| P&W PT1 Free-piston gas generator intended for use with P&W's first gas turbine. |
P&W PT1 A turboprop, the PT1 never flew. |
P&W PT1 The PT1 was P&W's last liquid-cooled engine. |
P&W R-1535 | P&W R-2060 Liquid-cooled 20-cylinder built for US Army Air Coprs in the early 1930s. |
P&W R-2060 The "Yellow Jacket" suffered from fuel mixture distribution problems. |
P&W R-2060 P&W's first liquid-cooled engine never flew. |
P&W R-2180 "Twin Hornet" of 1938 was upstaged by the R-2800. |
P&W R-2180E The R-2180E, circa 1949, shared parts with the R-4360. |

| P&W R-2270 First run in 1930, P&W's first two-row radial. |
P&W R-2270 The R-2270 was built from Wasp and Hornet parts. |
P&W R-2270 | P&W R-2270 | P&W R-2270 | P&W R-2270 | P&W R-2800 This B Model has an early torque nose case. |
P&W R-2800 D Model cylinder with reversed cooling air flow was only used on Northrop XP-56. |

P&W R-4360 Cooling fan for B-36. |
P&W R-4360 VDT Curtiss-Wright R-3350 used power recovery turbines geared to the crankshaft. P&W used exhaust energy for supercharging and jet thrust in the Variable Discharge Turbine. |
P&W R-4360 VDT | P&W R-4360 VDT With intercoolers, turbines, compressors and ducting, the VDT was as large as the engine. |
P&W XH-3730 | P&W XH-3730 | P&W XH-2600 Also called X-1800, this 24-cylinder liquid-cooled engine was built for the US Army Air Corps. |
P&W XH-2600 | P&W XH-3730 24-cylinder liquid-cooled XH-3730 was intended for the US Navy. |
