What is Aero Engine Compressor Blisks & Blades?

🌀 Aero Engine Compressor Blisks & Blades represents a complete system of precision titanium components engineered for Aerospace & Defense applications. Integral bladed-disk (blisk) with complex 3D aerofoil contours, thin trailing edges, platform and root attachment features The system integrates 4 distinct component types manufactured through 3 specialized processes.

Key manufacturing processes for this system include 5-axis CNC roughing for engine component geometry, Heat treatment (STA) with Class 6g gauge, Wire EDM contour profiling with Class 6g gauge, CMM per AS9102 with Class 6g gauge, Heat treatment (STA) with SPC sampling, each selected and qualified to meet component-specific requirements.

Engineering & Design Principles

Material: Ti-6242 (Ti-6Al-2Sn-4Zr-2Mo) is the industry standard for compressor blisks, offering high creep strength up to 520C and excellent low-cycle fatigue life. Replaces heavy Ni superalloys.

Form: Precision die forging of the blisk blank followed by 5-axis CNC milling of aerofoil profiles. Near-net forging reduces machining time by 60% vs billet machining.

Standards & Material Specifications

Standards: AMS 4919 Ti-6242, forged + solution-treated + aged, 100% FPI + CT scan of aerofoils
