Development of Advanced Wing Solutions 2 (DAWS 2)

DAWS 2（先进机翼解决方案的开发）将继续在ATI资助的DAWS项目中开展的工作。重点是开发超高效技术，以减少燃料消耗和重量，而不依赖于燃料的选择。DAWS 2将把该技术开发成一种新的高构建率产品的工业应用解决方案。主要应用将是一种新的中短程飞机，尽管这些技术也适用于远程飞机。这些技术将通过增加新飞机产品的展距，使高展弦比机翼的开发成为可能。高展弦比机翼实现减少阻力，因此燃料消耗。利用减轻载荷、减轻重量和折叠翼尖的技术，可以进一步减少机翼的燃油消耗。为了表现新技术的行为，需要对现有工具进行改进。这涵盖了数值模拟的改进，包括在设计空间和非线性设备的具有挑战性的区域中表示流。它将包括改进耦合结构模型和计算流动力学的方法。(CFD-CSM)。它还将涵盖校准先进仪器和用于评估新技术的WTT（风洞测试）技术的能力开发。

DAWS 2 (Development of Advanced Wing Solutions) will continue the work started in the live ATI funded DAWS project.The focus is on development of Ultra Efficient technologies to cut fuel burn and weight, independent of the fuel choice. DAWS 2 will develop the technology into industrially applicable solutions for a new high build rate product.The primary application would be for a new short to medium range aircraft, although the technologies would also be applicable for long range aircraft.These technologies will enable development of a High Aspect Ratio wing through additional span for a new aircraft product. High Aspect Ratio wings achieve reduced drag and hence fuel burn. Using technology for load alleviation, weight reduction and folding wing tips, the fuel burn of the wing can be reduced further.To represent the behaviour of the new technologies, improvements need to be made to existing tools. This covers improvement of numerical simulations including representation of the flow in challenging areas of the design space and for non-linear devices. It will include improvement of methods for coupling structural models and computational flow dynamics. (CFD-CSM).It will also cover development of capabilities for calibrating advanced instrumentation and WTT (Wind Tunnel Test) techniques for assessing the new technology.
