Information × Registration Number 0125U004060, R & D request Title Upgrade of the methodology for calculating the IR visibility of gas turbine engine Head Zinoviia F. Tsybrii, Доктор фізико-математичних наук Registration Date 05-12-2025 Organization V. Lashkaryov Institute of Semiconductor Physics of National Academy of Sciences of Ukraine popup.description1 Engine hot parts (the turbine and the nozzle) along with the exhaust gases are the most important sources of infrared radiation from the aircraft. The goal of this work is an upgrade of existing software, which should allow modeling of infrared radiation intensity produced by: - exhaust gases plume after the engine nozzle - flat nozzles (with rectangular or trapezoidal cross-section instead of circular one) and side nozzles (for helicopters) - particulate matter (soot) Also software upgrade includes development of the functionality for the estimations of the range of relative changes of detection distances due to the changes in engine parameters. popup.nrat_date 2025-12-05 Close
