fficially recognised High Tech Innovative SME by Spanish Government

At D4S, engineering is the convergence point of advanced technologies applied to space systems, energy platforms, and intelligent materials.

From orbital laser targeting to LCA-modelling, we prototype tomorrow’s tools today.


All core activities are supported by our internal AI platform, TESLA–FEYNMAN, which co-pilots R&D, simulation and digital twin orchestration across domains.



D4S – Durante Space Tech is an officially recognised Spanish innovative SME, founded by Dr. Eng. Sergio Durante.

With over 30 years of experience as background, D4S operates at the convergence of aerospace, mobility, and high-performance engineering, delivering frontier technology and real-world impact.


What We Do

We generate and transform knowledge into advanced components, intelligent systems, and AI-powered platforms across multiple sectors.

Our capabilities span:

    •    Design and integration of complex subsystems

    •    Development of advanced materials and lightweight architectures

    •    Simulation-based engineering (FEM/CAE, LCA/LCE, digital twin)

    •    Prototyping and testing for orbital, automotive, and hybrid platforms

Automotive and Motorsport

Technologies developed in high-performance motorsport environments are transferred to mission-critical aerospace and energy applications.

This includes hybrid propulsion components, lubrication systems, and precision gearsets for extreme conditions.
