Flying Rooster Posted March 12, 2016 Share #1 Posted March 12, 2016 Need some information about a Pratt & Whitney engine. -The P & W R 2800-21 was used on what aircraft? -It's SerN° is 42-126159. Was this engine produced during the war? -What does the abbreviation "WRAD" means? -Is "4-23-45" a production date? -For what stands "TT763" on the engine?

M1Garandy Posted March 12, 2016 Share #2 Posted March 12, 2016 The R-2800-21 was used on several models of P47's according to Graham Whites book on the R-2800. I can't find a good picture of a -21 dataplate so is there any chance you can post a picture of the data plates on the engine in question? WRAD could be an overhaul facility, 4-23-45 could be a overhaul date and TT763 could indicate that the engine had 763 hours total time when it was overhauled. If you have access to the engine logs, that might help too. Link to comment Share on other sites More sharing options...
Cobrahistorian Posted March 13, 2016 Share #3 Posted March 13, 2016 Yep, the -21 was used on razorback P-47Ds and I would think that the 4-23-45 date was an overhaul date like M1Garandy said. Link to comment Share on other sites More sharing options...

northcoastaero Posted March 14, 2016 Share #5 Posted March 14, 2016 WRAD could stand for Warner Robins Air Depot in Georgia? Hope this helps. Link to comment Share on other sites More sharing options...

bobatl Posted April 8, 2016 Share #7 Posted April 8, 2016 Depots during WWII would normally stamp their ID, engine serial no., total time, and overhaul date on nose case or front section of main case. Same info could also be stenciled on nose case. Cylinders would have total time pencil etched on skirt or would be marked "NEW" if a new cylinder was installed. WRAD became WRAMA (Air Material Activity) in the 1950's and is now WR-ALC (Air Logistics Center). Link to comment Share on other sites More sharing options...
