随着船舶航行对燃气轮机动力要求的提高，传统的试验-设计反复迭代方式无法高效支撑设计需求，数字孪生技术实现虚拟实体与物理对象的精准映射，支撑传统设计体系向数字化设计转变。本文论述燃气轮机在设计阶段面临的挑战，归纳多保真且具有时效性的数字孪生体构建技术，总结高维模型的降阶方法。为形成闭环的全生命周期管理，给出设计阶段数字孪生体的衍生策略，指出动态自适应所需的关键技术，在此基础上，对数字孪生技术在燃气轮机设计领域的研究前景进行展望。
The traditional trial-design iterative method cannot efficiently support the design requirements of marine gas turbine, as the power requirements of ship navigation continue to improve. Digital twin technology aims to achieve the accurate mapping between virtual digital twin model and physical space gas turbine, which has the ability to supports the transformation of design system of gas turbine from traditional trial-design to digital design. In this study, the challenges existing in the design stage of gas turbine are discussed. The construction technologies of digital twin which contains a series of multi-fidelity and time-sensitive models are analyzed. The reduction methods for introducing high-dimensional models in digital twin are summarized. In order to form the closed-loop life cycle management of the marine gas turbine, the derivative strategy of the digital twin in the design stage is discussed. The key technology of dynamic performance adaptation is pointed out. On this basis, the research prospect of digital twin technology for the design of the gas turbine is prospected.
