A procedure for sizing propulsion system filter capacityA propulsion system filter has the function of protecting downstream components from propellant-borne particulate matter. A the same time, it must be designed with sufficient capacity to ensure that it will not clog during the life of the spacecraft. This capacity can be quantitatively calculated by means of the procedure described here. Previous work has presented limited data which suggest that filter clogging is a function of the number and size of ingested particles. Cleaning specifications for propusion system components are also normally given in terms of the number and size of particles removed by the flow of test fluid. It is proposed here that the filter capacity be given in terms of the number and size of particles, which in turn may be convected to an equivalent quantity of test dust.
