- Abstract
- An intake is a device for supplying external air into the internal engine of an aircraft. In order to reduce the radar reflection on the engine face for reducing the observability, intake has an S-shaped duct. When applied to s-duct of the fuselage, the uniformity of the flow at the engine face varies depending on the state of flow at the inlet of the duct. In this study, the effect of active flow control at the inlet of S-duct was analyzed using a commercial computational fluid dynamics tool. The purpose of this study is to investigate the effect of the active flow control factors for an RAE M 2129 S-duct. The study was conducted by changing the position, length, and mass flow of the active flow control, and the mass flow was within 1% of the s-duct internal mass flow. The OLHD method was applied to 15 models for three factors and the k-ω SST turbulence model was used to predict the flow separation and secondary flow by adverse pressure gradient. In conclusion, the performance of the S-duct was found to have the greatest influence on the position of the flow control, and it was confirmed that the performance was the worst when the position was 0 in the duct standard.
