We help hardware, electronics, and subsystem teams mature designs into qualification-ready products.

By integrating thermal and structural capabilities under a unified systems view, EulerX ensures every design decision anticipates real test conditions.

From inserts and fixture definition to TIM strategies, thermal straps, and heat pipe implementation, we bring your hardware to test readiness for qualification and review.

Deliverables / Outcomes

  • Integrated thermo-structural design
  • FEA structural analysis
  • Environmental test planning and readiness support
  • I/F definitions — Inserts, TIMs, Straps, and Heat Pipes
  • Reviewer-ready reports

From Heritage to NewSpace — Program Support

Bringing large-mission experience into fast, commercial development cycles.

We bring the lessons of large satellite programs to fast-moving NewSpace missions.

With two decades of end-to-end experience — from concept to AIT and LEOP — EulerX helps teams plan qualification, navigate reviews, and prepare for test campaigns with confidence.

Deliverables / Outcomes

  • Qualification & verification strategy (ECSS / NASA aligned)
  • Review & test readiness support (PDR / CDR)
  • Team mentoring and knowledge transfer
  • Technical proposals and bid support
  • Campaign preparation (AIT / VIBE / TVAC)

In their words

Thanks to your support, we made rapid progress toward the CDR of our GEO satellite platform

Why I Built EulerX

Lucas Cubau — Founder & Lead Engineer, EulerX Aerospace
After 20 years designing and qualifying satellites under the rigorous standards of international space agencies, I saw NewSpace teams moving fast — but hitting the same avoidable traps: late discoveries, rushed reviews, costly surprises.
I founded EulerX to bridge that gap — giving fast-moving teams access to flight-proven engineering exactly when it matters most.

I spent two decades leading thermal development for GEO and LEO spacecraft, learning how discipline, systems thinking, and accountability make or break a mission.

When NewSpace gained momentum, I began collaborating with startups that were redefining what was possible — agile, fast, and bold. But I also saw how the lack of specialized expertise and structured engineering slowed progress and increased risk.

Thermal and mechanical challenges were often found too late, reviews slipped, and qualification campaigns faced costly surprises.

That’s why I created EulerX Aerospace — to combine the rigor of heritage space programs with the agility today’s missions demand.

Our mission is simple: help teams deliver flight-ready performance with confidence and clarity — from concept to orbit.
