Design Engineer for Additively Manufactured Pressurized Aluminum Tank for Space Applications
TASKS
Develop a flight-representative design for a pressurized aluminum tank optimized for metal additive manufacturing and suitable for space applications .
The scope includes design, analysis, manufacturability optimization and test planning .
Provide end-to-end engineering support for a space-grade pressure vessel designed for additive manufacturing, including:
~ Review and refine system-level requirements, including:
# Operating pressure and proof/burst margins# Fluid type (e.g. inert gas, propellant, cryogenic if applicable)# Temperature range# Mission profile (cycles, duration, environment)# Interfaces (valves, mounting, feed lines)
~ Define applicable safety factors and failure criteria (NASA STD, ECSS, etc.)
~ Develop initial tank architectures, including:
# Geometry (cylindrical, spherical ends, domes)# Wall thickness and reinforcement strategy# Integrated features (ports, flanges, bosses)
~ Characterization of the critical manufacturing parameters for the 3D printing like:
# Deposition rate (mm/s)# Velocity# Thermal dissipation
~ Trade-off analysis:
# Mass vs strength# Manufacturability vs performance# Conventional vs AM-specific geometries
~ Optimize design for:
# Selected AM process (e.g. WAAM, DED, LPBF if applicable)# Build orientation and support minimization# Residual stress mitigation# Distortion control
~ Define:
# Material (e.g. AlSi10Mg, 6061/5083 variants if feasible)# Heat treatment strategy# Surface finishing requirements
~ Perform detailed analyses:
# Pressure vessel stress analysis (static and dynamic simulations)# Fatigue life estimation (if cyclic loading)# Fracture mechanics assessment# Thermal gradients and effects (if relevant)
~ Conduct:
# Failure Modes and Effects Analysis (FMEA)# Leak-before-burst assessment# Identification of critical failure points (ports, weld-equivalents, layer interfaces)
~ Define manufacturing approach:
# Recommended xpzdshu AM technology (WAAM / DED / EBAM)# Build parameters (high-level)
~ Identify post-processing steps:
# Heat treatment# Machining# Non-destructive inspection (CT, ultrasound, dye penetrant)
~ Develop a test program including:
# Proof pressure test# Burst test# Leak testing (helium mass spec or equivalent)# Structural validation
REQUIRED QUALIFICATIONS
