abstract

The PW1120 engine is a turbojet derivative of the F100 turbofan engine that has accumulated more than 1.9 million flight hours in F-15 and F-16 fighters throughout the free world. Pratt & Whitney Aircraft (P&WA) initiated design and development of the PW1120 as a company sponsored military engine development program in 1980 and the program has progressed on schedule through more than 1,000 hours of development engine testing and Flight Clearance Testing. Performance goals and operational characteristics of the PW1120 engine at both sea level and altitude simulated flight conditions have been successfully demonstrated. This paper addresses the design characteristics of the PW1120 engine and its commonality with the F100 engine, and discusses those commonality benefits in terms of reliability, maintainability, safety, and logistics support. Development program plans, achievements, and applications for the PW1120 engine are also discussed. Flight Clearance of the PW1120 will be completed during the second half of 1984 with full qualification in late 1986. Production will start in early 1987. Initial application is in the Israel Air Force’s new indigenous fighter, the Lavi.
