INSA is one of the main engineering schools in France because it graduates more
than seven percent of all the engineers graduated in France.
Since that date, I teach at the mechanical engineering department
focusing on modeling, simulation
and control of mechanical power transmission systems, especially for aerospace.
In parallel I have a research activity at the Clément Ader institute
which merges in Midi-Pyrénées all the activities
related to the mechanical domain and within this laboratory
I developed an activity that is related to embedded actuation systems and of course in Toulouse
embedded actuation systems means aerospace.
For me, the main issues for the aerospace industry
is to face some challenges
between incremental innovation
and major steps that make some ruptures.
So typically the problem
is to have a view at the global product,
which is to move persons from one side to another side,
being greener, safer and cheaper.
So today there is a big challenge in being able to design better
and faster systems which involve more
interactions between domains : mechanical engineering,
electrical engineering, informatics and so on.
So for our engineering challenges, LMS Amesim is interesting, because of
the structuration of the model
that has a high influence on the use of the model.
So we are able to structure model, to think about interfaces
and something that we can very trust in is the reliability of the
numerical solver.
That is sometimes forgotten be the users, they only want results
if we change the solver we change the results, for LMS Amesim we can be very
confident in the solver.
For the flight control design
we have many things that have changed the modeling and simulation process
due to the switch between technologies.
At first, we were mecanically signaled and hydraulically powered.
And finally it was a situation that was quite well established
for hydraulically power since early 60's
and for power, fly-by-wire, for electrically signaled since the early 80's
for commercial aircrafts.
So this has generated a step in signaling then made a step in powering
by more electrical aircraft when we have to provide power to the actuators
of the flight controls, by mean of electrical power.
And this generates to a very high change, which required the engineer
to have new approach, they can no more rely
on the process is a use for another technology
because we have some side effects that belong to a given technology.
For these new technologies of actuators especially considering powering
the interest of LMS Amesim, that was one of the first simulation tool to provide,
is that be able to combine different a physical domains
mechanics, electrics, electrotecnics, power electronics, hydraulics, thermal and so on.
So now we have to address a wider and wider domains
and as actuators involve mechanics, electro-technology sometime hydraulics
with the electro-hydrostatic actuators, we have to be able to investigate
a product which requires models in each domains.
Finally LMS Amesim is quite easy to use because we have very structured libraries
that enable addressing all these domains with
given interfaces, given parametrization
and that is well in phase with the demand.
