Gas Turbine Engine Smoke Measurement Cross Correlation
Abstract
An extensive air sampling program was undertaken to measure the particulate emissions from various gas turbine (jet) engines used in military aircraft. This joint Navy, Air Force project was directed and accomplished by the Navy Aircraft Environmental Support Office (AESO) at NAVAIREWORKFAC North Island. The project was accomplished per MIPR S-80-21. The objectives of the study were: First, measure smoke mass emissions at the engine exhaust plane and correlate the results with measured smoke numbers. Second, compare the smoke mass emission measured simultaneously by two different direct mass measurement procedures. A third objective was to measure the particle size distribution of the jet engine exhaust aerosol. Descriptions of the sampling methods used in this project are given in the next section. The aim of the project was to correlate the results obtained using several different particulate emission sampling methods on various military jet engines and determine if other indirect measurement methods can be used to adequately determine particulate emissions. A variety of engine types were tested including: J79-GE-8C/D, J79-GE-10B, F404-GE- 400, TF30-P-414, and J52-P-6B engines. The bulk of the testing and analysis was centered around three engine types: J79-GE-8C/D, J79-GE-10B, and F404-GE-400, due to their availability and widespread use by the Navy.
