patricksparks Posted February 16, 2018 Share Posted February 16, 2018 (edited) https://imgur.com/fslq2NZI am trying to find some information about the "Blast Shields" and the underlying pads that went with them. These panels were installed on B-25 C/D models with the upper turret in the rear waist of the fuselage, the shields were mounted in front and behind the turret to prevent damage to the aircraft's skin from the 50 caliber muzzle's blast. I would like to know how thick the plates were and if possible how they were mounted(visible fasters, etc ???). I have drawings that show the relitive size, I just haven't located any detailed information. Thanks for looking.

CANicoll Posted February 16, 2018 Share Posted February 16, 2018 (edited) I'm not a B-25 expert but I thought maybe by looking at some period pictures (not restored) it might help. See what you think: First picture the pads appear to be nearly flush, just slightly off-color from the fuselage. Here they seem SLIGHTLY raised over the fuselage, but nearly flush. Good luck!

p38johnny Posted February 17, 2018 Share Posted February 17, 2018 The blast shields were .019 stainless steel. The pad is a thin cloth material used as a barrier between the stainless and the aluminum skin. Even with primer, an additional barrier was used between dissimilar metals. I'm not entirely sure if rivets or screws were used. My first guess would be rivets. John Clements patricksparks 1 Link to comment Share on other sites More sharing options...
