摘要
利用二次曲线方法与基于类型函数和形状函数的CST方法,提出一种类X-37高超声速飞行器气动外形,进行机体的气动力分析和控制舵的匹配设计,研究飞行器的气动特性和操纵效率问题。研究表明,该方案可以获得较高的配平攻角,有较高的容积利用率和机动控制效率,可以作为未来航天飞行器的潜在可行方案。
A X-37 analog transporter configuration is proposed via biconic cross section design method and ＂class function and shape function transformation technique＂（CST）. The configuration is investigated, the stabilizers and control surfaces, such as V-shape ruddervators, body flap and flaperons are designed and matched, and the aerodynamic characteristics and the control efficiency are studied. The detail research indi- cates that the proposed transporter has a high trimming angle of attack and big volume utility ratio, the hy- personic stability derivatives show that the transporter is static and dynamic stable in both lateral and direc- tional directions at high trimming angle of attack. The present work focus on the conceptional design meth- od, the proposed X-37 analog configuration is one of the feasible transporter choices.
