Abstract:

The anti-infrared radiation method of particle medium is one of the important means of aircraft tail flame stealth.In order to promote the research and development of granular materials used to suppress infrared radiation,the stealth characte-ristics of tail flame was systematically analyzed.The connotation of infrared radiation suppression was to change the infrared band and weaken the intensity of infrared radiation.By summarizing the research progress of fly ash based zeolite,the research progress of particulate aerosol inhibiting infrared radiation and spraying methods,combined with the analysis of aircraft tail flame radiation components,the existing problems and future development direction were summarized.Fly ash,as one of the solid wastes produced by thermal power plants,had the characteristics of high yield and low cost.It was proposed to synthesize zeolite molecular sieve from fly ash under certain conditions,and further prepare fly ash based zeolite loaded modified titanium dioxide material.As the particle application material,it could be used to suppress the infrared radiation of tail flame,which could turn waste into treasure. On the premise of reducing the preparation cost,it protected the environment and human health and promoted the sustainable development of society.The current research on the inhibition effect of zeolite components on infrared radiation was reviewed.The feasibility of their strong adsorption of high infrared radiation gas and photocatalytic performance of modified titanium dioxide were analyzed. The design of particle adsorption and shielding spray structure fully demonstrated the advantages of fly ash based zeolite.And the application prospect of this materials in aircraft tail flame stealth was put forward.

Key words: fly ash based zeolite, aircraft tail flame, infrared radiation, particle material, adsorption
