The ABC
Wasp is an experimental seven cylinder radial engine of 170 horsepower,
designed by the noted British engineer Granville Bradshaw. At a weight of
290 lbs., it had one of the most advanced power-to-weight ratios of the
day -- 1.7 lbs. per horsepower. This WWI era engine is noteworthy because
it was the first in which the cylinders were coated with copper in an
attempt to dissipate heat. The ABC Wasp never evolved beyond the
experimental stage, but it was the predecessor of the unsuccessful
production "Dragonfly" engine. |
