俄罗斯PD-14发动机项目特点分析

The analysis on development characteristics of Russian PD-14 engine

针对俄罗斯第5代大涵道比涡扇发动机PD-14开展研究。通过分析PD-14发动机的研制背景和研制需求,总结出当前俄罗斯航空发动机研制过程中科技储备先行、需求牵引设计、市场导向产品的典型特点。同时研究表明,在近年来俄罗斯航空工业改革重组、优化资源、复兴发展的背景下,PD-14发动机采用通用核心机设计理念和现代化研发管理模式,在自主研发的道路上取得了巨大进步。

The development of the Russian fifth generation of high bypass ratio turbofan engine PD-14 was studied.Through the analysis of PD-14 development background and requirements,the typical develop⁃ment features for current Russian aero-engines were summarized,which included making technology re⁃serve in advance,conducting design according to requirements and making products guided by market.In recent years,Russia implemented reform and restructure of aviation industry to carry out unified manage⁃ment and superior resources allocation to realize renaissance of Russian industry.Under this background,the versatile core engine design and modern management mode were adopted in the PD-14 aero-engine de⁃velopment which achieved giant progress in the independent research and development.
