Abstract

Particulate-phase  exhaust  properties from two different types of ground-based  jet   aircraftengines —high-thrust and turboshaft—were studied with  real - time  instruments on a portable pallet and additional  time -integrated sampling devices. The  real - time  instruments successfully characterized rapidly changing particulate mass, light absorption, and polycyclic aromatic hydrocarbon (PAH) content. The integrated  measurements  included particulate-size distributions, PAH, and carbon concentrations for an entire test run (i.e., “run-integrated”  measurements ). In all cases, the particle-size distributions showed single modes peaking at 20–40nm diameter.  Measurements of exhaust  from high-thrust F404  engines  showed relatively low-light absorption compared with  exhaust  from a turboshaft  engine . Particulate-phase PAH  measurements  generally varied in phase with both net particulate mass and with light-absorbing particulate concentrations. Unexplained response behavior sometimes occurred with the  real - time  PAH analyzer, although on average the  real - time  and integrated PAH methods agreed within the same order of magnitude found in earlier investigations.
