Specialists in Numerical Simulation and Test Engineering

Aerostructure, engine, cabin, and systems: our teams have evolved with the main players in the aeronautical industry (aircraft manufacturers and OEM) and the space sector to develop ever more efficient solutions in terms of lightening and energy efficiency.


Along with equipment manufacturers and major aeronautical reports, over the course of several years, we have been acquiring solid knowledge of materials (composite, aluminium alloy, titanium) and the various manufacturing and assembly techniques (riveting, gluing) specific to the aeronautics and space sectors. Our knowledge of the standards in force and our expertise allow us to carry out studies ranging from the lightening of the structures of satellites to the simulation of the propagation of cracks in the frames of a fuselage (XFEM) through the analysis of the stresses on primary elements such as reinforcements between the fuselage and wing (crossbeam) or kerosene floors and tanks.


The propulsion system is a central element in the development of an aircraft. Our teams have the opportunity to respond to the problems of engine manufacturers on several aspects such as simulation of the propagation of cracks in turbine blades or crash simulations performed upstream of the famous Bird Strike. Our technical expertise also allows us to analyse the mechanical strength of the points of attachment between the pylon and the nacelle, but also to evaluate the pressures and thermal stresses within the turbines.


The development of the interior fittings of the cabin is very important because it contributes to the manufacturers' image. Our expertise in fluid mechanics and our advanced software solutions allow us to intervene on various issues related to passenger comfort such as the efficiency of air conditioning in the cabin. We can also perform analysis and optimisation of interior equipment such as seats, partitions, sanitary modules or storage boxes.


Surveillance, communication, navigation, the number of components and ancillary equipment in aeronautics are very important. Thanks to our knowledge of the standards set up by the Radio Technical Commission for Aeronautics (RTCA), we can help our customers to design and optimise these systems. This special expertise allows our teams to answer questions on vibration analysis, fatigue and emergency landing equipment maintenance, but also regarding electromagnetic compatibility.
