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

Get Started

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.

• Advanced materials components
• Body components manufacturing
• CFRP powertrain parts
• Metal Matrix Composites
• Advanced Computer simulation
• Hybrid materials components
• Titanium and Super Alloys
• Advanced Virtual Reality

R&D in Aerospace, Energy and Advanced Materials 

• Advanced materials engineering (lightweight alloys, composites, coatings)
• Additive & subtractive process integration
• AI-assisted system design and simulation
• Energy harvesting and management for embedded systems
• Laser-based technologies for orbital and terrestrial use
• Embedded intelligence and real-time control logi
• Multiphysics and digital twin modelling (FEM, CAE, LCA/LCE)
• Systems pre-validation and prototype iteration 

Extreme testing

Our internal facilities allow testing under vibration, thermal gradient, and vacuum.

Systems are validated for resilience, usability, and AI control feedback under simulated mission profiles — from desert to orbit.

• Tests in extreme conditions
• State of the art fully instrumented laboratory vehicles
