Architecture Design and Evaluation of Electrical Trimmable Horizontal Stabilizer Actuation System for More Electric Aircraft

电动水平安定面作动系统是一种冗余式的电力驱动和复杂机械承载传输的机电作动系统,主要用于驱动水平安定面完成飞机的俯仰配平工作。然而当前电动水平安定面作动系统的架构设计缺少系统性、完整性的设计流程及评估指标,导致新产品开发周期长、可靠性不高、设计裕量大。针对这一问题,从轻量化指标出发,本文提出了一套系统性的架构设计及评估方法。该方法从系统余度架构设计开始,利用启发式算法确定系统余度数目及余度方案配置,对系统各部件展开了详细的分析及筛选,并基于相似率对各部件参数进行设计,在得到的32种可行方案中选取了4个典型架构,分析了余度配置形式、部件功能形式以及关键设计参数等对架构重量的影响。最终实现了架构的自动生成、筛选和定量评估,为国产电动水平安定面作动系统的设计研制和冗余式机电作动系统在关键飞控舵面上的应用提供技术支撑。

Electrical trimmable horizontal stabilizer actuation system is a special electromechanical actuation system with redundant electrical power drive paths and complex mechanical transmission loads,which drives the trimmable horizontal stabilizer to achieve the pitching work of the aircraft.However,the current architecture design of the electrical trimmable horizontal stabilizer actuation system lacks a systematic and integrated design process and evaluation index,which leads to long development cycle,low reliability,and a large design margin of the new system.To solve this problem,a systematic architecture design and evaluation method based on the lightweight index is proposed.At the beginning of the design of the system redundancy architecture,a heuristic algorithm is used to determine the number of system redundancy and the configuration of the redundancy scheme.The components of the system are analyzed and reviewed in detail,and the parameters of each component are designed based on the scaling laws.From the 32 possible schemes,4 typical architectures are selected to analyze the influence of the form of the redundancy configuration,form of component function and the main design parameters on the weight of the architecture.Finally,the automatic generation,screening and quantitative evaluation of the architecture are realized,which provides technical support for the design and development of a domestic electrical trimmable horizontal stabilizer actuation system and the application of redundant electromechanical actuation system for the key flight control surfaces.
