The Roar of Power

Connecticut Corsair has restored the R-4360 Wasp Major test cell that is available for Air / Trade Shows or a private corporate viewing.  We raise funds for our restoration project while displaying a fully functional engine complete with thirteen foot propeller.  The engine's run propels onlookers into the past when piston engines were king.  


The Connecticut Corsair R-4360 Test Cell in action at "Corsairs over Stratford", an event held in Stratford, CT in May 2010.  We use this display to fundraise for our F4U restoration project.  There is nothing like it when the big roar of the engine starts and its acceleration through the run draws the attention of everyone within earshot.  The test cell is available for airshows and trade shows throughout the northeast and arrangements may be made through this website.


Connecticut Corsair's R-4360 Test Cell

Connecticut Corsair volunteers restored the above Pratt & Whitney R-4360 Wasp Major test cell.  Between 1944 and 1955, PWA built 18,697 of the 4-row, 28-cylinder "corncob" radial engine.  Goodyear developed the Super Corsair with two variants, the F2G-1 and F2G-2 to take advantage of the larger engine as a specialized interceptor against kamikaze attacks.  As WWII was drawing to a close, development problems emerged that led to the abandonment of further work on the F2G series (only 10 were built) but several F2Gs went on to racing success after the war, winning the Thompson Trophy races in 1947 and 1949.


Firing order of the R-4360

The R-4360 was the last of the Pratt & Whitney Wasp family and the culmination of its maker's piston engine technology, but the war was over before it could power airplanes into combat. It did, however, power the last generation of large piston-engine aircraft before the turbojet and turboprop took over.  Almost every major airframe manufacturer of the time utilized the powerful engine, including Hughes Aviation with the infamous 8-engined Hughes H-4 Hercules ("Spruce Goose").
