Marco Pietropaoli, CEO of ToffeeX, discusses how ToffeeX is revolutionizing aerospace engineering design by enhancing combustion efficiency, optimizing coolant systems, and advancing battery thermal management. By reducing R&D design cycles to mere weeks, ToffeeX is advancing electrification, NetZero, and hydrogen applications across the aerospace sector. Here’s a closer look at the conversation.
Engineering design enters a new era of engineering design optimization
The world of engineering design is undergoing a significant shift. Forty years ago, we shifted from pencil and paper to digital tools like CAD. Now, we’re experiencing another transformation.
Two driving forces are behind this transformation: the need for sophisticated designs to tackle major challenges like decarbonization, electrification, and hydrogen applications and the rise of additive manufacturing, which is reshaping how components are designed and built for aerospace.
However, Marco highlights a significant challenge:
We can’t afford to spend decades iterating through slow and expensive trial-and-error R&D. We need tools to quickly bring optimal designs to market.
Shifting creativity from human intuition to machine-driven optimization
ToffeeX’s advanced generative design software shifts part of the design process from human intuition to machine-guided design. This is crucial for aerospace engineering design optimization, where complex designs must be developed quickly and effectively. Marco elaborates,
It’s not just about reducing design cycles—it’s about reaching solutions that human intuition alone couldn’t achieve. Our designs follow the laws of physics, often resembling natural structures shaped by millions of years of evolution.

By letting the software guide the design, ToffeeX rapidly explores complex, optimized solutions that align with manufacturing constraints and performance requirements. Marco emphasizes that ToffeeX isn’t meant to replace engineers but to enhance their capabilities. It integrates seamlessly into existing workflows to speed up design cycles and deliver efficient, manufacturable solutions.
Accelerating R&D cycles from years to weeks
One of the most significant benefits ToffeeX provides is reducing R&D design cycles from years to weeks, a crucial factor for aerospace design optimization. Marco shares,
We’re reducing R&D iterations by up 70%-80-100% and more, turning multi-year projects into weeks-long sprints. This makes go-to-market timelines more meaningful and gives aerospace companies a competitive edge.
This acceleration allows quicker product launches, pushing the boundaries of what’s possible in aerospace. With ToffeeX, engineers achieve designs that perform better and are also manufacturable, enabling groundbreaking innovation that was previously unattainable.
Real-world impact: ToffeeX in aerospace design optimization
ToffeeX has already made waves in the aerospace industry. Marco shares an impactful example:
ToffeeX can reduce the volume of a heat exchanger by up to 70%. You now have 70% more space to allocate to other components or to reduce weight. It’s a transformative change for the aerospace industry.
Beyond heat exchangers, ToffeeX also enhances thermal management in battery systems, which is vital for drones and other aircraft. The software reduces energy requirements for coolant flow and ensures uniform temperature distribution, resulting in longer-lasting and more reliable batteries. This is a key advantage for drones, where every gram of weight and minute of power count.

The future vision: ToffeeX as a core tool for aerospace engineers
Marco sees ToffeeX as a fundamental tool for engineers, especially in aerospace.
ToffeeX will accelerate energy transition and push the boundaries of aerospace engineering design.
ToffeeX integrates seamlessly into existing workflows, augmenting traditional CAD and simulation tools. It complements engineers’ work without disrupting their processes, making adoption more accessible and results more impactful.
