To reduce the risk of probably no solution for solving the problem of formulation based on optimization technique,the conceptual design method and model of double-base solid propellant formulation based on quality function deployment (QFD) and axiomatic design(AD) were proposed.A modified double-base propellant formulation example was designed by the conceptual design system of formulation.The application effect of the model in the conceptual design system of propellant was showed.Results show that in the conceptual design step of formulation,the formulation to preliminary solve is rquired to basically satisfy the index requirement of formulation functional components and their boundary content to ensure the detailed design (optimization design) of subsequent formulation has solution.In traditional design work of formulation,a new method according to " conceptual design+ detailed design +performance prediction + redesign" can effectively avoid the optimization risk from solution,improve the efficiency of formula design and reduce the cost of formula design.%为了降低基于优化技术求解配方问题可能无解的风险,提出了基于质量功能展开(QFD)和公理化设计(AD)的双基系固体推进剂配方概念设计方法和模型,利用配方概念设计系统设计了一个改性双基推进剂配方实例,展示了该模型在推进剂配方概念设计系统中的运用效果.结果表明,在配方概念设计阶段初步求解基本满足指标要求的配方功能成分及其边界含量,确保后续配方详细设计(优化设计)有解.在传统的配方设计工作中,按照“概念设计+详细设计+性能预估+再设计”的新方法能有效避免优化无解风险,提高配方设计效率,降低配方设计成本.
