Impacta - Improving the Propulsion Aerodynamics of Turboprop Aircraft

燃料成本的增加和环境压力的增加凸显了对更高效、更清洁和更安静的飞机的需求。与同等涡轮风扇驱动的飞机相比，涡轮螺旋桨飞机可节省高达30%的燃油消耗。Dowty Propellers目前是全球仅有的两家大型复合螺旋桨叶片及相关系统制造商之一。Dowty已经确定了一些空气动力学和声学创新，以改善噪音，进一步提高涡轮螺旋桨飞机的效率，从而增加市场潜力。Dowty Propellers将与飞机研究协会（ARA）和利物浦大学合作，研究这些空气动力学和声学设计，开发先进的分析工具，并进行风洞测试，以将这些技术开发成实际的解决方案。

Increases in the cost of fuel and increasing environmental pressures has highlighted the need for more efficient, cleaner and quieter aircraft. Turboprops offer up to 30% savings in fuel burn compared to an equivalent turbofan powered aircraft. Dowty Propellers is currently one of only two global manufacturers of large composite propeller blades & the associated systems for these aircraft. Dowty has identified a number of aerodynamic and acoustic innovations to improve the noise and further improve the efficiency of turboprop aircraft thereby increasing market potential. In collaboration with the Aircraft Research Association (ARA) and the University of Liverpool, Dowty Propellers will research these aerodynamic and acoustic designs, develop advanced analysis tools and perform wind tunnel tests to develop these technologies into practical solutions.
