The figure above shows a schematic of a gas turbine engine. Engines such as these provide thrust to commercial aircraft, and weight savings are very important. At the front on the engine, just after the air inlet, cold air is compressed by the front blades. Temperatures are usually below 100°C, and they undergo millions of revolutions during their service lifetime. The blades would typically be exposed to stress levels of around 500 MPa. (a) Use your materials reference sheet to choose a good material selection for the front blades. Explain your selection. Hint: which properties were most important? (100 words, approximately 2 sentences) (b) Name one manufacturing method that could be used to make the blade from the material that you selected in (a)? (c) What failure modes might you expect from this component? Explain your answer (100 words, approximately 2 sentences)
