This engine powered the last generation of piston engine transports, including the Douglas DC-7 and Lockheed Super Constellation. It represents the end of engine-development that began with the famous Wright Whirlwind, and included an entire family of military and commercial piston power plants. The somewhat unique feature of this engine was a turbo compound device, consisting of an exhaust-driven turbine geared to the crankshaft, generating 20 percent additional take-off power without increasing fuel consumption.
