Words from the Editor

Dear Colleague,

Welcome to a new edition of our newsletter, just a couple of days after Arianespace 100th Ariane 5 launch (VA243)!

The Ariane 5 launcher has, with his different variants, a long history, since its first launch in 1996: recently many other launchers have been deployed and there is currently an healthy competition in the segment of space launchers, for the heavy-lift market  in particular.


The Aerospace Europe newsletter’s primary objective is to bring to your attention

  1. Conferences that are of interest to our community
  2. Contents of the latest issues of scientific journals edited in Europe
  3. Relevant patents from the European Patent Office.

Occasionally, job offers and public policy issues will be posted (like for this newsletter, please see below).

If you hear of outstanding breakthroughs from other groups or have one from your own lab, do not fail to inform us at the special email address This email address is being protected from spambots. You need JavaScript enabled to view it. and we'll highlight them in the forthcoming issue.

This issue features five main sections:

  1. Public Policy Announcement
  2. News from Eucass
  3. Announcement of conferences from Aerospace Europe societies and the Pegasus network
  4. The usual tables of contents of European aerospace journals ordered by disciplines in order to facilitate access to material of interest to you
  5. The section "Patents of Interest" will look at a few patents of interest published in the last 6 months on a broad array of topics

Public Policy Announcement

After the FP7 and the H2020 research and innovation programs, the Commission is making preparations for their succesor, Horizon Europe with 100 billion € funding.

Some have looked closely to the Commission proposal and made some estimates, noting that the proposed budget falls short of the 160 billion € that are supposedly needed to adequately fund research and innovation in the coming years with all the new challenges of a changing world.

Our colleagues of the Initiative for Science in Europe and Euroscience wrote on a dedicated website:

...we believe that it falls short of the effort required of Europe to face the growing geopolitical challenges as well as the very high level of competition now set notably by Asian countries: gross domestic spending on R&D in the EU as percentage of GDP, which is below 2% and lags behind Korea (4.2%), Taiwan (3.3%), Japan (3.1%), USA (2.8%), China (2.1%, and constantly rising). There is a serious danger that the situation will force many promising young scientists to leave Europe, and that Europe will become less attractive for foreign scientists...

...We urge the European Parliament, the Council of Ministers and the European Commission to create the needed step change in budgetary commitment for Research and Innovation, by moving from the current 100 billion € target proposed for the next 7-year Financial Framework period to 160 billion €.

The method chosen to transmit these and similar worries to the Commission is to sign a petition

We encourage our readers to visit the links above and to sign the relevant petition if they share these views. 

 


News from Eucass

Please stay on alert: the call for papers of the July 2019 conference will be sent to you very soon.


News from Aerospace Europe partner societies

To always fine the latest news for the events organized by the Aerospace Europe (ae in short) members, do not forget to visit the ae website.

Ercoftac

Ercoftac is organizing a High-Fidelity Industrial LES/DNS Symposium "Paving the Way for Accurate CFD", a 3 days event in Brussels (see venue here) the 14-16 November. Both Eucass and Euroturbo partner with Ercoftac in the symposium preparation and contribute sessions.

HiFiLeD Symposium objectives: 

With the advent of large scale computing power and facilities, a new area of turbulence research is opening with the ability to perform reliable high-fidelity large-eddy simulations (LES) and direct numerical simulations (DNS) for industrial relevant flow configurations.

This availability is opening exciting new avenues towards understanding and modeling turbulence and transition by:

  • Direct generation of HiFiLeD to fully predict complex flows, by capturing most or all of the relevant turbulent scales and interactions
  • Analyzing in depth the underlying physics, supported in particular by new technologies of Machine Learning
  • Confronting available turbulence and transition models, identifying their deficiencies, improving the range of validity of current models and generating new ones.

Event Flyer available here.

Patents of Interest

An interesting, non paywalled, summary report about Industrial Innovation: Aerospace & Defence Manufacturers can be found at the patsnap website. The summary report, while relative to the 2013-2015 period, can give some interesting insights to the evolution of patents applications and the main field of research. 

While this report is more biased towards the USPTO, identified some trends that should be the same across the world, like certain interest in the G01S sub-classification (radio-direction findings). 

Therefore, the following patents have been selected from the EPO database using the following criteria: "PUA12 >= 20180101 and IPC=G01S"  and selecting a few interesting patents in our field. In this case, this means all patents whose A1/A2 documents both have been published after January 1, 2018. Since patents can be filed towards different organizations, sometimes the data available in the EPO database (the version available for free online) is not the most complete. In that case an external link is used. 

