what is the maximum speed (umax) that the missile could achieve in level flight? (hint: (1) when thrust is equal to the drag, there is no acceleration which means maxi speed. we assumed no drag, so it means when maxi speed is reached, the thrust is 0. (2) at this point, air reaches its maximum temperature, and no fuel injection is needed.) b) what would the velocity be of the gas exiting the nozzle (i.e., ue) at this maximum operating flight speed? c) sketch (qualitatively) the ramjet cycles for both cases (u
