N1 - Particulate-phase exhaust properties from two different types of ground-based jet aircraft engines-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.

N2 - 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.
