Paper Abstract

The Scanning Infrared Gas Imaging System of High Resolution (SIGIS-HR) was used to perform non-intrusive measurements of a Boeing 737 and a diesel powered burned (used as a hot gas producer). During the measurements it was observed that the selection of the optimal measurement positions into the plume, visualised by an infrared image from a real-time infrared camera in which the emission intensity of different field of view (FOV) positions into the plume are plotted in false colours, is possible very precisely. This enhanced considerably the probability of detection of infrared radiation emitted by a hot gas plume (e. g. from an in-service aircraft at the ground) for the objective to determine composition and temperature of the exhausts. Using this improved localization of the optimum measurement position into the hot exhaust plume the temperature and the concentrations of CO and NO were calculated. Additionally, the spatial distribution of gas temperature and concentrations of CO, CO2 and NO into the exhaust plume were determined.
