ministry of Transport. It was one of only two biplanes Messerschmitt designed, both unsuccessful.
Development
During 1927, following the success of his M.18 airliner tried to gain funding from the Baverian government; because the latter were already subsiding BFW (Bayerische Flugzeug-Werke) they pressed for an arrangement whereby Willy Messerschmitt joined BFW on the understanding the company produced only his designs. During these negotiations, completed on 8 September 1927, the Ministry of Transport put pressure on Messerschmitt to produce military aircraft. This led to the only two biplanes Messerschmitt ever designed, the second of which was the BFW M.22 medium bomber, otherwise known as the Messerschmitt M 22.
It was a twin-engined biplane, with broad chord I-form interplane struts and ailerons on both wings. It had a conventional tail with an externally braced tailplane. The upper wing was raised above the fuselage by a long faired pylon, which separated the forward pilot's cockpit and the nose gunner's position from a dorsal gunner's position. The main undercarriage was a wide track split axle design, with the main wheels in spats; there was a tailskid.
