history

P 300 in April 2018 at the Aero Friedrichshafen

The development of the P 300 began in 1967 by the aircraft designer Günter Pöschel, who was born in 1937 . It should be an amphibious aircraft with a pressurized cabin for six to eight passengers, which should also be used as a feeder or touring aircraft. The first design was a high-wing aircraft with a towing propeller installed on a T-tail unit , which was driven by a long-distance shaft with a deflection gear from a Lycoming TIO 541 engine installed behind the cabin . The first flight took place on February 27, 1971 at the DFVLR in Oberpfaffenhofen. The flight tests revealed considerable problems with the long-distance shaft and the arrangement of the propeller, so that the machine was shut down in 1975 despite some modifications. The second prototype was fitted with a turboprop -Triebwerk Allison 250-B17b equipped with 308 kW and as Pöschel P 400 A1 Turbo equator called. The machine with the registration D-EMFG took off on its maiden flight on August 24, 1977 and was destroyed in an accident during the eighth test flight on November 5, 1977. In the third prototype, Pöschel tried to improve the efficiency of the drive and installed the drive of the machine with three-bladed pusher propeller, which had now been redesigned to a middle-decker, in a gondola above the center of gravity of the machine. The machine, built in 1979 as the P 300B1, was exhibited at the ILA in Hanover in 1982 . The flight tests and series production did not take place, however, because Pöschel had run out of funds.

After 30 years of standing outdoors at the Erbach airfield near Ulm, the D-EALM was cleaned and repainted in April 2018 at the Aero Friedrichshafen . Then she should come to the Deutsches Museum .

construction

The P 300 was a small flying boat and amphibious, of which several constructively different prototypes were built. The last version of the GRP construction used an aerodynamically clad motor in a pylon arrangement and was equipped with a nose wheel retractable landing gear. In addition, they had a system for influencing the boundary layer to reduce the landing speed. The good properties as an amphibian resulted from the design of the aerodynamically optimized fuselage shape and the aerodynamically perfectly smooth wings with slotted flaps . It was planned to equip the machine with Pratt & Whitney PT-6A-27 propeller turbines or two piston engines (2 × 210 WPS) in tandem. In total, the machine was to be offered in 51 equipment variants.
