Consider a 3 meter long solid motor with a cylindrical grain configuration using PU/AP/AL propellant. Before firing, the internal diameter is .25 meters and the maximum useable propellant diameter is 2 meters. a) Assuming an average burn rate, what is the internal diameter (in meters) after 30 seconds of firing? b) How long will this motor burn? c) What is the minimum & maximum thrust of this motor? d) Write an equation of the thrust as a function of web thickness
