SAMPLE I - Studying, sAmpling and Measuring of aircraft ParticuLate Emissions I


The objective of this study was to perform a preliminary assessment of methods for measuring particle mass concentration and composition, particle number concentration and particle size distribution. These methods were tested and evaluated under real conditions with respect to their applicability for aircraft engine exhaust emissions certification applications.

The work was performed using the Combustor - Hot End Simulator test rig which was initially developed during the European FP5 programme PARTEMIS. This test rig served as a stable aircraft engine simulator providing particles of physical-chemical properties similar to real aircraft engines. The operating conditions were designed such that the physico-chemical properties of the generated combustion aerosol covered the widest possible range from low smoke emissions associated with high organic matter emissions to high smoke emissions associated with low organic matter emissions.
