摘　　要：基于提高W型无尾翼身融合布局大迎角俯仰操纵能力的设想,探索一种机身下表面嵌入式俯仰操纵舵面的新概念。采用CFD方法,研究纵向两个位置、两种弦向长度组成的四种机身下表面嵌入式舵面构型对无尾气动布局性能的影响及其流动机理,分析了嵌入式舵面提供纵向操纵控制的作用原理。研究结果表明,下表面嵌入式舵面可作为无尾布局大迎角俯仰操纵的有效补充措施,为无尾布局大迎角俯仰操纵提供了新的技术途径,具有进一步深入研究的价值。To enhance pitching control ability of the W-type blended wing-body tailless configuration at higher angles of attack,the spoilers located on lower surface of wing-body are studied by numerical simulation method.Four kinds of LSP schemes are designed with the consideration of two positions along body axis direction and different chord lengths.Aerodynamic effects of different LSP scheme on the configuration and the flow mechanism was investigated.The action mechanism of lower surface spoilers to afford longitudinal maneuvering capability was analyzed.According to the results,the lower surface spoiler can support tailless configuration as an effective longitudinal control effectors at high angles of attack.The work in this paper provide a new way for longitudinal pitching control of tailless configuration at high angles of attack,which is worth to develop further study.
