    Abstract
  • The S-shaped inlet working with the turbofan engine was discussed by using ground test and computational fluid dynamics (CFD) codes. A full scale S-shaped inlet model had been made of glass fiber reinforced plastic. The model was installed in front of the JT15D-4 turbofan engine, with the results obtained from the full scale matching ground test at Beijing. Static pressure,total pressure recovery and total pressure contours were presented. Under the same working condition, the performance of the S-shaped inlet was developed by using CFD codes. Based on comparison of CFD code to full scale measured test data, they match well. It means that on one hand the S-shaped inlet was designed properly according to the engine and they can match work together, on the other hand the CFD codes are shown to predict total pressure contours at the duct exit accurately, the CFD codes could be used for the inlet design.
