Do-335 "Pfeil"




The Do-335, often referred to as the Pfeil "Arrow", had an unusual engine layout. The design of this aircraft was based on a tandem engine layout, patented by C. Dornier in 1937, although this scheme has been known since the First World War - it was used on the Fokker K-1 and Siemens-Schukert DDr-1.

The aircraft had an unusual cruciform tail. Tricycle landing gear, the front support retracted back into the front of the fuselage. The aircraft is equipped with two Daimler-Benz DB-603 engines with a take-off power of 1750hp. Two three-bladed propellers, during emergency ejection, the upper keel and rear propeller were fired. The rear motor unit with an extended shaft is 180 kg heavier than the front. The aircraft could fly on one engine, and when flying on the rear engine, the speed developed more. It is possible to install FuG-220 radar antennas on the leading edge of the wing, in connection with which the leading edge of the wing is made of wood.

This scheme was optimal when mounted behind a jet engine. The most important argument for the manufacture of such an aircraft was its long flight time compared to other jet aircraft. On January 18, 1945, Dornier received an order to develop such an aircraft - the Do-435. An alternative to the DB-603LA was the Jumo 213J. Tests of the first samples were to take place in May, but there was no time left for the implementation of this project.

After the war, the US Navy, although for a short time, used a tandem engine layout on two post-war carrier-based aircraft. Known are the Ryan Fr-1 "Firebull" and the Curtiss XF15 C-1, the latter being only marginally smaller than the Do-435. With engines of approximately equal power, American aircraft reached a maximum speed of about 100 km / h, yielding to the design value of the Dornier project.
