“…Experimental observations (16,18,19,20) indicate that dust angle of attack and velocity strongly influence the erosion rate for a given combination of dust and target material. Other parameters such as particle size and shape, and dust concentration may have a lesser effect, if any, on the results.…”

A measurement 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 airplay in surge avoidance are 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 were 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.

“…The computed and measured stage characteristics are given in Table 2 To estimate the inlet relative fluid angle, and thus angle of attack to be used in equation 18, a typical velocity triangle at the inlet was constructed (Figure 8). Equation 19 was used to estimate the inlet fluid angle.…”
