Unformatted text preview: The subsonic leg occurs right at choking onset. The supersonic leg occurs if p B < p (no shock inside duct). 5. Why do the waves reﬂect back into the jet rather than “escaping”? (1 student) The waves cannot propagate outside the jet because we have assumed the ﬂow outside the jet is still ( M = 0), or at least subsonic ( M < 1). Stationary shocks or waves are possible only if M ± 1. However, the waves in the exhaust jet of a supersonic aircraft will indeed undergo only a partial reﬂection, with part of each wave “excaping” from the jet into the surrounding supersonic ﬂow. We haven’t looked at this more complicated case. 6. No mud (6 students)...
