Natter, below is a link to a PDF verson of the G7a drawings to download. You will be able to zoom in/out on the drawings.http://www.mediafire.com/view/?3ug1zgdoqqxvfow
Quote from: NZSnowman on 01 Jan , 2013, 18:59I imagine for the non-Lut G7e torpedoes that they used the same tail section as for Lut G7e torpedoes, and the only different being that the safety locking pin was kept in place for the non-Lut G7e torpedoes?No. Different vertical fins (see attached photos of the "normal G7e fins). The expandable rudder is a sort of "sleeve" fitting outside the fixed rudder. The fixed rudder is also different, as it has the guiding slots for the pins in the expandable part.

If you refer to the pin on the aft part of the rudder, this is a guiding pin for the expandable rudder (fits in a slot in the fixed rudder - same with the pin fastened to the pneumatic sylinder).Quote from: NZSnowman on 01 Jan , 2013, 18:59Looking at that photo's, was there a small piston that extend to keep the fins extended outward, is this correct?Yes, this is a pneumatic cylinder controlled by the gyroscope, extending the rudder when the torpedo turns, to avoid the torpedo pitching and waving off course, due to the depthrudders becoming side-rudders vice versa).

Looking through photos, I just now realized that the TXI torpedo preserved in UK is equipped with the expandable rudders. No photos of the TV torpedoes (wartime + U-505 collection) shows the same. Wether the TXI had a Lut-program as backup for the acoustic control I don't know (doesn't seem likely). I guess it's possible they decided to incorporate this as a measure to make the TXI more "agile" than the TV though, or perhaps the british simply used a standard aft-section in the restoration of the TXI.

The external differences of interest to you, is the use of the "h
Hi, I was reading one of the best christmas presents ever received and found some exotic torpedo warheads that u might find interesting.
Must pictures of the T5 and T11 show them without the nose cap. Were these torpedoes fired with or without the nose cap?
What was the conclusion with the late war Type VIIC
