- Abstract
- Infrared (IR) signals from the hot exhaust gases of aircraft engines have a significant impact on the survivability of aircraft. Several methods were developed to reduce IR signatures to avoid tracking by IR signatures generated in the exhaust, or decoy flares are used to deceive IR seekers. Research into injecting water particles to lower the exhaust gas temperature or injecting carbon particles to shield the plume has also been previously conducted. In this study, we propose a method for injecting solid/liquid mixed particles that lower the exhaust gas temperature and block IR signal propagation generated in the exhaust gas. The multiphase flow in aircraft nozzles by solid/liquid mixed particle injection was analyzed using the CFD code for the total flow rate of particles corresponding to 5%, 10%, and 20% of the exhaust gas flow rate. After analyzing the characteristics of the mixed particles interacting with the exhaust plume, the optimal flow rate of water and carbon particles with a small thrust penalty was obtained.
