Abstract |
This report is a brief summary of the status of the aircraft gas turbine technology assessment program. It is a compendium of the information and technical data received from all organizations, government and industrial, involved in efforts to reduce aircraft engine exhaust emissions. The technical data have been reduced and presented in the format that the EPA intends to use in making its assessment of the growth of low emissions technology in aircraft gas turbines. This actual assessment is, therefore, only a prelude to the assessment topic in that report. The information contained herein and the thrust of the assessment are directed towards compliance with the EPA 1979 standards for newly manufactured engines. Consideration of compliance with the 1981 standards for newly certified engines will be given in later reports as the technology advances. |
