This is a list of variants of the Focke-Wulf Fw 190, with detailed descriptions. ==First prototypes== The first prototype, the Fw 190 V1 (civil registration D-OPZE), powered by a 1,550 PS (1,529 hp, 1,140 kW) BMW 139 14-cylinder two-row radial engine, first flew on 1 June 1939. It soon showed exceptional qualities for such a comparatively small aircraft, with excellent handling, good visibility and speed (initially around 610 km/h (380 mph)).〔Shacklady 2005, p. 30.〕 The roll rate was 162° per second at 410 km/h (255 mph), but the aircraft had a high stall speed of 205 km/h (127 mph). The cockpit, located directly behind the engine, quickly became uncomfortably hot. During the first flight, the temperature reached 55 °C (131 °F), after which Focke Wulf's chief test pilot, Hans Sander commented, "It was like sitting with both feet in the fireplace."〔Janowicz 2001, p. 14.〕 Flight tests soon showed that the expected benefits of Tank's cooling design did not materialize, so after the first few flights, this arrangement was replaced by a smaller, more conventional spinner that covered only the hub of the three-blade VDM propeller. In an attempt to increase airflow over the tightly cowled engine, a 10-blade fan was fitted at the front opening of the redesigned cowling and was geared to be driven at 3.12 times faster than the propeller shaft's speed. This quickly became standard on the Fw 190 and nearly all other German aircraft powered by the BMW 801.〔("Illustration of the fan on cutaway drawing." ) ''white1foundation.org.'' Retrieved: 14 August 2010.〕 In this form the V1 first flew on 1 December 1939, having been repainted with the Luftwaffe's ''Balkenkreuz'' and with the ''Stammkennzeichen'' (factory code) RM+CA.〔 The Fw 190 V2, designated with the ''Stammkennzeichen'' alphabetic ID code of ''FL+OZ'' (later RM+CB) first flew on 31 October 1939 and was equipped from the outset with the new spinner and cooling fan. It was armed with one ''Rheinmetall-Borsig'' 7.92 mm (.312 in) MG 17 machine gun and one 13 mm (.51 in) synchronized MG 131 machine gun in each wing root.〔Page 2002, p. 579.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「List of Focke-Wulf Fw 190 variants」の詳細全文を読む スポンサード リンク
