Abstract:

The problem of mass emisssions from aircraft gas turbine engines is briefly reviewed and the aspects of this problem which are unique to military aircraft operation are discussed. Pollutant measurement technology and the existing data base are summarized and candidate control techniques are identified. Proposed Environmental Protection Agency regulations for aircraft engine emissions are examined in terms of their impact on and application to military engines. It is concluded that the special considerations, both performance and otherwise, which must be afforded to military aircraft prohibit direct application of the EPA regulations. The report concerns Air Force emission limitation goals established in light of these efforts. Maximum allowable idle combustion inefficiency, oxide of nitrogen emission 1bm1000 lbm fuel, and smoke number are specified. The rationale behind using these parameters, and the means by which the numerical goals were derived are discussed. Author
