Question

At launch, the space shuttle main engine (SSME) has 1030 lbm/s gas leaving the combustion chamber at Pt 3000 psia ani Tt 7350 R. The exit area of the SSME's nozzle is 77 times the throat area. If the flow through the nozzle is considered to reversible and adiabatic (isentropic) with Rgc 3800 ft s.°R ani γ= 1.25, find the area of the nozzle throat (in2) and the exit Mad number. Hint: Use the MFP to get the throat area. 3.11