 


How to browse the EPO patent list

There are different tools online to browse/search patents, for example google and the wipo. Here we will be using the EPO Patent information services for experts, from this address. It is possible to browse patents based on many parameters, inventor name, applicant/proprietor (usually a company), application date, etc. etc. In the future we will consider patents that have published their A1/A2 documents since the date of the last newsletter.

The definition of A1 and A2 are available here.

  • Basically when a European patent application is published together with the search report done by the agency, it is known as an A1 publication. When this application is published without the search report, it is an A2 document.
  • The search report is then published later as an A3 document.
  • When the patent is granted, it is published as a B document.

News from Aerospace Europe partner societies

To always fine the latest news for the events organized by the Aerospace Europe (ae in short) members, do not forget to visit the ae website.

Royal Aeronautical Society

The Royal Aeronautical Society is organizing a 3 days event in Bristol (see venue here) the 24-26 July.

This Future of Aerodynamics conference will provide a forum for the presentation and discussion of aspects of the advancement of the aerodynamic disciplines and their application in a civil and military context through current research, nearer term conception and longer term design and operations.

The 2018 Royal Aeronautical Society biennial Applied Aerodynamics Research Conference will also mark the 100th anniversary of the formation of the RAF.

Program available here.



EUROMECH Logo

EUROMECH is organizing its Colloquium 598 on Coherent structures in wall-bounded turbulence: new directions in a classic problem that will be held the 29-31 August at the Imperial College - London, UK.

Coherent structures have been an hot topic of investigation in turbulent research for years.

Recently, there has been a growing body of evidence that the dynamics of the newly discovered coherent structures at high Reynolds numbers may well be approached with suitable extensions of the theoretical tools used for transition and for low-Reynolds-number turbulence. This emerging topic provides many important new opportunities for the development of novel low-dimensional descriptions of high Reynolds number turbulent flows, while establishing an integrated view on transition and turbulence in a wide range of Reynolds numbers.

The scope of the proposed Euromech colloquium is to explore this topic by bringing together a group of experts in transition and turbulence of wall-bounded shear flows. The latest results on both transition and turbulence will be presented with the particular aim to address important current challenges and future directions in theory, computation and experiment. 


EUROMECH Logo

EUROMECH is organizing its 12th European Fluid Mechanics Conference (EFMC) that will be held the 9-13 September 2018 at TU Wien, Vienna, Austria.

EFMC is organized biennially under the auspices of EUROMECH and covers all fields of fluid mechanics. Since the inaugural meeting in Cambridge 1991 the EFMC has evolved to the main fluid mechanics conference in Europe. It provides the opportunity to meet and discuss with the leading scientists in the field.

We are proud to host this important event in Vienna in 2018 and invite you to be become part of it. The organization team is working hard to make the conference successful and to make your participation a great experience.

Patents of Interest

 

The following patents have been selected from the EPO database using the following criteria: "PUA12 >= 20180101" and selecting a few interesting patents in our field. In this case, this means all patents whose A1/A2 documents both have been published after January 1, 2018. Since patents can be filed towards different organizations, sometimes the data available in the EPO database (the version available for free online) is not the most complete. In that case an external link is used. 


How to browse the EPO patent list

There are different tools online to browse/search patents, for example google and the wipo. Here we will be using the EPO Patent information services for experts, from this address. It is possible to browse patents based on many parameters, inventor name, applicant/proprietor (usually a company), application date, etc. etc. In the future we will consider patents that have published their A1/A2 documents since the date of the last newsletter.

The definition of A1 and A2 are available here.

  • Basically when a European patent application is published together with the search report done by the agency, it is known as an A1 publication. When this application is published without the search report, it is an A2 document.
  • The search report is then published later as an A3 document.
  • When the patent is granted, it is published as a B document.

Ercoftac Logo
EUCASS Logo
Euroturbo Logo

ERCOFTAC is preparing an LES/DNS conference with support from EUCASS and EUROTURBO, the HiFiLeD symposium.

Supported by the EU H2020 TILDA project, it will take place in Brussels, 14 to 16 November 2018.


With the advent and growing availability of large scale computing power and facilities, a new area of turbulence research is opening with the ability to perform reliable high-fidelity large-eddy simulations (LES) and direct numerical simulations (DNS) for industrial relevant flow configurations. 

