The demand for supersonic vehicles is believed to boost in 
the incoming years. This VKI/RTO lecture series reviews 
the current state of the art and challenges in high speed 
propulsion for both airplanes and space launchers. 
Specific lectures will address engine technology based on 
modified turbine cycles, pulsed detonation engines, rocket 
engines, ram and scram jets. In the light of existing 
environmental concerns, dedicated sessions will examine 
chemical pollution and noise generation. A thorough 
analysis on the requirements to implement a complete 
hydrogen technology will be examined. The program will be 
completed with a discussion on the experience acquired 
over the past years in developing advanced demonstrators 
in USA, Europe and Asia. The Directors of this VKI/RTO 
Lecture Series are Prof. G. Paniagua of the von Karman 
Institute and Dr. J. Steelant of the European Space Agency 
ESTEC.
