What is Landing Gear Structural Components?
π¬ Landing Gear Structural Components represents a complete system of precision titanium components engineered for Aerospace & Defense applications. Large-section forged struts, links, and beams with complex internal bores, trunnion pins, and lug attachments The system integrates 3 distinct component types manufactured through 3 specialized processes.
Key manufacturing processes for this system include 5-axis CNC roughing for landing gear geometry, Heat treatment (STA) for net-shape tolerance, Wire EDM contour profiling for net-shape tolerance, CMM per AS9102 for net-shape tolerance, Heat treatment (STA) with SPC sampling, each selected and qualified to meet component-specific requirements.
Engineering & Design Principles
Material: Ti-1023 (Ti-10V-2Fe-3Al) is the premier landing gear titanium alloy, offering tensile strength >1100MPa with fracture toughness >50MPa.m0.5 β directly replacing 300M steel at 40% weight saving.
Form: Large closed-die forging is mandatory to achieve the required grain flow orientation along principal stress axes. No alternative forming method achieves the needed mechanical properties.
Standards & Material Specifications
Standards: AMS 4984 / AMS 4986 Ti-1023, STA condition, 100% UT Class A + mechanical test per lot

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
