    Rocket thrust equation in under-expanded nozzle

    Hello, so the thrust equation goes like: F = (m dot)*v_e + A_e*(p_e - p_a), where F ... thrust [N] m dot ... mass flow rate [kg/s] v_e ... velocity of exhaust [m/s] A_e ... area of the exit nozzle plane [m2] p_e ... pressure of the exhaust at the exit of the nozzle [Pa(a)] p_a ... ambient...
