航空发动机技术成熟度评价方法应用研究

摘要

In order to improve the capacity of control risk in Chinese aeroengine development and provide the basis of the decision-making, a readiness assessment method that was used in aeroengine development was presented by taking the advanced theory and practical abroad as reference. The method included the technology readiness level control required in the life cycle of aeroengine development, critical technology element identification, technology readiness assessment criterion, technology readiness assessment tool and so on, and the method was proved reasonable and feasible through one pilot project. It will be a useful reference to technology readiness assessment in Chinese aeroengine development.%为提升中国航空发动机研制项目中技术风险的管控能力，支撑项目决策，根据中国航空发动机研制特点，结合国外技术成熟度评价的成功经验，提出了1套适用于中国航空发动机研制的技术成熟度评价方法，重点针对航空发动机全生命研制周期内的技术成熟度等级控制要求、关键技术元素的识别方法、技术成熟度等级评价标准、技术成熟度评价工具等方面进行了介绍。通过选取典型项目作为试点进行验证，证明该方法有效、可行，能够实现项中技术风险的识别与管控，为中国航空发动机研制中技术成熟度评价方法的应用提供借鉴。
