MIL Standards

Environmental Engineering Considerations and Laboratory Tests MIL-STD-810H: Shock, vibration (sine/PSD), thermal extremes, humidity, altitude, sand/dust, etc. Why it matters: drives your thermo-structural design, material choices, wedge-locks/TIMs (thermal interface materials), and test procedure.

Electromagnetic Interference Control MIL-STD-461G: Radiated/conducted emissions & susceptibility. Why it matters: influences enclosure design, grounding/EMI gaskets, connector bonding, and layout to pass EMC tests.

Environmental Conditions and Test Procedures for Airborne Equipment (RTCA DO-160G/H): Airborne-specific vibration, temperature, power input, lightning/ESD, fluids. Why it matters: guides avionics packaging and qualification when the LRU goes on aircraft.

I’ve started digging into the key standards for this role and I’m confident I can design to them. In prior roles I’ve successfully come up to speed on unfamiliar standards and applied them rigorously—for example, using ASTM F2052 while designing an MRI patient bed for a high magnetic-field environment, and applying relevant CAN/CSA high-voltage standards when developing a high-voltage test fixture. Translating requirements into clear design and test criteria is one of my strengths, so I don’t anticipate any issue meeting the military/aerospace specs here.

FEA Techniques 

Beyond static and transient ANSYS work, I’m comfortable with

• Modal analysis → natural frequencies & mode shapes to avoid resonance; damping assumptions;
• Random vibration (PSD) response → base-excited PSD per MIL-STD-810 profiles
• Shock analysis → half-sine/terminal peak sawtooth or SRS-based inputs; checking connectors, wedge locks, and CG/fastener margins.
• Steady-state & transient thermal → conduction paths, TIM effectiveness, heat-spreader/baseplate performance
• Contact & preload modeling → frictional contacts, bolt/wedge-lock pretension, gaskets; assessing joint slip and load path.
• Submodeling & mesh convergence → coarse global model + fine local submodel
