Question: An ideal ramjet is operated at 50,000 ft and Mach 3. The diffuser and nozzle are assembled to be isentropic, and the combustion is to be modeled as an ideal heat interaction at constant Mach number with constant total pressure. The cross-sectional area and Mach number for certain engine stations are given. The total temperature leaving the combustor Tr4 is 4000°R.
a) Determine the mass flow rate of air through the engine (lbm/s)
b) Complete the table with flow areas, static pressures, static temperatures, and velocities.
c) Find the thrust (magnitude and direction) of the diffuser, combustor, and nozzle.
d) Find the thrust of the ramjet
