Pratt & Whitney R-1830 Twin Wasp two-row cylinder engine, USA 1934
High point of the piston engine: powering passenger aircraft and bombers
The Twin Wasp ranks amongst the most significant aero piston engines in aviation history. In excess of 20,000 of them were incorporated into the DC-3 and C-47 Dakota and more than 76,000 into B-24 Liberator bombers.
Featuring a compact two-row, 14-cylinder, air-cooled radial design, the engine delivered twice the power of the single-row version without adding significantly to the weight or air resistance. The front surface of the cylinder increased, but not that of the crankcase.
Increasingly powerful two-row cylinder engines continued to provide the means of propulsion for most long-haul passenger aircraft cylinder after the Second World War. Regardless of their success, however, these robust piston engines were quickly eclipsed by the appearance of the jet engine in the 1960s.
