The Pratt and Whitney Double Wasp was a common engine used in World War Two aircraft. It has 18 cylinders in a double row configuration, or two rows of cylinders. Each row has nine cylinders. The engine has a displacement of 2,800 inches and produces 2,000 horsepower. Some aircraft that used this engine include the F6F Hellcat and the P-47 Thunderbolt. This engine was quite heavy, weighing in at 2,350 pounds, about the weight of a small car.
Technopower Engines
Small-scale engines are popular with model airplane enthusiasts. Technopower engines are radial engines displacing anywhere from 1.35 to 4 cubic inches. They are four-stroke overhead valve designs, and serve as replicas of full-scale engines in radio-controlled models.
Vedeneyev M14
The Vedeneyev M14 is a Russian engine built by the Vedeneyev group. Production started in the 1950s and ended in the mid 1980s. After years of refinements and upgrades to the M14 series, the final engine produced 360 horsepower. It is an efficient engine, having a horsepower-to-weight ratio of 1-to-1, or one horsepower per pound. Being versatile, this engine is used extensively in aircraft and in Siberian oil fields to drive equipment. In 2010, this engine is very much in demand. In 2007, Ramon Alonso won the World Aerobatic Championships with a plane powered by a Vedeneyev M14.
