The V19 ex­per­i­ments

Aviation Classics - - AVIATION -

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.
