Objectives / Committees

Our truly international conference brings together experts in high-speed vehicles from around the World. Our objective is to enhance the visibility of competencies, events, and publications in high-speed vehicle science and technology. We encourage scientists to publish their research outcomes in significant peer-reviewed Aeronautical and Space Journals published by the Council of European Aerospace Societies (CEAS), fostering dedicated international HiSST conferences to ensure a multi-national exchange of ideas.

The International HiSST conference occurs every 18 months, supported by an International Technical Committee, in partnership with CEAS. Our conference program features keynote speeches, global status reports from our International Technical Committee members, a substantial number of technical papers and posters, some technical visits to key points of interest in the high-speed vehicles field. We invite your participation in social programs, award ceremonies during a gala dinner.

As previous HiSST editions, HiSST2025 will provide the perfect event to share your work with your peers and develop open and fruitful interactions with specialists from research institutions, academia, and industry worldwide, covering all aspects of high-speed aerial and space vehicles development from fundamental research to final products:

• Leading specialists will provide a global view of worldwide R&D effort in the field of High Speed flight and will address some key topics.
• Numerous parallel technical sessions will allow you to discover the latest results obtained worldwide.
• Focused technical workshops on high-speed vehicle science and technology will allow you to share ideas with your peers and develop some common activities in a collaborative forum
• An exhibition area where sponsors & exhibitors will showcase their innovation, research, technology and latest technical results.
