A Status Report on the Energy Efficient Engine Project

The Energy Efficient Engine (E³) Project is directed at providing, by 1984; the advanced technologies which could be used for a new generation of fuel conservative turbofan engines. The project is conducted by NASA through contracts with the General Electric Company and Pratt & Whitney Aircraft. This paper summarizes the scope of the entire project and the current status of these efforts. Included is a description of the preliminary designs of the fully developed engines, the potential benefits of these advanced engines, and highlights of some of the component technology efforts conducted to date.
