Dornier Do 535

The Dornier Do 435 was a planned attack aircraft of Dornier works. Good evidence of the manufacturer are the project names. About the official names, especially the classification in the RLM - type list, there are contradictory statements. Therefore, the various projects and development directions are summarized in this article.

History

The already in its basic design very powerful fighter aircraft Dornier Do 335 was examined for more ways to increase his performance. Basic design of the Do 335 was their drafts Thu P 231/1 and Th P 231/2 then also led to the production version of the Do 335 after the P59 Thu Thu P 231. At the beginning of 1943 examined Dornier Do in design P 231/3 but also the use of a jet engine instead of the rear piston engine (note: First Flight Do 335V1 on 26 October 1943). The front engine was a Daimler- Benz DB 603 remain.

In May 1943, the successor Th P 232 was built with similar design as jet engine, the Jumo 004 was provided. The mixing drive promised a utilization of the advantages of both types of drives - achieving great routes when flying with piston engine, high speed switching of the jet engine, shorter take-off distance by high initial performance of the piston engine, weight reduction through the lighter jet engine. It is armed with two MG initially been configured 151/20 on the front engine, later was added a MK -103 motor cannon. As a bomb load 500 kg were provided up to a maximum of 1000 kg. The air inlet for the turbojet engine with an S-shaped inlet should be on top of the fuselage and be closed during the Einmotorenflugs by a resilient flap.

In autumn 1943 the Air Ministry a successor model named Do 435 was proposed.

While maintaining the structure 435 of the fuselage should be redesigned for the Do. He should be stretched and get the cab for better all-round visibility, a teardrop-shaped hood. The characteristic high fuselage of the Do 335 was accounted for it. When driving two Jumo 222 should be used with total over 4000 hp. Structurally, the Do 435 was in an advanced stage. As a model aircraft in the conversion of the Do 335 V4 served. In the fall of 1944, the development was discontinued by order of the RLM, since the power of the Do 335 was classified as adequate.

In summer 1944, the RLM called for a rapid reconnaissance with a range of over 7500 km. Heinkel suggested by his experience with the He 111Z a similar solution with two combined Do 335 before. Started as a draft Hey P 1075, the project was officially referred to as the Dornier Do 635. Also Junkers dealt with a similar solution, which was run as a Junkers Ju 635.

In the night fighter development is still under investigation as a do P 256 pure jet propulsion. Two Heinkel 011 HeS should like the Messerschmitt Me 262 to be hung under the wings and the characteristic fin soft a conventional rudder. It is armed with four MK 108 were planned, an additional reverse armament was thinking.

According to some sources, it should have been a draft Thu P 254. This was renamed the Do 535 and in October 1944 after the handover to the Heinkel works in Heinkel He 535

The Do 535 said to have been designed as all-weather fighter and fast reconnaissance. The basic design came from the Do 335 B with a second man under a small glass dome in the rear fuselage section. The rear engine DB 603 A-2 should be replaced by a Heinkel HeS -011 jet engine. Thus the concept of the Do 535 still felt very much like the Do 335 B. In the role as a night fighter should additional tanks are attached to the undersides of the wings, a FuG 218 radar should be mounted on the wings, and the maximum speed should 822 km / h. The armament consisted here of a motorlaffetierten heavy 50 -mm cannon MK 112, two Mg 151/20 mm in the wings approaches, and two Mk 108 as " Weird Music " in the fuselage. According to other sources, the armament of two Mg 151/20 on the motor, a motor cannon Mk 108 and Mk 108 two should be as inclined armament in the center hull. The speed is given here 822 km / h in 7.5 km altitude and 865 km / h in 11.2 km altitude.
