| 英文摘要: |
| Nuclear-powered turbine engines,which integrate the high energy density of nuclear reactors with the high power density of
turbine engines,have garnered significant research attention.This paper reviewed the development history of nuclear-powered turbine
engines in the United States and examines more than ten representative conceptual designs.It analyzed the system composition,operating
principles,and performance characteristics of each design,thereby clarifying the main trajectory of conceptual research in this field.Based
on this review,key technologies essential for nuclear-powered turbine engines were explored,identifying critical technology clusters includ?
ing overall system design and matching,high-efficiency thermal management,health monitoring and maintenance,advanced control,and
radiation shielding.This study provides a reference for technology path selection and the advancement of nuclear-powered turbine engine
development. |
