摘要
颗粒介质的抗红外辐射方式是飞行器尾焰隐身的重要手段之一。为促进颗粒系材料抑制红外辐射的研究和发展,对尾焰隐身进行了系统分析。红外辐射抑制的内涵在于改变红外波段和削弱红外辐射的强度。通过综述粉煤灰基沸石的研究进展、颗粒材料气溶胶抑制红外辐射和喷射方式的研究进展,结合飞行器尾焰辐射组分分析,总结了目前存在的问题和日后的发展方向。粉煤灰作为火力发电厂产生的固体废弃物之一,具有产量高、成本低的特点。提出将粉煤灰在一定条件下合成沸石分子筛,并进一步制备粉煤灰基沸石负载改性二氧化钛材料,将其作为颗粒系应用材料,用于尾焰红外辐射的抑制,可以实现变废为宝,在降低制备成本的前提下保护了环境与人类健康,促进社会的可持续发展。对目前沸石各成分抑制红外辐射效果的研究进行了综述,利用其对高红外辐射气体的强吸附性以及改性二氧化钛的光催化性能进行可行性分析,设计了颗粒吸附和遮蔽喷射结构,充分展示了粉煤灰基沸石的优势,并对该材料在飞行器尾焰隐身方面的应用前景提出展望。
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 characteristics 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.
