AN EXERCISE CONCERNING THE GREITZER SPAKOVSZKY 16 62X TEAM PROJECT Hypothesis proposed by our advisor, Murman: The thermodynamic loss in the flow through a blade row in a jet engine is less than 2% of the inlet dynamic pressure Objective: Go to Pratt& Whitney, obtain a blade row, measure the loss Success criterion: Establishing the loss through the blade row to an accuracy such that the hy pothesis can be assessed What does all this mean for the measurements we need? What would the final"slam dunk viewgraph"look like? We want to measure oss how do we do this? How well do we need to do it? 12AN EXERCISE CONCERNING THE GREITZER￾SPAKOVSZKY 16.62X TEAM PROJECT Hypothesis proposed by our advisor, Murman: The thermodynamic loss in the flow through a blade row in a jet engine is less than 2% of the inlet dynamic pressure Objective: Go to Pratt&Whitney, obtain a blade row, measure the loss Success criterion: Establishing the loss through the blade row to an accuracy such that the hypothesis can be assessed • What does all this mean for the measurements we need? – What would the final “slam dunk viewgraph” look like? • We want to measure “loss”. How do we do this? • How well do we need to do it? 12
