Mechanical development of spatial equipment

Project overview

As part of the IND team (mechanical side of the manufacturer), we are in charge of the development of the architecture of a Pressure Regulation Unit (PRU). The goal is to generate a mechanical architecture from a list of components that respect the global dimensions and external stresses provided by the customer.

Client profile

We are working for the worldwide leader in power conditioning and distribution unit for satellites and one of the most important electronic providers for Ariane 5.

The product line covers the needs from observation microsatellites to the big geostationary communication satellites (Galilea, Globalstar, RASCAM, etc.).

Our client benefits from the first position in electronic product for flight equipment: avionic, plasma propulsion unit (PPU), DC/DC converter and other electrical products.


The challenge

The job site is split into two main domains: electricity and mechanical.
While in the first, the electric circuit is designed to respond to the client’s request from input to output.

Within the second domain, the physical aspect of the product is developed: implantation, mechanic, heat transfer, production, tests, etc.

Our solution

The first step of the development is to make implantation of the main components of the microchips used in the electrical design.Mechanical development of spatial equipment

As a result, the mechanical concept – structure, PCB, fixations, etc. – is developed,  regarding the global dimensions provided by the customer.

Mechanical development of spatial equipment

This development is made with the CAO software CATIA V5.
All the design have to be compliant with the customer’s request.
Finite element models are made of the equipment with ANSYS Mechanical APDL for thermal, mechanical and radiations analysis to ensure this result.