This availability is opening exciting new avenues towards understanding and modeling turbulence and transition by:

  1. Direct generation of HiFiLeD to fully predict complex flows, by capturing most or all of the relevant turbulent scales and interactions
  2. Analyzing in depth the underlying physics, supported in particular by new technologies of Machine Learning 
  3. Confronting available turbulence and transition models, identifying their deficiencies, improving the range of validity of current models and generate new ones.

This novel approach of High-Fidelity LES/DNS data has attracted many researchers in recent years, stimulated by other emerging areas, as Big Data, Artificial Intelligence (AI) and Machine Learning (ML), providing new efficient methodologies for interrogating and investigating very large data sets.

These topics of turbulence research are the main focus of thisf new HiFiLeD Symposium.

 One resource has been recently brought to our attention: https://www.academicgates.com.

It collects academic offers from all over the world and on various fields, with a few thousands in Engineering alone.

It may be of help for some of our readers so we are happy to mention it here and in our website.

Words From The Editor

Dear Colleague,

  The last newsletter relayed the exciting news from  easyJet about their plan to introduce within the next decade an all-electric airplane for hauls up to 335 miles (i.e. from London to Paris). 

  Similar activities of other actors were recalled. We now have fresh news of another Airbus project on the future of flight, specifically the Vahana project. This project concerns a fully electric and autonomous VTOL aircraft, to improve urban mobility. The prototype of this aircraft has just been moved from the production site to a testing site in Oregon, where test flights are planned within the end of the year.

  The ambitious target is to have by 2020 a demonstrator fully certified for use with approved landing/departing helipads/spots and ready for production.

  It is not a "flying car", but another mean of transportation, completely electric, self-piloted (an autonomous vehicle), capable to detecting obstacles and other aircrafts by itself, and carrying 1 person or equivalent cargo. 

  In related news, Uber, the company better known for their drive hailing services and for their quest for autonomous vehicles, has recently released a 98 pages document on their vision of future of transport via autonomous VTOL vehicles.  

  Research on autonomous vehicles, more specifically on sensors, methods, systems and AIs is booming in these years (see this interesting article on IPWatchDog of last year, with a more recent evaluation by Statista this summer), with even Apple releasing days ago a paper on the ArXiv platform  on their researches on the topic (we remember that ArXiv is one of precursors of the open-access journals that we find available today).

Therefore, for the section "Patents of interest", we will look at some recent patents relative to the research on autonomous vehicles.

History

Brought to our attention by

Professor Bagdat Suimenbayev,

Kazakh National Research Technical University

Almaty, Kazakhstan

 

On October 4, 1957 the first artificial Earth satellite (AES) was launched from the Baikonur cosmodrome (see this link for the October 5, 1957 edition of the the New York Times).  

It made 1,440 revolutions around the Earth (about 60 million kilometers).

This date opened the era of space in the history of mankind.

The satellite represented a full-sphere with a diameter of 58 centimeters, weighing 83.6 kilograms. It was equipped with four 2.4-meter and 2.9-meter-long antennas for signal transmission from transmitters operating on batteries. Today, satellites perform many tasks at the service of numerous nations.

More than 140 countries have their own satellites, most of which were launched from the Baikonur cosmodrome.

Sixty years on, the EUCASS community wishes to celebrate and thank the pioneers that accomplished this outstanding exploit. They appreciate in full the history of the launch of the first artificial Earth satellite from the legendary Baikonur cosmodrome.

They call for further joint exploration of the universe in our common interests and congratulate all people of Earth on this epochal event, the beginning of the space era.

 


Patents of Interest

 

The following patents have been selected from the EPO database using the following criteria: "WORD 'autonomous'  AND PUA12 >= 20160101". In this case, this means all patents whose A1/A2 documents both have been published after January 1, 2016 and contain the keyword(s) aforementioned. Since patents can be filed towards different organizations, sometimes the data available in the EPO database (the version available for free online) is not the most complete. In that case an external link is used. 


How to browse the EPO patent list

There are different tools online to browse/search patents, for example google and the wipo. Here we will be using the EPO Patent information services for experts, from this address. It is possible to browse patents based on many parameters, inventor name, applicant/proprietor (usually a company), application date, etc. etc. In the future we will consider patents that have published their A1/A2 documents since the date of the last newsletter.

The definition of A1 and A2 are available here.

  • Basically when a European patent application is published together with the search report done by the agency, it is known as an A1 publication. When this application is published without the search report, it is an A2 document.
  • The search report is then published later as an A3 document.
  • When the patent is granted, it is published as a B document.
