翼身融合(BWB)飞翼布局是未来新一代客机的热点方案之一,然而由于没有常规尾翼,面临着稳定性和操纵性方面的困难。为此,在一架250座级BWB客机布局设计研究基础上,根据平衡、增稳和机动等要求,设计了操纵面配置方案;根据适航要求和电传飞机飞行品质要求设定增稳目标,并将其直接纳入特征结构配置要求中,通过前向通道修正响应类型,保证获得与飞行阶段相适应的响应特征和满意的飞行品质参数;为了提高安全性,在增稳控制设计基础上,在指令回路增设了姿态保护和限制模块。研究结果表明,该设计方案能够提供较合适的稳定性和操纵性,控制增稳后具有满意的飞行品质,保护模块可达到预期效果。
Blended wing (BWB) wing layout is one of the hot topics for the new generation of passenger aircraft in the future. However, due to the lack of regular tailplane, the stability and maneuverability are faced with difficulties. Based on the research of layout design of a 250-seat BWB passenger aircraft, the control plane configuration is designed according to the requirements of balance, stabilization and maneuvering. The stability target is set according to the requirements of airworthiness and the flight quality requirements of teletype aircraft , And directly incorporate them into the requirements of the configuration of the feature structure. The response types are corrected through the forward channel to ensure the response characteristics and the satisfactory flight quality parameters that are suitable for the flight phase. In order to improve the safety, based on the design of the augmentation control, Attached to the command loop are attitude protection and limit modules. The results show that the design scheme can provide more suitable stability and maneuverability, control the stability of the flight with satisfactory quality, and the protection module can achieve the desired effect.
