This air passes through the intercooler where it is cooled before being directed back to the engine and the carburetors for each of the 18 cylinders. The air entering the turbocharger is compressed and, in the process, is heated.There is a lot of intake ductwork needed to get ambient air routed from the main air duct intake immediately under the engine to the turbocharger and intercooler and then back to the carburetors on the engine. The R-2800 engine is turbocharged, with the turbocharger, intercooler, and related subsystems all located behind the pilot. The basic engine installation can be seen in the following illustration of a P-47 without its engine cowling: Engine: One Pratt & Whitney R-2800 radial rated at 2,430 hp.A representative P-47D is shown in the following photo.īasic specifications for a P-47D are listed below (Source: National Museum of the USAF): That tactical flexibility was enabled by its turbocharged Pratt & Whitney Double Wasp R-2800, two-row, 18-cylinder radial engine.
The P-47 Thunderbolt, built by Republic Aviation, was a powerful WW II fighter that was capable of operating effectively at high-altitude as a long-range bomber escort or at low altitude as a fighter bomber.
