The Fokker D.XXIII was a twin-engine fighter aircraft developed in the Netherlands .

history

The D.XXIII was designed by engineer Marius Beeling and when it appeared in 1939, it met with great interest abroad, not least due to the unconventional design of the type. The engines were arranged at both ends of a central fuselage nacelle and each drove a pull and a push propeller. This structural design inevitably resulted in the use of double tail booms. Since there was a risk of possible contact with the rear propeller when leaving the aircraft in an emergency, Beeling even planned to equip the D.XXIII with an ejection seat .

Testing began on May 30, 1939 and it was soon foreseeable that the Walter Sagitta I-SR engine used was too weak, and there were also problems with cooling the rear drive. Fokker therefore considered converting them to Rolls-Royce or Daimler Benz engines, not least because of the expected orders from abroad. When the Netherlands was invaded by the German Wehrmacht on May 10, 1940 , it was also the end of this revolutionary project. The only prototype was destroyed during the Schiphol invasion .

The D.XXIII was designed in a mixed construction, the fuselage was made of metal, the wings arranged in low -wing construction were made of wood. The two tail girders were connected by the horizontal stabilizer. The landing gear was fully retractable. The pilot sat in a closed cockpit.
