Development of Advanced Wing Solutions 2 (DAWS 2)

DAWS 2(高级机翼解决方案的开发)将继续在ATI资助的DAWS项目中开始的工作。重点是开发与燃料选择无关的超高效技术，以减少燃料消耗和重量。DAWS 2将把这项技术开发成工业上适用的解决方案，用于新的高建造速度产品。主要应用于新的中短程飞机，尽管这些技术也适用于远程飞机。这些技术将使新飞机产品的大展弦比机翼开发通过额外的跨度。大展弦比机翼可以减少阻力，从而减少燃料燃烧。使用减轻负荷、减轻重量和折叠翼尖的技术，可以进一步减少机翼的燃料消耗。为了体现新技术的行为，需要对现有工具进行改进。这包括改进数值模拟，包括表示设计空间中具有挑战性的区域和非线性设备中的流动。它将包括结构模型和计算流动动力学耦合方法的改进。(CFD-CSM)，它还将包括用于校准先进仪器的能力的开发和用于评估新技术的WTT(风洞试验)技术。

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.
