Me.262 V9, W.Nr.130004: two questions...

[Richard T. Eger]

Dear Roger,

I was hoping you'd jump in on this, as you had studied the cockpit heating air system.

I spent about 20 minutes going back and forth through a myriad of photos, trying to find something on the Jumo 004 that would line up with that opening in the engine hatch. The problem was that only one photo showed a cylindrical device mounted near the top of the engine in the appropriate position for the tube extending from it to mate up with the opening. In all the other photos, this apparatus was missing, nor was there any identification of it in any of the Feb. 1944 JFM drawings in my possession.

What you suggest makes sense, but I'm just wondering why it failed to appear on other engines. That lack made me suspect it was part of the heating system, as this was not in use early on, although, admittedly, the thing certainly didn't look heating related. I can scan the photo for you for positive identification, if you like.

Regards,
Richard
