WW2 R-1830 Twin Wasp (Half Cylinders) (1 Bank)

The R-1830 Twin Wasp is an American air-cooled radial aircraft engine. It displaces 1,830 cu in (30.0 L) and its bore and stroke are both 5.5 in (140 mm). The design traces its history to 1929 experiments at Pratt & Whitney on twin-row designs. Production began in 1932 and it was widely used during the 1930s. It was selected as the power plant for both the four-engine Consolidated B-24 Liberator heavy bomber and the twin-engine Douglas DC-3 transport, two of the most-produced aircraft. The production run of 173,618 R-1830 examples makes it the most-produced aviation engine in history.   Commonly Found in Aircraft Such As: Bloch MB.176 Boeing XB-15 Budd RB Conestoga Burnelli CBY-3 CAC Boomerang – Australian "emergency fighter" CAC Woomera Consolidated B-24 Liberator Consolidated PBY Catalina Consolidated PB2Y Coronado Consolidated PB4Y Privateer Curtiss P-36 Hawk DAP Beaufort – Australian-built variants of Bristol Beaufort Douglas C-47 Skytrain Douglas DC-3 Douglas DB-7 – early var
