Thin-wall tube/duct assemblies with formed bends, flanges, bellows, and branch connections
What is Aerospace Ducting & Pneumatic Systems?
π§ Aerospace Ducting & Pneumatic Systems represents a complete system of precision titanium components engineered for Aerospace & Defense applications. Thin-wall tube/duct assemblies with formed bends, flanges, bellows, and branch connections The system integrates 3 distinct component types manufactured through 3 specialized processes.
Key manufacturing processes for this system include 5-axis CNC roughing for pneumatic system 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) for net-shape tolerance, each selected and qualified to meet component-specific requirements.
Engineering & Design Principles
Material: Grade 9 (Ti-3Al-2.5V) has excellent formability and weldability, making it ideal for thin-wall ducting that requires bending and welding. Higher strength than CP-Ti.
Form: Seamless tube is the standard starting form for ducting. Can be CNC bent, end-formed, and welded into complex assemblies.
Standards & Material Specifications
Standards: AMS 4934 Grade 9 seamless tube, annealed, 100% X-ray of welds + helium leak test

1 Part Feature Analysis
Large-section forged struts, links, and beams with complex internal bores, trunnion pins, and lug attachments
- β οΈ Ultra-high tensile and compressive stress during landing
- β οΈ Stress corrosion cracking from runway de-icing chemicals
- β οΈ Impact fatigue from repeated landing cycles
- β οΈ Weight reduction for fuel economy
2 Material Selection Rationale
Ti-1023 (Ti-10V-2Fe-3Al) β Beta alloy, ultra-high strength >1100MPa, high fracture toughness
Ti-1023 (Ti-10V-2Fe-3Al) offers >1100MPa yield strength with high fracture toughness (>60 MPaΒ·m^1/2) for landing gear. Replaces high-strength steel at 40% weight saving. Beta-annealed for optimal SCC resistance.
3 Form Selection Rationale
Die Forging / Ring β for high-stress critical parts
Large press closed-die forging is mandatory for landing gear structural parts. Grain flow must follow the part contour for optimal fatigue life. Finish machining after heat treatment.

Process Pitfalls:
- β οΈ Ti-1023 is sensitive to inclusions β VAR double-melt mandatory for all landing gear stock
- β οΈ Lug hole surface finish must be Ra<0.8um to prevent fatigue crack initiation under cyclic tension
