Type 7 material is used to support which engine?

• A. Turbomeca Arriel 2C2 - CG engine
• B. Pratt & Whitney PT6
• C. GE CF6
• D. Rolls-Royce Trent

Answer: (A)

Materials chosen for engine support depend on the engine’s mounting design and operating environment. Type 7 material is specified for the Turbomeca Arriel 2C2 - CG engine because that engine’s mounting and support structure are designed to handle the particular loads, vibrations, and thermal conditions it experiences in service. The Arriel 2C2 CG setup requires a material with the right combination of strength, stiffness, and durability for those mounting points, so Type 7 is the designated choice in the maintenance data. The other engines—Pratt & Whitney PT6, GE CF6, and Rolls-Royce Trent—have different mounting configurations and load requirements, so they use different materials for their supports.
