EXHAUST smoke emission from high pressure ratio aero gas turbine engines currently in service has been reduced largely by attention to fuel air mixing in the combustion chamber. It is demonstrated that aerated fuel sprays provide the additional control required as pressure ratios increase still further on new engines. The proportion of produced carbon which can be burned in high temperature regions of the chamber will increase as both combustion maximum and turbine entry temperatures increase. To provide a quantitative assessment of the degree of visual nuisance of smoke trails, prediction methods are being developed with the aid of data from research programmes.
