The aim of this research is to develop a hybrid device that integrates the passive and active flow control mechanisms to work cooperatively and additively to reduce aerofoil noise and improve superior aerodynamic performances. The research aim will be in two parts: (A1). Develop and optimise the next generation aero-acoustic and aerodynamic devices through cooperative ability to enhance aerodynamic and aero-acoustic performance through assessment over a broad range of loading conditions and flow speeds. (A2). To integrate the hybrid devices into the structure of the aerofoil through researching advanced materials and manufacturing techniques required in the development stage.

本研究的目的是开发一种混合装置，集成被动和主动流量控制机制，以协同和相加的方式工作，以降低翼型噪声并提高卓越的空气动力性能。研究目标分为两部分：(A1)。通过合作能力开发和优化下一代空气声学和空气动力装置，通过对广泛的负载条件和流速进行评估来增强空气动力和空气声学性能。 （A2）。通过研究开发阶段所需的先进材料和制造技术，将混合装置集成到翼型结构中。
