FAQ

Q1:What is a Variable Inlet Guide Vane (VIGV) Case?

A1:A Variable Inlet Guide Vane (VIGV) Case is a front-end structural component of an aero engine that incorporates adjustable guide vanes to control the angle and pressure of incoming airflow before it reaches the compressor. This mechanism helps improve engine efficiency, prevents compressor stall, and optimizes performance across varying flight conditions.

Q2. What materials are used to manufacture VIGV cases?

A2:VIGV cases are typically made from high-performance aerospace alloys such as Ti-6Al-4V and Inconel 718, ensuring excellent strength and thermal resistance. All materials are sourced from ASL-certified suppliers and comply with standards like AMS 4928 and AMS 5662, with full heat lot traceability and Mill Test Reports (MTRs).

Q3. How do you ensure the quality of each VIGV case?

A3:Our VIGV cases undergo a comprehensive quality assurance process, including:

• AS9102-compliant First Article Inspection (FAI)
• Full dimensional verification using CMM and CAD-based inspection
• Surface roughness checks (Ra ≤ 0.8μm)
• Dynamic balance and vibration testing (if applicable)
  All steps are performed under AS9100D and NADCAP certified processes with full traceability documentation retained for at least 10 years.
