COLTS delivered a large Titanium Spacecraft Engine Casing prototype and MARS produced a database on the devices for active flow control. Work was equally developed by the European and Chinese side, in which each task involved partners from both areas.What are the key impacts?The two technologies promoted under this Sino-European partnership in aeronautics –the development of active flow control devices and casting of large Titanium parts– are still at a very early stage, but when having reached maturity, they will respectively lead to a significant reduction of the drag and on the weight of the aircraft envelope, streamlining the aerodynamic performance of the aircraft and ultimately enhancing fuel economy and reducing emissions.Both technologies are breakthrough innovations proposing completely new solutions compared to the current technologies: Flow control remains a paradigm not achieved yet, and casting of large Titanium parts relies on costly traditional methods.What are the added values and what were the biggest challenges of your cooperation?The long cooperation relationship has involved 60 partners, from both industryand public research sectors, as well as aeronautical clusters. In addition, the partnership would have not been possible without the support of the relevant authorities (the European Commission and the Ministry of Industry and Information Technology of China). Aligning so many stakeholders and delivering a meaningful outcome is at the same time the biggest challenge and the most added value of the cooperation.The partnership is still growing in the range of topics and number of partners, centralizing the most relevant Sino-European cooperation in the field.Websites:http://www.cimne.com/grain2/spacehome/1/0#http://ch-eu.cae.ac.cn/cn/index.aspx
