应我校航空学院飞行器环境控制与生命保障工信部重点实验室余雄庆教授的邀请，美国飞机总体设计专家Tony Hays于2019年3月18日至22日访问了我校，并于3月20日与21日做了题为“Aircraft Design for Reduced Carbon Emissions”与“Supersonic Transports – Past, Present and Future”的学术报告。报告从全球变暖所引发的一系列环境变化问题入手，引出了全球能源对于碳燃料的依赖。报告探讨了支撑飞行器运行的可持续性能源，例如氢能、太阳能或电能。21日的报告则主要探讨了超音速飞行器的过去、现在和未来，报告丰富多彩、生动有趣，报告会由余雄庆教授主持。会后，Tony Hays专家与我校师生做了深入的交流、探讨及问题解答。
Tony Hays专家在飞行器领域自1962年加入Bristol Siddeley Engines（后成为Rolls-Royce）当学徒起有着超过50年的工作经验。他在英国布里斯托大学拿到学士学位，后在美国麻省理工大学取得航空宇航专业的理学硕士学位。后其在洛克希德马丁公司工作了30年，主要负责飞行器的设计。
Tony Hays has worked in the aerospace industry for over 50 years, having joined Bristol Siddeley Engines (which later became part of Rolls-Royce) in 1962 as an apprentice. He holds a B.Sc. degree in Aeronautical Engineering from Bristol University in the UK, and an S.M. degree in Aeronautics and Astronautics from MIT. He worked at Lockheed Martin for 30 years, mostly in aircraft conceptual design. Designs he has worked on include a vertical takeoff airliner (Hawker Siddeley 133/141), Lockheed L1011 derivatives, supersonic transports, and a single stage to orbit scramjet-powered aircraft (National AeroSpace Plane). He has also been involved in other areas of aircraft design and operation, including aeroacoustics, flight crew training (Lockheed C-130J), flight manual development (C-130J and Lockheed C-5M), and market development (De Havilland Canada DHC-7). He has taught classes in aircraft design at several universities in the United States and China.
