摘要： Embodiments of the invention provide an aircraft configuration that provides for increased engine noise shielding for community noise reduction, while still providing desirable aerodynamic attributes such as good spanwise lift distributions and good structural integration without excessive wing surface area. Specifically, the aircraft is configured to have a longer-chord inboard wing portion and a shorter-chord outboard wing portion. The aircraft engines are positioned in major part over the longer-chord inboard wing portions such that communities below the wing are at least partially shielded by the inboard wing portion from the engine noise. Embodiments of the invention also strategically position fowler flaps or other chord-increasing devices in the region of the wing proximate the engine. Since the fowler motion increases the effective chord of the wing as the flaps are extended, the flaps may be deployed to increase the shielding characteristics of the wing.
摘要翻译：本发明的实施例提供了一种飞机配置，其提供用于社区降噪的增强的发动机噪声屏蔽，同时仍然提供期望的空气动力特性，例如良好的翼展式升力分布和良好的结构整合，而没有过多的机翼表面积。具体地说，该飞机被构造成具有较长的弦内侧翼部和较短的弦外侧翼部。飞机发动机主要部分位于较长的弦内侧翼部分上，使得机翼下方的社区至少部分地被内侧机翼部分与发动机噪声屏蔽。本发明的实施例还在靠近发动机的翼的区域中策略性地定位渔翼襟翼或其他和弦增加装置。由于当翼片延伸时，飞轮的运动增加了机翼的有效弦，所以翼片可以被展开以增加机翼的屏蔽特性。
