Abstract

Small radial inflow power generators are widely used by the U.S. Army for field operation. Experience has shown that the nozzle vanes are the most vulnerable component of engines in service. Degradation of vanes appears to result from erosion by ingested dust and by carbon from imperfect combustion, particularly with heavier fuels (e.g., Diesel #2). Teardown of affected engines shows that the nozzle vane trailing edge has been worn back to an extent that is in line with the calculated decrease of performance plotted in Figure 1. Replacement of the metal vanes by hot pressed silicon nitride solved the erosion problem as reported at the first meeting of this group in November 1973.
