Hypersonic systems will provide a revolution in commercial transport, space access lower power density, and future NATO missions global reach in 2 hours. Although hypersonic technology has significantly matured over the last 40 years technical challenges remain intake design and optimization, combined cycle engines, integration engine airframe, thermal management. The fact that several international research programs are running demonstrate a strong interest from several countries. Defence interest in a Mach 4 8 aircraft hydrocarbon fuel include theater aircraft and weapons, missiles tactical and strategic and transport. A Mach 8 to 18 hydrogen fuel would include global aircraft and weapons and missiles. Regarding survivability, today speed is more effective than improved radar cross section. The objective of the Lecture Series is to provide clear guidelines regarding the design of the propulsion unit and integration into the airframe. First the intake physics, design and optimization was addressed. Turbine based cycles and rocket based cycles was considered. An important issue discussed was the thermal management of both the engine and vehicle. Issues related to the potential use of new synthetic fuels were also addressed. The Lecture Series was a unique opportunity to bring together experts from different horizons and raise fruitful discussions. The main topic of this lecture series is the engine integration in high speed vehicles. An important concern to be treated is the thermal management of the engine, fuel, hot structures. Other topics to be covered comprise intakes physics design optimization, overall engine cycle analysis, and new synthetic fuels. The program was completed with discussions on current demonstrator programs, based on the experience acquired in advanced demonstrators in USA, Europe and Asia.
