摘要
The feasibility of integrating environmental considerations into aircraft conceptual design is explored. The approach involves designing aircraft to meet specific noise and emission constraints while minimizing cost. A detailed noise prediction code (NASA Langley Research Center's ANOPP) is coupled with an engine simulator (NASA John R. Glenn Research Center's NEPP) and in-house aircraft design, analysis, and optimization modules. The design tool and a case study involving a 280-passenger airliner are discussed. The study includes operational aspects, such as steeper approaches and takeoff thrust cutback for noise reduction. Low-emissions (CO2 and NOx) designs are also evaluated. Results show that optimized designs featuring cumulative noise reductions of up to 25-dB effective perceived noise level may be obtained with as little as a 3% increase in operating cost. The study also establishes a tradeoff between noise and emissions performance.
