The Arado E.583 was a project draft from 1945 for a jet-powered night fighter aircraft from the German manufacturer Arado Flugzeugwerke GmbH .

history

The design of the E.583 goes back to the E.581 , an earlier project by Arado, in which design variants for a single-jet, tailless (without horizontal stabilizer) night fighter were also examined. The starting point for the E.581 was again the studies in connection with the E.555 project for a multi-jet long-range bomber. The Heinkel HeS 011 jet engine of the E.581, which is integrated into the fuselage , however, due to the long inlet and the large fuselage surface, only expected insufficient performance in the high-speed range.

Arado then created two new project drafts in accordance with the guidelines issued in January 1945 for the optimum solution for a night fighter. The studies Ar I and Ar II - also referred to as project I and II - were presented at the same time under the overall designation E.583.

The Ar I was based on the draft E.581-5, but had significantly larger dimensions. The reviewers complained on 20./21. March 1945 again the resistance-generating engine intakes and large surfaces. Arado then improved the design so that a third crew member and a larger amount of fuel could be accommodated. A third variant received smaller and more strongly swept wings. It is said to have served as a model for the American Vought F7U-3 Cutlass . However, the head of Vought's aerodynamic research department, William C. Schoolfield, denied that there was any orientation towards German research results.

The Ar II was an easier to implement alternative for a night and bad weather chaser. The design had swept wings and was based heavily on the Arado Ar 234 and the TEW 16 / 43-23 study. The maximum speed was calculated to be 775 km / h and thus lower than that of the Ar I.

construction

The Ar I was designed as a tailless aircraft in which the ailerons also served as a horizontal stabilizer. The two rudders were each placed on top of the wings.
