abstract

Whether the intended application of a gas turbine engine is aero-propulsion or power production, the engine exhaust gas emissions must comply with all applicable air quality regulations. For an aircraft gas turbine engine, the current range of certifiable operating conditions includes the landing and takeoff cycle. For a stationary, power-producing engine the range of operating conditions is narrow, but there is increasing interest in measurements of speciated hydrocarbons and other species that pose health and environmental hazards. Existing emission measurement methodologies are time consuming and expensive. An engine emissions survey was performed on a JT-12 engine at Middle Tennessee State University using a new integrated rapid sampling, measurement, and analysis system. Improved methodologies should be considered for turbine engine emissions certification.
