The first Symposium Transsonicum took pl.ace in Aachen thirteen years
ago during a period of decreasing governmental. and industrial. support
for transonic flow research. Since then, there has been a strong
revival. in interest in transonic flow research so that the number of
partici- pants at the second symposium remained about the same as at the
first even in spite of tight financial. means and Limited governmental.
support. During both meetings the number of participants reached the
upper Limit of the number desirabl.e for such a symposium. Participants
came from aU over the worl.d and there was a weU bal.anced distribution
of participants from aU countries interested in transonic flow research.
The discussions - mostLy conducted in EngLish - were stimul.ating and
there was a great deal. of interest in the l.ectures as was shown by the
good attendance even during the l.ast session on Saturday morning.
