This research studies a cone-derived waverider, the airframe favorable for its high L/D characteristic. The study waslooked for design parameters that relates to the major concern of supersonic commercial aircraft, the sonic boom andaerodynamics performance. The numerical simulation is conducted under the condition of supersonic flight to analyze itsboom characteristics. After investigating three design parameters, the azimuth angle (ϕ), cone angle (δ) and R0 to observethe over pressure, L/D, CL ,CD and CM . The multi-objective optimization is conducted to study how each variableaffects to objectives of interest. Sensitivity analysis was employed to analyze how each variable corresponds to each other.The PCE-based Sobol indices were used as the analysis tool. The effect of design variable, δ and R0 corresponding toobjectives CL ,CM and overpressure were analyzed the main effect, interaction effect and total effect. As a result, thecone-derived waverider shows a significant trait to be able to reduce sonic boom while provides high lift force at the sametime.
