翼型几何参数对隐身特性的影响研究
Investigation on the Effects of Geometric Parameters on Airfoils′ Stealth Characteristics
摘要
Abstract
To obtain the effects of airfoil geometry on Radar Cross Section(RCS),the RCS characteristics of a series of reflex airfoils were investigated using the method of moment(MOM) with high accuracy.These airfoils are usually used in the design of blended-wing-body(BWB) airframe and are modeled by the parametric method.The MOM is validated on the NACA0012.The bistatic RCS of NACA0012 agrees well with the data of references.An effective factor was defined to qualify the effects of geometric parameters on the RCS.Meanwhile,the effects of geometric parameters on aerodynamic characteristics were also considered.Based on the effective factor analysis using table values,the geometric parameters were divided into three categories in the RCS design.关键词
