25.1707: EWIS System Separation Requirements Assessment
22-page summary covering damage assessment through compliance: heavy current cables, grounding, power separation, control cable separation, and arc damage simulation.
Arc Damage Modeling Tool (ADMT): Simplifying EWIS Failure Severity Assessment
Developed with the FAA to predict electrical arcing damage — quick-turnaround assessment of arc event severity, verified against physical testing, used in certification packages.
Addressing Fleet Management Needs With EWIS Risk Assessment Technologies
Lectromec’s turnkey process combining arc damage analysis, insulation degradation research, and risk assessment into a quantitative basis for fleet decisions.
Conference papers & presentations
Peer-presented research from the Aging Aircraft and Airworthiness & Sustainment conferences.
Examination of EWIS and Pressurized Hydraulic Lines
Dry arc tests on power feeder wires at set distances from pressurized tubes — how much energy it takes to rupture the target, feeding the ADMT model.
Arcing Damage at a Distance
Beyond direct-contact arcing: analysis and testing of electrical arc damage to components and wiring at a distance.
Arc Damage Modeling Tools Progress
Progress on the ADMT software: energy quantification and heat transfer models for damage to source wire, primary target, bundle, and objects at a distance.
Development of Arc Damage Modeling Tools
The plan that started the ADMT: why arcing failures matter as EWIS ages, and the mitigation landscape from arc-resistant constructions to AFCBs.
Evaluation of Wire Harnesses Recently Removed from F-16 Aircraft
With InterConnect Wiring: DelTest and Inherent Viscosity evaluation of 35 Nomex-covered MIL-W-81381 harnesses from an F-16 rewire, feeding a fleet risk assessment.
Evaluation of Risk on Orbiter
NESC-sponsored assessment of catastrophic-failure probability from an inadvertent RCS jet firing while the Shuttle Orbiter was mated to the ISS.
