Newsletter #19

World from the Editor

Dear [FIRST NAME%%Colleague],

We wish those of you that are already on vacation or about to leave a pleasant holiday. As for the others, we offer some reading with this Eucass Newsletter number 19.
The usual review of articles in journals of interest is presented hereunder, together with the section of recently published patents on the field of EVs.

Last, please take the time to read the preamble on public policy, a civic responsibility for all of us.

Public Policy Announcement

We research scientists and engineers bear a great responsibility in developing innovative concepts to keep Europe’s aerospace competitive. We hold its future in our hands. Our responsibility also covers the indispensable dialog with decision makers in achieving enlightened use of taxpayer’s money and its proper allotment between blue sky research and development.


Eucass is partner to the Initiative for Science in Europe (ISE), which “is an independent platform of European learned societies and scientific organizations whose aim is to promote mechanisms to support all fields of science at a European level, involve scientists in the design and implementation of European science policies, and to advocate strong independent scientific advice in European policy making.”


If you feel concerned, please contact me in order to discuss those issues and establish this constructive dialog with the European Parliament and Commission regarding aeronautics and space, and keeping contact with ISE.

In neighboring Belgium, the von Karman Institute, 10 years younger, celebrates as well its 60th Anniversary


A couple of our readers have sent us word of some interesting events about a 260KW electric engine from Siemens used for the maiden flight of an aerobatics single engine plane Extra 330LE, and of MOU  between Airbus and the aforementioned Siemens for the development of Hybrid Electric Propulsion Systems.


Meanwhile, the Solar Impulse 2 has just completed its world tour on the 26th of July without a drop of fuel, brilliantly marking the opening of a new era.

Recently Published Patents of Interest

Topic: Electric/Hybrid Engines for aviation

The following patents have been selected from the EPO database using the following criteria:  "WORD = hybrid engine AND WORD = aircraft AND PUA12 >= 20160101". In this case, this means all patents whose A1/A2 documents have been published after the first January 2016, with somewhere in the text "Hybrid Engine" and  "aircraft". 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.

The reason of this short overview of patent of iterest is made by the introduction to this newsletter. 

See below a selected few. 

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.
