Interpretation of Gas Turbine Response Due to Dust Ingestion

Abstract

A measurements program currently underway at Arvin/Calspan Advanced Technology Center has been used in the evaluation of observed engine behavior during dust ingestion. The Pratt and Whitney TF33 turbofan and J57 turbojet were used in the investigation. Solid particle ingestion was found to erode the compressor blades and result in substantial performance deterioration. The engines were found to have increased susceptibility to surge at low power settings. The roles that anti-ice and intercompressor bleed air play in surge avoidance discussed. A discussion of the fuel controller behavior in a deteriorated engine and its effect during steady state engine operation is also presented. Experimental data obtained during testing was compared to a predictive capability developed to describe deteriorated engine response. The effects of tip clearance, blade profile, and secondary flows were taken into account. The results show good agreement with experimentally observed engine behavior.
