Abstract

The infrared radiation characteristics of aircraft engine plume are of great significance for aircraft detection and identification. At present, with the requirements of engine combustion chamber environment, some new coating materials came into being. This material will produce a large number of gaseous and solid ablation particles in the reaction process, so the emission and scattering of ablation particles must be considered in the calculation of plume infrared radiation transfer. Based on the refractive index data of ZrO2 particles given in the literature, the scattering phase function, scattering cross section, albedo and asymmetry factor of ZrO2 particles are calculated by T matrix. The scattering phase function of ablative particles at different wavelengths and the change of scattering characteristics of ablative particles with the passage of reaction time are analyzed. The results show that the scattering effect is obvious when the wavelength is short. With the increase of combustion time, the forward scattering of clusters increases sharply, and the scattering at all angles is more obvious. Therefore, it is necessary to accurately calculate the scattering characteristics of ablation particles in order to accurately calculate the radiation characteristics of aircraft plume in the future.
