| Barry, 08.01.2010 16:08 There were 6 aircraft built, the last of which, V6, was written off after crashing in July 1937. The first two models V1 and V2 (D-IXAX and D-IBGI)were poweered by the Pratt and Whitney Hornet, licence produced as BMW 132 engines. The third prototype (D-IZIQ) produced at about the same time used a Rolls Royce Kestrel. It became apparent that the radial engine of the first two prototypes was not best suited to the diver bomber role because of the severely restricted forward view and with the coming of the Jumo 210A engine it was decided that this would be the definitive power plant.In 1936 three further prototypes were built V4 (D-IFOE) , V5 (D-IUXU)illustrated, and the ill fated V6 (D-IDTE). These were to be the the Ha137B, the previous 3 being the Ha137A.
There was also plans to produce a model for the German navy useing the Hornet engine. The wheeled version was the P11, as opposed to the Luftwaffe P6, P6a and P6b, and the float version would be the P11b, but with the cancellation of the project no further work was taken. reply |
