Question: when BF-109 G6 ASM was used? already in Normandy?

[kraut1]

Hi,

I am interested in flying the ASM variant.

Was the ASM used in the Normandy?

Or if not when later?

Thanks in advance

MW50 started being introduced in May 1944, so there is a probability at least some of the G-6/AS planes at Normandy would have had it.

If you read Knoke's diary for around April - May 1944 he already speaks of 'large superchargers' and 'methanol boost' being used in the aircraft of his unit.

They were also in Normandy, so, definietely yes, the ASM was used in Normady (though designation of the engine aircradt changed a lot in this time).

 

RLM documents from May 1944 suggest the first variants were modifications to the G-6s with GM 1 delivered by ERLA Antwerp and ERLA Leipzig with GM - 1 tanks, which was to be modified to AS engines and MW 50, since these already had everything in place and required simple modifications. At a later stage (July) all  109G were to (and did( have a 'simplified' MW 50 system (simplified as it used compressor pressure instead of separate air bottles to pressurize the MW system). This latter is basically the G-14.

 

Recce G-8s with AS and (or?) MW are also document to have been delivered to Luftflotte 3 in July.

.... to be more specific, from a set of Luftwaffe records on a conference held on 18-19 May 1944, various engineers discussing GM 1 and MW 50 system, conversions, frontline experience, supply etc.

 

Two ways of using MW 50 are described, first, conversion of already built in GM 1 tanks (in G-5/U2, G-6/U2 for example) to MW 50 operation, and then switching over in series production to simplified, dedicated MW 50 system. 

 

In his summary on frontline experience with GM 1 and MW 50, Chief Engineer Thomas mentions that MW 50 has been successfully employed by BF 109G fronline units to increase engine output from sea level to the full throttle height of the engines. It also serves to increase internal cooling of the engine.

 

 

Conversion of existing GM-1 system to MW 50

 

I. Conversion of existing GM 1 systems

A. Bf 109G-6 delivered by Erla-Leipzig with GM - 1 systems are to be retrofitted with AS engines and to MW 50

by Erfurt Reperaturwerk and

by Blohm und Voss Hamburg

B. Bf 109G-6 delivered by Erla-Antwerpen are converted to AS engines and MW 50 [by Erla-Antwerpen itself]

Number of aircraft to be converted from GM -1 system to MW 50: cc. 300

C. Aircraft already deployed at combat units that equipped with GM 1 are to be converted to MW 50 with the DB 605A.

 

II. Changeover to simplified MW 50 system

(ie... pressure to MW tank is provided via tapping the supercharger instead of using the pressurized bottles of the legacy GM 1 system)

A. Retrofit via factories, with installation of DB 605AS.

50 aircraft in May,

80 Aircraft in June 1944

B. Retrofit at the combat units,

150 aircraft in June

C. Serial production of Bf 109G-6 with simplified MW 50:

225 aircraft in June,

all aircraft from July

I'm resurrecting this thread, which has been dead for almost a year, because I found nice articles on this topic in Edurard's Modellbauer Magazin:

Happy reading, although still confused after overflown it. 😅

Yep, good articles. Breaking that down to what we actually have in the game is:

 

a) Bf 109 G6/AS with AS engine

b) Bf 109 G14/AS with ASM engine and MW50

Possibly, if the article would be considered comprehensive and exhaustive. Obviously it´s not, as you can clearly observe ingame. 😉

These Eduard's articles are impressive! Thank you for the discover!

I start to read some article, especially the ones dedicated to pilot's combat histories, I'm truly enjoying them!
