摘　　要：随着飞行器对航空发动机的能力需求和发动机自身技术难度的提高,其研制的风险、周期、成本不断上升,对采办模式也提出了更高的要求。提出将发动机采办过程数字化的思路,从联合需求分析入手,运用多维缩放技术,以虚拟样机各维度的仿真模型为基础,开展一体化仿真,实现对技术方案的评估;以工作分解结构为纽带,建立技术方案、进度和费用等的映射关系,构建发动机虚拟采办的基本框架,实现物理域模型与业务域模型的有效集成,可快速预测进度和费用,提升采办评估的科学性。Follow the increasing demand of aircraft for aero engine’s capabilities and because of the increase of engine’s own technical difficulty,the risks,cycles and costs of the engine development is rising,and the high demand of traditional acquisition model is urgently needed.The idea of digitalized aero engine acquisition is presented,which starts from joint analysis,applies multi-dimensional scaling technology,carries out integrated simulation based on the models of each dimension of virtual prototype,and realizes the evaluation of technical scheme.The mapping relationship among technical solutions,schedules and costs etc.are established,and a basic framework for simulation based acquisition of engines is constructed by using the work breakdown structure as the link,to realize the effective integration of physical domain models and acquisition process models,which can quickly predict progress and costs,improve scientific nature of acquisitive evaluation.
