International Astronautics Congress: four ESTACA students honoured

Tour

At the end of September, a delegation of 5th-year students attended the 67th International Aeronautics Congress (IAC) in Guadalajara, Mexico.

Among them, Pierre Foullon and Pierre Plévin, young entrepreneurs who developed aquaponics (1), presented a version of their project to colonize the planet Mars. Success was on the cards as they were supported by the French Aeronautical Astronautical Association (AAAF) and participated in the Student Competition. Perhaps a future avenue for development of the young start-up company Selfeden?

In another symposium, Aurore Piazza and Arthur Descamps presented the XCube concept to the international community. Developed by Arthur in 2015 at the occasion of his one-year internship at the NASA Ames research centre in California, XCube uses the CubeSat standard and adapts it to on-board experiments. Their team, comprised of 7 students from ESTACA’s Space option, used their 5th-year project to design and build the first demonstrator, before flying off to Moffetfield to present it to NASA. The prototype designed to be carried on the research centre’s drones, includes several features sought after in the field: imaging, flight environment analysis and analysis of air composition. Feedback from the international community was encouraging, especially regarding complete low-cost engineering problem solving.

The dynamic of ESTACA students at IAC since 2013 makes the French school one of the best represented at this major congress. This strengthens its strategic position within the sector and confirms its international reputation. Industrialists and organisations showed a keen interest in their careers, highlighting projects, practicality and knowledge of the industry.

The vehicle compartment air quality challenge

Point of view of Amine Mehel – teacher researcher at ESTACA

Air quality is a public health issue that directly affects the transport industry and forces it to innovate to offer cleaner, healthier transport. To measure air quality, ESTACA researchers are studying the concentration of particles and gas pollutants; the latter should not exceed a certain threshold, outside or inside, in order to limit harm caused to health and the environment.

The estimated health cost of the impact of poor air quality (stroke, respiratory problems, cancer, the foetus) is 68 to 97 billion Euros. Pollution also affects the environment and visibility (see China).
The framework law no. 96-1236 of 30 December 1996 on Air and Rational Energy Use aims at rationalising energy use and defining a public policy that includes air in urban development issues. Everyone has the right to breathe air that is not harmful to their health.

For industrialists, there is a dual goal: controlling emissions of gas and pollutants (factories, vehicles, exhausts, etc.) and secondly, analysing the dispersion of these pollutants and their infiltration into cars, planes, metro stations, train carriages, etc. Currently, a law exists on outdoor air quality, but not yet concerning indoor air quality. Studies have nevertheless shown that the air is more polluted and hence more harmful inside vehicles than outside (cumulative effect and concentration, to which can be added emissions from the materials themselves).

This air quality issue is the same for all types of transport. For automobiles, the pollutants seep into the passenger compartment through the air vents. In rail, braking in underground stations emits pollutants that enter the carriages and then the station. In planes, the air in the cabin originates from the turbojet compressor, and is charged with harmful oil droplets. There are various means of improving indoor air quality such as charcoal filters, that filter out some gas pollutants and the HEPA (High Efficiency Particulate Air) filter that can filter out particulate pollutants, with one exception: the particles are so fine that it is difficult to filter them out and this generates additional energy consumption which is, in turn, polluting.

ESTACA Lab' has leading-edge expertise in these issues and has been working closely with industry and institutions for many years. Here are some examples:

With Toyota Motor Europe to reduce pollutants at the source of the emission: the engine (for example work on Blowby gases, recovery of oil droplets using an oil remover so they are not burned). With start-up companies on the brake and brake particle capture devices.

With the ADEME (France’s Environment and Energy agency) we are working on ventilation or flow to deflect particles. For example, we are studying air intake situations – CAPTIVH project with the aim of preventing the infiltration and cumulative effect of pollutants in the passenger compartment.

With the SNCF CIM (engineering and materials centre), we are conducting a study into brake particles, simulating the dispersion of particles in interaction with the quays and in a sealed enclosure, and then analysing how they enter the carriage.

