A lot of environmental problems such as global warning, air pollution and exhaustion of fossil fuels have been discussed frequently. Many researches have been underway in several countries to develop a propulsion system for an advanced aircraft to achieve low environmental loading. On the other hand, with the recent development of an aircraft, the propulsion system is required to have lighter weight, higher power and lower emissions. To satisfy these requirements, we have supposed a new cycle concept for advanced propulsion system, in which the combustion camber is eliminated; hydrogen gas is directly injected from turbine vane surfaces and combusted within turbine vane passages. However, to apply the cycle to practical use, there are problems of extremely high surface temperature and aerodynamic performance decrease by hydrogen combustion. It is well known that three-dimensional design approaches such as sweep, lean and twist decrease the secondary flow loss. However, there is no knowledge how these three-dimensional designs affect on the flow characteristics of the hydrogen-fueled turbine. In the present study, we focus on sweep. To clarify the sweep effect on the surface temperature and performance of the hydrogen-combustion turbine, three-dimensional numerical simulations based on RANS are carried out. We find that the swept vanes with positive sweep give the aerodynamic performance. On the other hand, the swept vanes with negative sweep suppress the vane surface temperature.
