Material used to support the Turbomeca Arriel 2C2-CG engine is which type material?

• A. Type 4
• B. Type 7
• C. Type 2
• D. Type 5

Answer: (B)

Engine support components must withstand high mechanical loads, vibration, and thermal cycling during flight, start, and shutdown. The Turbomeca Arriel 2C2-CG installation specifies Type 7 as the material for the engine support because it provides the right balance of strength, fatigue resistance, and thermal stability needed for those demanding conditions, along with good compatibility with fasteners and coatings used in the installation. Other material types don’t meet these performance requirements as effectively, so they aren’t used for the engine support in this application.
