The V19 experiments
While the Fw 190B and C programmes were based on the development of new engines – particularly the DB 603 and Jumo 213 – these were by no means the only engines investigated by the company during the summer of 1942. A generic designation of ‘V19’ was used to examine how an array of different powerplants might suit an aircraft approximately based on the Fw 190A-2. Among these were the 801 J and P 8028 from BMW, and the DB 609, DB 614 and DB 609 from Daimler-benz. The BMW 801 J was a turbosupercharged version of the D-2, where the turbosupercharger was substantially lowered within the airframe to make it fit.this was expected to produce 1785hp at sea level. Development was slow and progressed only as far as the completion of two engines for experimental installation into a Junkers Ju 88. The BMW P 8028 was meant to produce 1550hp at high altitude and although there was expected to be some difficulty in fitting it, it was still likely to be more easily installed than the BMW 801 J. It seems unlikely that the engine was ever completed. The enormous 16-cylinder DB 609 was intended to produce an incredible 2660hp. In order to balance the Fw 190’s centre of gravity, it would have been necessary to fit a pair of large radiators just aft of the cockpit – weakening the airframe’s overall structure considerably in the process.the engine was cancelled in 1943. The more modest DB 614 was to generate 1810hp but was also extremely heavy, altering the aircraft’s centre of gravity. This fitment for V19 was only given a cursory evaluation before being rejected. Finally, the DB 623 was intended to make 2265hp thanks to a pair of turbosuperchargers. Unfortunately, it had a very large diameter when fitted which meant the Fw 190’s fuselage would have had to be unusually deep. Plans to use it on the Fw 190 were dropped in January of 1943.
