connected section and below it,is it a real project ?.

My dear Jemiba,


it seemed to be that,the Messerschmitt Bf.109Z was a real project,here is a more info

From the book; Die Deutsche Luftruestung 1933-1945 - Vol.3 - Henschel-Messerschmitt (Bernard&Graefe)


the Messerschmitt Bf.109Z was a real design,and there is two versions,Z-1 & Z-2.

Technically a DB project, but does anyone have information on the planned fitting of a Merlin engine to a 109 which was contemporary with the messerspitt.

Wow thanks a lot.
BV-155 had to cool powerful turbocharged engine by thin air of high altitude. Therefore a very huge radiator was needed.
This radiator position reduce wing root bending moment generated by wing lift force and bring some structural merit to reduce weight?
But moment of inertia around roll axis become large and reduce roll rate.

BV-155C-0/1 had a another shape. Intercooler was located behind the pilot.
Enormous front air intake is for radiator, oilcooler, turbocharger and intercooler.
BV-155C-1 was a BV-155 final version? But BV-155C-1 weight is heavy compared with BV-155B-1. Why?

Wiki says that...
"It was first proposed on 22 January 1943 at an RLM conference; at the time only three prototypes of the Me 262 had been completed. The Bf 109TL would be a backup if the Me 262 did not come to production or as a second fighter to operate alongside the Me 262.

In order to reduce development time, various components from previous aircraft were to be used. The fuselage was to come from the Bf 109H/BV 155B high-altitude fighter (with a new nose and tail section), the wing was from the Me 409 project and the tricycle undercarriage came from the Me 309. The powerplant would be the same Junkers Jumo 004B-1 turbojet (900 kgf thrust) or BMW 003A (800 kgf).

The basic armament was to be two 20 mm MG 151/20 cannons (with 120 rpg) and two MK 103 cannons mounted in the nose. An additional proposal was two 30 mm (1.18 in) MK 108 cannons to be installed in the wing roots. The pilot cockpit used in the prototypes was the same as utilized in the Bf 109E/G types.

The performance was estimated to be possibly better than the Me 262 due to the Bf 109TL's narrower fuselage, a product of the design for a high-speed high-altitude fighter. The Bf 109TL received intensive research. By March 1943, it was decided that many other modifications to components would be needed and the project was abandoned in order to concentrate on the Me 262 project."

Hi!
Me109/209/p.1091 stufe Ⅱ with DB628 engine.
DB628 had two stage supercharger. Low presssure(the first stage) supercharger was located behind the propeller and high pressure(the second stage) supercharger was located rear side of the engine. You can see a aftercooler rear bottom of the engine.
Also you can see the cover for piping between Low pressure supercharger and high pressure supercharger in these aircraft side view drawing.
Last drawing shows low pressure supercharger drive mechanism patent drawing.
Development of DB628 engine was cancelled.

It should be just noticed, the scale plans are marked as "reconstruction,  suppositious look".

Great and exciting drawing as usual!!! :D
Justo-san, how do you think about this very surprising and interesting DB624 engine?
I imagine that Daimler Benz must be appealed this engine for Messerschmitt high altitude fighter or high altitude recon/bomber.
This engine had mechanical drive(Valkan coupling drive?) superchargers at both side of the engine as the first and the second stage supercharger, and also had turbo charger as the third stage supercharger at the bottom of the engine.
Intercoolers were located exit of the first stage supercharger and exit of the second stage supercharger.
Unbelievable layout. :o B)
