In the case of ball mills, all internal wearing parts will pass through the manhole, whereas in the case of open end rod mills they will pass through the discharge trunnion opening. When lining the shell, start with the odd shaped pieces around the manhole opening if …
The reaction control thrusters, often located near the missile center of gravity or sometimes at the aft end, fire perpendicularly into the oncoming free stream. The resulting aerodynamic interaction effect creates a pressure disturbance on the surface of the missile that can be a large percentage of the nominal vacuum thrust
