摘要

飞机设计涉及复杂的系统集成,必须符合一系列要求,这些要求由认证机构、客户、制造商和市场研究机构制定。从航空公司的传统角度来看,一架有趣的飞机是一架能够以最小的成本产生最高收入的飞机——一架利润最大的飞机。然而,在后来的几年里,航空业正在迅速扩大对什么是值得购买的飞机的考虑范围。在规划飞机时,不仅要考虑经济因素,还要考虑环境因素——这一趋势是由具有环保意识的乘客推动的。为了顺应这一趋势,飞机概念设计纳入了对飞机噪音和排放进行初步评估的方法。随着越来越多的方法可用来解决这些问题,在最合适的方法之间进行选择变得更加困难。本工作分析了一些方法,以便选择其中的一个子集。目标是评估这些方法并将其整合到飞机概念设计的框架中。为了测试设计方法和优化技术,作者选择了两种测试飞机类别:第一种是远程、横贯大陆的喷气式飞机;还有一架中型支线飞机。提出并分析了基于噪声足迹、直接运行成本和排放概况或其组合为目标的优化设计任务。

Conceptual Optimal Design of Environmentally Friendly Airliners: AReview of Available Methodologies and their Integration into a ConsistentFramework for Everyday Use
Airplane design involves complex system integration and must comply with a set of requirements, which are set up by certification authorities, customers, manufacturing, and that coming from market studies. From the traditional perspective of an airline, an interesting airplane is one that is capable of generating the highest revenue with minimum cost-a maximum profit airplane. In later years, however, the airline industry is swiftly broadening its consideration of what constitutes a nice-to-buy airplane. Not only economics but also environmental considerations are taking part in fleet-planning considerations-a trend spurred by environmental-aware passengers. In a move to comply with this trend, airplane conceptual design has incorporated methodologies for preliminary assessment of airplane noise and emissions. As more approaches become available to address these issues, the choice between the most suitable methodologies becomes tougher. The present work analyzes some methodologies in order to select a subset of them. The objective is the evaluation of such methodologies and their integration into a framework to airliner conceptual design. In order to test the design methodologies and the optimization techniques, the authors selected two test airplane categories: first, a long range, transcontinental jet; and a mid-size regional jet. Design tasks based on optimization with noise footprint, direct operational cost, and emission profile or a combination of them as objectives are presented and analyzed.
