Definition Of

A standard system (equipment and procedures) for measuring smoke emitted by aircraft turbine engines has been developed. It has been adopted by several Federal Government agencies. In this paper, the system is explained and its accuracy defined. An experimentally determined relationship between the system’s parameters and true smoke density (weight of solids per unit volume) is presented and theoretically examined. The definition of smoke plume visibility in terms of the system’s parameters is also developed. This work led to the conclusion that aircraft turbine engine exhaust smoke is composed of two groups of particles: the very small, which are primarily responsible for visible obscuration, and larger particles, which may constitute as much as half of the total by weight, but do not appreciably contribute to plume visibility.

Exhaust Gas Emissions

Aircraft engine technology has gained major advances in the past 40–50 years, steadily bringing significant gains in the reduction of exhaust emissions at the source. However, with the projected increase in air traffic, the cumulative amount of aircraft emissions will still increase. This maintains the need for further progress in developing analytical methods to predict the amount and composition of exhaust gases from aircraft engines to better assess the alternatives for reducing emissions and better inform decision-makers, manufacturers and operators. The Research Project “Aero-Gasturbine Emission Reduction and Simulation Technology”, started at the Delft University of Technology in collaboration with the Dutch National Aerospace Laboratory (NLR) and the Netherlands Ministry of Traffic, is aimed to contribute to the efforts to solve the problem. With the limitations, complexity and costs of emission measurements at operational conditions, the ability to predict engine exhaust emissions by means of analytical tools becomes more urgent for minimizing aircraft engine exhaust gas emissions. This paper presents a philosophy and approach to develop such tools.
