Investigation of Large Fold Angles of a Semi Aeroelastic Hinged Wing Tip

半气动弹性铰接翼尖概念是由空中客车公司与布里斯托尔大学共同开发的，其理念是允许翼尖在地面移动以适应机场大门，在飞行中释放被动运动，以减轻阵风载荷并提高滚转效率。这是一种实现高展弦比机翼的方法，在不增加重量的情况下，具有显著的航空性能优势，从而提高飞机的燃油效率，减少对环境的影响。该学生将使用MATLAB和基于有限元的模型开发一系列非线性计算气动弹性模型，以预测折叠翼尖的响应特性并进行参数研究。将进行风洞试验，并可能进行飞行试验（使用AlbatrossONE无人机演示机），以研究与非常大的翼尖折叠角度相关的气动弹性现象，例如在地面上被动展开或飞行中无意的翼尖过度折叠，并验证数值模型。

The Semi Aeroelastic Hinged wing tip concept has been developed by Airbus with the University of Bristol and is based on idea of allowing a wing-tip, that can be moved on the ground to fit airport gates, to be released for passive movement in-flight to enable gust loads alleviation & improved roll efficiency. It is a means to achieve very high aspect ratio wings with significant aero performance benefits without any increased weight, thus improving the aircraft fuel efficiency and reducing the environmental impact.The student will develop a series of non-linear computational aeroelastic models using MATLAB and FE based models in order to predict the response characteristics of the folding wing-tip and to perform parameter studies. Wind tunnel tests will be performed, plus potentially flight test experiments (using the AlbatrossONE UAV demonstrator aircraft), to investigate the aeroelastic phenomena associated with very large wing tip folding angles such as passive deployment on the ground or inadvertent over-folding of wing tips in-flight, and to validate the numerical models.
