The Reduction of Smoke Emissions from Allison T56 Engines
Abstract
Aeronautical Research Laboratory (ARL) has been working to reduce smoke emissions from the Allison T56 engines used in the Lockheed P-3C Orion aircraft operated by the Royal Australian Air Force (RAAF). The work consisted of a literature survey, design and manufacture of a water tunnel model, water tunnel testing of various modifications to improve the fluid dynamics of the combustion system, testing the modifications in a single liner combustion test rig, smoke emission comparative tests in ground run engine trials, performance tests in a calibrated test cell and flight trials of a modified engine. The modification that was developed in this program was found to significantly reduce smoke emissions and give substantial improvements in the specific fuel consumption of the engine. In addition, there were indications, in line with theoretical predictions, that the modification would extend the life of the hot end components of the engine. Keywords: Smoke abatement, Combustion products, Exhaust emissions, Allison engines, P-3C Aircraft, Australia.
