一般注記Japan Aerospace Exploration Agency (JAXA) has conducted a low-boom and low-drag design considering propulsion airframe integration for a 50-seat-class supersonic transport. In this study, three technical targets in terms of airport noise, lift-to-drag ratio, and sonic boom were defined. Design results complying with three technical targets are summarized in this paper. First, engine specifications are optimized to comply with ICAO noise standards. In this optimization, only the engine (jet) noise is considered, and the engine exhaust velocity that has strong impact on jet noise is constrained. The objective function to be maximized is the range performance. Then, the engine nacelle is designed based on the optimized engine specifications and is integrated with the low-boom-designed airframe considering range performance and sonic boom loudness. Finally, technical targets on lift-to-drag ratio and sonic boom are validated by the Navier-Stokes analysis and wind tunnel tests.
