The Blohm & Voss P 208 was a study of a single-seat German propeller-driven fighter from 1944.
history
The development of the aircraft began in 1944 - at a time when the jet aircraft era had actually dawned. However, since jet engines did not yet provide the required performance, Blohm & Voss decided to design a fighter with a piston engine. The project was designed so that it could easily be converted to jet propulsion (it was later further developed as a jet-powered fighter under the designation P 212 ). The engine was installed at the stern with a propeller attached without a shaft extension . Rudder, elevator and ailerons were mounted on the wing tips, which improved the tail unit efficiency by 100%. In order to cope with the load from the tail unit, the wings were made of steel shell construction.
Different variants were designed.
P 208.01
For this variant, the use of the Jumo-222 -E-, -F- or -N motor was intended.
P 208.02
For this variant, an AS-413 engine with a maximum of 4,000 hp (composed of two Jumo-213 engines) was provided.
P 208.03
Three design proposals were developed for this variant. P 208.03.01 and P 208.03.02 were to have a DB-603L engine, while a DB 603N was to be installed in P 208.03.03. The dimensions of the three designs were the same and there was hardly any difference in weight.
