保形油箱的隐身与气动设计

Aerodynamic-stealth design of conformal fuel tank

在预测保形油箱对飞机隐身性能和气动性能影响的基础上,通过一个典型设计范例研究了保形油箱的隐身与气动设计方法,并与传统副油箱的效果进行了对比.比较结果表明,同样条件下,保形油箱对飞机性能造成的不利影响要比普通副油箱小得多;如果设计适当,保形油箱甚至完全可以改善飞机的隐身和气动性能.在设计过程中,对飞机上可能安装保形油箱的位置及优劣进行了分析,这些经验可以推广到一般保形外挂和其它型号飞机上.总结了保形油箱隐身与气动设计的规律,并在保形油箱设计的基础上,结合其它外挂物的特点,给出了一般保形外挂的隐身与气动设计的特点和设计原则.

Based on the prediction of the influence of aircrafts＇ stealth and aerodynamics characteristics by conformal fuel tanks, the method of aerodynamic-stealth design of conformal fuel tanks through a design model was studied, and the effects were compared with the traditional auxiliary tanks. Results show that the conformal fuel tanks bring less bad effects than the traditional auxiliary tanks in the same condition. If well designed, the conformal tanks could improve the performances of the aircraft rather than worsen them. In the designing, the research on the position where conformal tanks placed and the effects was conducted. The experience could be easily extended to other conformal carryings and other type of aircrafts. The rules of aerodynamic-stealth design of conformal fuel tanks were concluded. Based on these results, combined with the characteristics of other carryings, the principles and characteristics of the design of ordinary conformal carryings were also given for consult.
