What is Landing Gear Structural Components?

πŸ›¬ 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

  • ⚠️ 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) 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.

4 Manufacturing Process & Services

Core Processes:

Closed-die forging on large press (>5000T)Solution + aging heat treatment5-axis CNC machining of bores and lugsSurface enhancement (shot peening)

Toll Processing Services:

Ultrasonic inspection (UT Class A)Magnetic particle inspection (MPI)Fatigue testing (S-N curve generation)Dimensional inspection (laser tracker)

Process Pitfalls:

  • ⚠️ Ti-1023 is sensitive to inclusions β€” 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
