Abstract
One or more particle arrestors are mounted in a curved radial flow portion of a gas turbine starter annular flow passage, between a fluid inlet and a fluid outlet. The one or more arrestor rings block line of sight paths between the turbine wheel and the annular flow passage outlet. Thus, the one or more arrestor rings substantially inhibit relatively high energy particles from exiting the turbine housing, thus substantially inhibiting collateral damage to surrounding equipment and structure.
