| Summary: | In this study axisymmetric supersonic intake model was tested at Mach number of
4. The intake geometry of SR-71 supersonic aircraft was used here for testing a
scale model. Static and total pressure measurements in the duct were used to
observe shock effect on internal flow. To improve pressure recovery of intake,
surface correction of cone was attempted. By using taper plug different blockage
area of exit were obtained to locate normal shock in throat for minimum loss of
pressure. Redesign of model, pressure instrumentation, principle of intake operation
and data analysis are covered in detail in the thesis. Results of pressure values
showed good agreement with simple 1 - D compressible flow calculations. |
