In the aeronautical engineering industry, complexity and constant evolutions in the on-board information systems require a constant updating capacity. Being an actor in this market requires multiple and complementary skills.

The Grupo SII has more than 10 years of experience in the research and development of aeronautical engineering. Our skills in this field have allowed us to capitalize an important industrial know-how in many aeronautical disciplines in which we offer value-added solutions:

Embedded Systems

We have a team of engineers that responds to a wide range of skills, covering all fields of application across industrial sectors as automotive, mobility, space engineering and aeronautics throughout the ‘V’ cycle.


We are a benchmark in conducting safety and reliability studies of embedded systems, offering support services to our customers in the aeronautical sector (manufacturers or fuselage suppliers) in their certification activities.


We stand out for our ability to provide design services in the field of industrial engineering.

Thanks to this, our customers in the aeronautical sector receive comprehensive, comprehensive and comprehensive solutions.


We accompany aircraft manufacturers and their suppliers in the initial stages of development, through simulations that cover flight control, autopilot and navigation systems, as well as image systems by infrared, communication platforms and modular avionics.


Generation of work instructions (DELMIA), optimization and control of workflows (SAP), as well as planning and design of new lines or manufacturing cells, or development of new templates or tools.

Software Engineering

We offer a great variety of IT applications for MS Office and Catia V5, tailored to the needs of the client and based on BASIC and C # programming languages.

Structural Analysis

We carry out FEM calculations, analysis of composites, static and dynamic calculations, analysis of fatigue tolerance, damage and optimization of weight.

Development and systems integration

We work with the most common CAD development tools on the market such as CATIA, FiberSIM, CCD, PTC, UG or SolidWorks. We have the support of experts in the field of electrical systems, oxygen management, wastewater and air conditioning.

Validation and Ebitda

Specification services, qualification strategies and planning of tests and execution and the writing of reports and technical documentation .
