ALLISON V-1710 COMPOUNDED ENGINE 480199

TEST results on the Allison V-1710 exhaust-turbine compounded reciprocating aircraft engine showed that compounding markedly increased power output and, at the same time, decreased specific fuel consumption.
One compounded engine, the Allison Model V-1710-E27, was built and tested. Compounding boosted power from 1200 to 1530 bhp at 30,000 ft and 3200 rpm.
Despite the promising test results on compounding, development was dropped. It was felt that the engineering manpower needed to develop a turbine capable of withstanding maximum exhaust-gas temperatures would be better employed on turboprop development.
