Mr. Duquette is a licensed professional engineer in multiple states with 20 years of experience in the machine tool, aerospace, construction / plumbing products, and medical device industries.  He began his career designing mechanical systems for the machine tool industry, then spent several years designing custom equipment, fixtures, and tooling to optimize manufacturing and quality processes for fluid transport systems in the aerospace industry. 

Later, he focused his efforts on product design and development in the flexible piping and tubing industries.  In this context, he studied lightning interaction with ground-based systems and developed a marketable lightning effects mitigating product.  More recently, he has designed and developed medical device implants and surgical instrumentation.

Working across several diverse industries has allowed Mr. Duquette to gain experience in various design, manufacturing, and regulatory environments.  His product development work consistently used 3D CAD programs with various projects requiring Mr. Duquette to evaluate components and systems utilizing finite element analysis for non-linear large deformation and contact analyses. Mr. Duquette has always had an end to end, hands on approach to product development and is consistently involved with the entire process from conception to design through testing and evaluation. 

Mr. Duquette is proficient in the analysis of mechanical systems and mechanical failures including water losses, ventilation systems, and gas-related events including fires and explosions. He has performed failure analysis on numerous systems including functionality, pressure, and leak testing on gas and water-based plumbing systems and appliances.

His areas of expertise include:

• Mechanical design and analysis
• Mechanical failures and forensics
• Lightning interaction with ground-based systems
• Fitting sealing technologies
• Failure analysis for water losses from appliances and plumbing failures
• Fuel gas systems – natural gas and LP gas (propane)
• Gas fed fires and explosions
• Gas and solid fuel appliance fires and soot
• Heating, Ventilation, Air Conditioning (HVAC) Systems
• Patent evaluation and analysis
• Computer Aided Design (CAD) solids modeling
• Finite Element Analysis (FEA)
