在役军机隐身优化设计与改造技术研究

Research on Optimized Stealth Design and Transformation Technology of Military Aircraft in Service

对在役军机进行隐身化改造升级,对提高其战场生存能力和作战效能具有非常重要的军事价值。从作战使命与需求、气动与安全特性、隐身特性和增重限制等角度,分析了在役飞机进行隐身化升级的技术特点和要求,同时进一步明确了进行隐身改造的多类型隐身材料的优缺点,并探讨了对在役飞机不同部位进行隐身改造的技术措施。结果表明,对于在役军机座舱、进气道、机身等强散射部位的特征缩减,需有效平衡增重和隐身特性需求,选用质量轻、韧性强、吸收性能优异的隐身处理措施,以提升其综合性能。

It is of great military significance for us to make stealty transformation and upgrading of the military aircraft in service to improve its battlefield survivability and operational effectiveness.The technical features and requirements in optimized stealth design and transformation and upgrading of military aircraft in service from the aspects of combat mission and requirements,aerodynamic and safety characteristics,stealth features,weight restrictions etc. are analyzed.Advantages and disadvantages of multiple-type stealthy materials used for stealthy transformation were specified.And the technical measures for stealthy transformation for different parts of in-service military aircraft are also discussed.The results show that for the feature reduction of the strong scattering parts such as cabin,inlet and fuselage of military aircraft,it is necessary to effectively balance the requirements of weight gain and stealth characteristics,and the stealth treatment measures with light weight,strong toughness and excellent wave absorption performance are selected to improve the comprehensive performance.
