It was the "Zwiling" (twin) conversion of two Me 209V5
with two DB 603G engines.Timeframe 1943/44.
Messerschmitt Me 409
From Wikipedia, the free encyclopedia
Status: Unrealised project
The Messerschmitt Me 409 was an abandoned design for a fighter aircraft. It was intended to be two Messerschmitt Me 209-II fuselages joined by a common wing section like the Messerschmitt Me 109z (2 Me 109's) and the Messerschmitt Me 609 (2 Messerschmitt Me 309's). Most of the aircraft parts would come from the mainly from the Me 209-II. The engines would have consisted of Daimler Benz Db 603's as on the Me 209-II. Arnament would have been like the Me 109Z and Me 609 (4 MK 108 30mm cannon's and 1 MK 103 30mm cannon). The project was canceled along with the counterpart Me 209-II.
Stargazer2006 said:Nice scan, Justo... Thanks ! But why did you label the image "P.1116 001"?? It is a source of confusion as it could give the impression this was also designated P.1116 (when that designation was in fact allocated to a jet project).
carsinamerica said:From Hitchcock (Messerschmitt O-Nine Gallery), p. 101:
"The RLM advised Messerschmitt to expedite development of a high altitude fighter by incorporating Me 209H systems directly into the Bf 109H program (see p. 92). Messerschmitt complied, but continued construction of the Me 209H V1, albeit on a low priority basis. Accordingly, early in 1943 a design was advanced based on the Me P.1091a resulting in the Me 209H. Although it was not fitted to the Me 209H V1, the DB 627B [I think this should be DB628 based on other references Hitchcock makes] was selected. Delays protracted its completion until June 1944, and by this time the Me 209 and the DB 627 programs had been cancelled. Therefore, the Me 209H V1 was completed with a DB 603G (similar to the DB 627 but lacking after-cooler and two-stage mechanical supercharger)."
So, there was the Me 209 V1 through V4 (the record-breaker), with the V4 being the proposed fighter.
Then followed the Me 309
Then the revised Me 209, usually called the Me 209-II.
Then the RLM wanted a high-altitude variant of the 209-II. It sounds, though, that the 209H was really a continuation of the stretched Bf 109 program (P.1091a), and only used some systems architecture from the 209A.
Jemiba said:What I've found out, up to the Me 209 V 4 the design was directly based on the record aircraft, with
test flight proving to be disappointing, with no chance of fitting internal weapons to wing, as it was too
thin and was still needed for radiators.
From the V 5 onwards, it was actually a completely new design, submitted as contender to the Ta 152,
which should use as many Bf 109 components, as possible to ease production.
