Newsletter #29

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.