Two theses are currently being studied at ESTACA on these issues: one with IFSTTAR (French Institute for Transport Science and Technologies, Town Planning and Networks) on the experimental study of the dispersion of nanoparticles from exhausts and the other with the LEMTA (Laboratory of Energy and Theoretical and Applied Mechanics – Lorraine University) on a digital study of the interaction between nanoparticles, exhaust flows and vehicles, a thesis being conducted jointly with the University of Bamako in Mali. The students are also examining this issue via 3rd-year PIRATE projects (Project for initiation in applied research in mentored work).

While an initial step has been taken thanks to standards limiting the concentration of pollutants, there is still no standard regarding passenger compartment infiltration and hence indoor air quality (especially for the car and rail sectors). This is the second stage that ESTACA Lab is involved in with its partners, reflecting more generally on cleaner transport for the future.

China mission: new opportunities for academic exchange

Tour

The ESTACA management travelled to China in September to meet its partners and develop new exchanges. In Beijing, the delegation was received to celebrate the 15th anniversary of the partnership with Beihang or BUAA, the Beijing Aeronautics and Astronautics University, the leading Chinese research institution in aeronautics and aerospace. Student exchanges have been numerous and frequent between the two institutions and this cooperation should intensify following the visit: exchanges of professors, development of shared research work or joint tutorship of theses and setting up of a dual diploma are intended.

In Xi’an, ESTACA signed a new partnership with the Northwestern Polytechnical University (NPU) that will lead to exchanges between students and professors, joint research work (publications, colloquia, joint tutorship of theses, etc.) and eventually possibly also a dual diploma in composite materials, to mention the terms of a future partnership.

These three Chinese universities are highly favourable to developing relations with ESTACA and grants from the Scholarship Council will facilitate exchanges of students and doctoral students. They will be present at the international week organised by ESTACA at the Laval campus from 14 to 16 November to continue to discuss the development of privileged relations between the institutions.

ESTACA On The Salt: an electric dragster capable of reaching 400 kph

Tour

Around twenty ESTACA students have been working on this highly ambitious project since 2014: building an electric dragster capable of reaching 400 kph The team is planning on pulling off an achievement at the 2017 Speed Week in Bonneville, a mythical race taking place in north Utah, United States.

Every year over one week, almost 1 500 vehicles come to beat speed records in front of over 600 000 spectators. This will be the first time that a 100% electric French vehicle will be competing.

The vehicle and the project were presented on the ESTACA stand at the Motor Show.

ESTACA, FIRST INTERNATIONAL WEEK 2016

actu EIW2016 GBThe aim of this international event concerning the field of Green Transportation was to bring together ESTACA Partners in order to strengthen relationships and to initiate new collaborative research projects. It has also give the academic and administrative staff the opportunity to discuss subjects of common interest related to teaching and international partnerships. We received about 40 participants from companies and foreign universities from Canada, China, Greece, India, Italy, Morocco, The Netherlands, United Kingdom and United States of America.

The participants were able to assist to plenary session on “Challenges in Sustainable Mobility”, poster sessions, and scientific sessions on mechatronics, particle matters, materials and electrical/hybrid vehicle. ESTACA’s partner companies were also present as Flying Whales, SPARK Racing Technology, GRUAU, VALEO, EMC2 Cluster, CEMCAT and SNCF. A study abroad fair was also held in Laval and Paris-Saclay campus were some of our partners and future partner universities as HAN Arnhem University (The Netherlands), Notherwestern Polytechnical University (China), Manipal University (India), Heriot-Watt University (United Kingdom) and other were able to present to ESTACA’ students their different opportunities.

Researchers and teachers from ESTACA and partners were able to discuss potential research project, research internship and thesis under joint supervision. An exchange agreement for students, teachers and researchers was signed between ESTACA and AIAC (Académie Internationale Mohammed VI de l’Aviation Civile) in Morocco. ESTACA is also under discussion with Heriot-Watt University to sign an agreement for Master degree abroad and with Université International de Rabat (Morocco) for an exchange agreement.

This first ESTACA’s International Week was really intense and productive for ESTACA and its partners and we are looking forward for the next one in 2019.
