Dornier Do-335 "Pfeil"

By Heinz J.Nowarra, Edward T. Maloney

Photo Description

The Göppingen GÖ 9 successfully proved that this unique pusher-propeller design could be flown safely and without difficulty.

The first flight trials with the tail-propeller installation were carried on with the Göppingen Gö 9.

Dornier DO 335 V-3 (CP + ZH). This rare view clearly shows the changed nose design from the original Do 335 V-1. The oil cooler was included in the front ring cowl. A large airplane by any standard, the Do 335 weighs more than 18,000 lbs. with standard armament.

Dornier Do 335 V-3 at the factory. This prototype did not carry full radio equipment or armament. The Do 335 design qualified as an all purpose aircraft—day fighter, night fighter, recon aircraft and fighter bomber.

Full front view of Dornier Do 335 V-3 gives an impression that this design is a single engine fighter. Note the wide tract tri-cycle landing gear. Its amazing performance surprised many Luftwaffe pilots in spite of the oddity of its design.

Unusual view of Dornier Do 335 clearly shows the marked recognition feature of the cruciform tail. Rear engine was amidship in the fuselage driving a pusher propeller via an extension shaft.

Dornier Do 335 V-l (CP+ UA), prototype of the series, made its first flight in the autumn of 1943. This flight view shows the V-1's distinguishing oil cooler under the nose.

Nine months after receiving the initial order from the German Air Ministry, the Do 335 V-1 was ready for its first maiden flight. Note large circular landing gear doors and oil cooler under the nose.

Outline shape of the Do 335 V-1 was almost identical with the final DO 335 A-1 design except for the oil cooler installation. Operating on one engine, it could move along at 350 m.p.h. and with both engines turning it could do 425 m.p.h. One interesting fact is that the greatest single engine speed was attained with the pusher engine turning and the front propeller feathered.

DO 335 V-3, having just completed a successful test flight at the factory, is being prepared to be towed to the hangar for maintenance. Note special tow-bar dolly by nose wheel. The DO 335 V-3 was unarmed as were the V-1 and V-2 prototypes.
