🔧 Aerospace Ducting & Pneumatic Systems
Thin-wall tube/duct assemblies with formed bends, flanges, bellows, and branch connections
What is Aerospace Ducting & Pneumatic Systems?
🔧 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, 5-axis CNC roughing for engine component geometry, 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
- ⚠️ Ultra-high tensile and compressive stress during landing
- ⚠️ Stress corrosion cracking from runway de-icing chemicals
- ⚠️ Impact fatigue from repeated landing cycles
- ⚠️ Weight reduction for fuel economy
2 Material Selection Rationale
Ti-1023 (Ti-10V-2Fe-3Al) — Beta alloy, ultra-high strength >1100MPa, high fracture toughness
Ti-1023 (Ti-10V-2Fe-3Al) offers >1100MPa yield strength with high fracture toughness (>60 MPa·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 — 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:
- ⚠️ Ti-1023 is sensitive to inclusions — VAR double-melt mandatory for all landing gear stock
- ⚠️ Lug hole surface finish must be Ra<0.8um to prevent fatigue crack initiation under cyclic tension
