What is Missile & Rocket Motor Hardware?
🚀 Missile & Rocket Motor Hardware represents a complete system of precision titanium components engineered for Aerospace & Defense applications. Cylindrical/conical thin-wall casings, flanged rings, domed end closures with polar bosses and attachment lugs The system integrates 3 distinct component types manufactured through 3 specialized processes.
Key manufacturing processes for this system include 5-axis CNC roughing for missile hardware geometry, Heat treatment (STA) at 200W fiber laser, Wire EDM contour profiling at 200W fiber laser, CMM per AS9102 at 200W fiber laser, Heat treatment (STA) for net-shape tolerance, each selected and qualified to meet component-specific requirements.
Engineering & Design Principles
Material: Grade 5 (Ti-6Al-4V) offers the best balance of strength, toughness, and weldability for rocket motor cases. Higher strength beta alloys for ultra-high pressure applications.
Form: Ring forgings for case sections and flanges. Plate rolled and welded for large-diameter cases. Spin forming for domed closures.
Standards & Material Specifications
Standards: AMS 4928 Grade 5, annealed, 100% X-ray of welds + hydrostatic proof test to 1.5x MEOP

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

Manufacturing Process Flow
5-axis CNC milling centers provide simultaneous multi-axis interpolation for complex titanium components. The ability to tilt the tool relative to the
Closed-die forging of titanium uses shaped dies to compress heated billet into a net-shape or near-net-shape component. The process aligns grain flow
Electron beam welding of titanium in vacuum produces deep, narrow welds with minimal distortion. Single-pass welds up to 100 mm thickness without fill
