| 요약 | In modern turbofan engines powering commercial aircraft, the fan is becoming the dominant source of noise at takeoff and landing. Understanding and modeling of the fan noise source, and the interaction of the emitted sound with the airframe, are |
| 요약 | The experimental effort entailed the design and construction of a subscale ducted fan rig that includes all the relevant components of the turbofan engine and simulates accurately the sound emission generated by the fan of such engines. The duct |
| 요약 | The theoretical effort comprises the following steps: (a) extraction of the harmonic content of the measured noise through use of the Vold-Kalman filter |
| 요약 | Far-field source parameterization shows that the wavepacket can be modeled as a short cylindrical disturbance surrounding the exit of the nozzle. The resulting modeled sound field captures the most prominent experimental far-field and near-field |
