A solid rocket using 20% aluminum in the propellant is found to produce 37% of particulate
material by mass. Calculate the matched specific impulse of the rocket and compare it to what
it would be for the same Tc=3300K, but with no particles. Consider the following data: =1.17,
PePc=0.01, molecular weight =18gmol, specific heat of particulate material =1260Jkg-
K . How do the results compare with the linear approximation given in the class?
A solid rocket using 2 0 % aluminum in the
