I’m Sergio Perez Fontana, an Aerospace Engineer, Manager, and Technologist with over 30 years of experience in Flight Sciences and Structures. My career spans many successful aircraft programs at Boeing, Gulfstream, Bombardier, Bell Helicopter, and Embraer, where I led cross-functional teams in driving innovations through process and design optimization. I’ve led the implementation of advanced methodologies integrating advanced aerospace and exponential technologies for aircraft and other high-performance products maximizing efficiency and effectiveness. I have also developed a deeper specialty in Generative Design and Structural Optimization. Since 2014, I’ve explored and applied topology optimization and AI-driven generative design techniques, leveraging various generative design tools to inspire better, more efficient designs. For example, I contributed to achieving significant weight reduction in thick aluminum plates used to support heavy monuments on the Boeing VC-25B New Air Force One Presidential Aircraft, achieving tangible benefits in structural performance and cost. Traditional design methods often yield heavy, costly parts with underutilized material after long design processes. Every structural component, regardless of the scale of the project or budget, can benefit from my proprietary AI-driven workflows to transform conventional designs into structures that are: - Stronger and lighter: Eliminating unnecessary mass while exceeding performance requirements. - Optimized for manufacturability: Custom-tailored for efficient, scalable production using subtractive or additive processes. - Cost-effective and ready for validation: Minimizing engineering effort and material usage while seamlessly integrating into certification and operational workflows. This approach delivers high-quality structural engineering solutions faster and at a lower cost. Whether you’re developing an advanced component for a Martian flying vehicle or a flying hydrofoil board over water, I bring deep aerospace expertise and advanced AI tools to help you overcome your design challenges.
