航空发动机领域，国外从四代机研制开始，普遍采用提前开展技术验证机研究的发展思路，使型号发动机中应用的新技术能得到充分的前期技术验证。美国典型的四代机发动机F119，在预研阶段，以充分的核心机技术验证为基础；进入型号阶段后，核心机上采用同期开展的各项技术验证计划中经验证的成熟技术；设计定型后，以核心机为验证平台，派生发展途径从系列化已逐渐跨越到多用途层面。国外四代机发动机的核心机的技术发展战略，对我国发动机的研制具有很好的指导、借鉴作用。

Technology demonstrator approach has been adopted to fully mature the new technologies ap-plied in prototype since the 4th-generation-fighter engine development. The core engine development strate-gy abroad, especially for F119 was illuminated. In the phase of advanced development, core engine technol-ogies demonstration was the basis;in the phase of engineering development, prototype mature technologies verified in various programs were adopted in the core engine; after the design has been finalized, the core engine became a platform for demonstration. Derivative development approach was not only in series, but al-so of versatile applications. The technology development strategy for core engine abroad is referential for en-gine development in China.
