Research on Ram Air Turbine Blade Properties

The Ram Air Turbine system is the emergency power system of aircraft. As the key parts, the blades aerodynamic characteristic effects the system properties. In this article, CFD numerical method will be used to research four blades properties of ram air turbine. We compare the blades work properties of each working condition, so that we can get which design is better. We used the CFD numerical method to design the RAT blade, we hope this method will be used in our future products design.
