Sikorsky Product History

The engine was to weigh 400 pounds and produce 800 HP, a two-to-one improvement over the legacy, reciprocating Wright R-1820 engine powering the HSS-1. The result exceeded expectations. The resulting engine weighed 324 pounds and generated more than 1,000 HP in a 10 cubic-foot package compared with the legacy piston engine of 62 cubic-feet. ................
