5. Consider uniform, inviscid, supersonic flow exhausting from a rocket engine nozzle. For fixed back pressure p (i.e., the ambient pressure outside the nozzle), qualitatively draw the first few wave inter- actions downstream of the nozzle exit for the following exhaust-gas static pressures. Label boundary conditions, wave types, and local pressures (relative to p), and indicate flow streamlines. a) p = P(perfectly expanded nozzle) b) pp (overexpanded nozzle) c) p > Pb (underexpanded nozzle) 5.
