AbstractThe aft-boom shaping for a small supersonic transport is performed and is validated by the wind tunnel test. First, the parametric study of horizontal stabilizer shape using the low-fidelity design tool is conducted in order to fragment the aft boom into two shock waves. Though the nacelle is not modeled in this design, the negative effect of nacelle pressure waves on the aft-boom is considered, and pressure waves caused by the horizontal stabilizer is strengthened to realize the fragmentation. Results show the importance of inverse camber and extended root chord length in order to realize both low-drag and low-boom. Then, wind tunnel test and high-fidelity CFD (FaSTAR) analysis for the designed shape without nacelle are performed. Near-field pressure signatures obtained by wind tunnel test and FaSTAR analysis agree well. Finally, FaSTAR analysis is performed for the designed shape with nacelle and shows that the aft-boom is successfully fragmented into two shock waves even though the coalescence of these two shock waves is advanced by the nacelle expansion wave.
