The jet stream exits a rocket motor at M=2.8 and at
ambient pressure, and strikes a two-dimensional
wedge with a total wedge angle of 40 deg as shown
in the figure.
1. sketch the initial (incident) wave pattern that
results from the jet stream striking the wedge,
2. show the additional wave pattern formed by
the interaction of the initial wave system with
the free boundary,
3. mark the flow direction in the region following
each wave form and show what happens to the
free boundary,
4. compute the Mach number and direction of the
flow after the air jet passes through each
system of waves,
5. attempt to sketch a pressure-deflection
diagram
