Kaproni Bulgarski KB-11 Fazan
The Kaproni Bulgarski KB-11 Fazan ((英語:Pheasant)) was a 1940s Bulgarian army liaison and utility monoplane built by Kaproni Bulgarski, a subsidiary of the Italian aviation conglomerate Società Italiana Caproni.
==Development and design==
The prototype Fazan flew in 1941 as a shoulder-wing monoplane powered by a Alfa Romeo 126 R.C.34 radial engine.〔 It had a fixed conventional landing gear with a tailwheel. Flight testing of the prototype showed that the aircraft was unstable and was nose-heavy in level flight, and was considered unsafe during forced-landings. By analogy with the Hunchback of Notre-Dame, the prototype gaining the unflattering nickname "Quasimodo".〔Bernád 2001, p. 16.〕
The second prototype was redesigned with a high-wing, a revised undercarriage and new cockpit glazing, while retaining the engine and three-bladed fixed-pitch propeller of the first prototype. The revised aircraft successfully passed its flight trials, and a small batch of six similar aircraft, designated KB-11-I, followed.〔 While this batch was being built, a further-revised version was produced, the KB-11-II. This took advantage of the availability of large quantities of PZL-license built Bristol Pegasus engines that had been captured by the Germans during the Invasion of Poland, with a Pegasus XXI driving a two-bladed wooden propeller replacing the Alfa-Romeo, while the fuselage glazing was changed again. This revised aircraft was renamed Fazan, and was followed by 43 production aircraft.〔
