Pratt & Whitney J52
From Wikipedia, the free encyclopedia
The Pratt & Whitney J52 is an axial-flow turbojet engine built for the US Navy, in the 9,000lbf class. It powered the A-4 Skyhawk, A-6 Intruder and powers the EA-6 Prowler. Within Pratt & Whitney it had the designation JT8A, and provided the basis for the Pratt & Whitney JT8D, the most popular civilian low-bypass turbofan engine.
The J52 employs a split 12-stage axial compressor consisting of a five-stage low pressure unit and a seven-stage high pressure unit. Behind the compressor is a nine-unit can-annular combustion chamber and a two-stage split turbine.
