About the Photos

Our holdings include hundreds of glass and film negatives/transparencies that we've scanned ourselves; in addition, many other photos on this site were extracted from reference images (high-resolution tiffs) in the Library of Congress research archive. (To query the database click here.) They are adjusted, restored and reworked by your webmaster in accordance with his aesthetic sensibilities before being downsized and turned into the jpegs you see here. All of these images (including "derivative works") are protected by copyright laws of the United States and other jurisdictions and may not be sold, reproduced or otherwise used for commercial purposes without permission.

Angel of History: 1942

Angel of History: 1942

B-25 bomber cowl assembly, North American Aviation, Kansas City, Kansas. October 1942. View full size. 4x5 Kodachrome transparency by Alfred Palmer.

 

Shock Mounts

Those yellow things are Dynafocal mounts, where the powerplant attaches to the engine mount ring, which is attached to the airframe structure. They dampen vibrations from the running engine and keep them from transferring to the airframe. The cowl flaps are on separate ring which goes on after the engine and mount are joined. I do not know if the 25 had electric or hydraulic actuators. There is also a metal/asbestos ring (fire seal) which goes around the gap where the engine accessory case goes thru the hole where the worker's head is.

Cowling

I believe the yellow painted parts on the cowling are actuators that open the small cowling doors around the engine for cooling on the ground during runups and taxing, if anyone knows about this, I'd like to know more about it.
