Aerospace Europe Science News Bulletin - Issue #25

Edited by EUCASS under E-CAero contract

 

 

Words From The Editor

Dear Colleague,

  An interesting and exciting announcement about the future of civil aviation was made this summer. 

  The easyJet company, provided a press-release announcing their plan to introduce within the next decade an all electric airplane for hauls up to 335 miles (i.e. from London to Paris) with 180-220 passengers, and suggesting that all short-haul flights could be electric within the next 20 years. Multiple media outlets like theguardianCNN, or BBC covered this announcement and the company that would build the new plane, Wright Electric.

  Several others are know to work on electric planes like Boeing or Airbus, although on different time frames and passengers capacities and talks of easyJet interest on Wright Electric suraced last March. What is different is that now there is more confidence from easyJet that the proposed plane of Wright Electric could actually fly, while the original March rumors were met with skepticism from Industry experts (i.e. see article from Sasha Lekach). A better understanding of the easyJet business model can be found in a presentation that the company provides to its investors. You find the presentation here.  

 

  For the section "Patents of interest", we focus on patents related to computer memory: for the moment there is a general shortage and prices are experiencing hikes reaching  up to 50% month after month. It is affecting, for instance, project leaders that need to procure a cluster for scientific and industrial research, and are confronted with exorbitant prices as compared to  1 year ago. Obviously all consumers are affected, but scientists and researchers working on big data and handling very large computational domains are particularly penalized by this conjuncture.

  Already in January 2017 the price hike was alarming (see article in  pcworld) and some dire predictions were made. Things may become even worse towards the end of the year.

News from Readers

One of our readers pointed us towards an interesting and fascinating article on popular media about the Concorde and the Tupolev Tu-144, courtesy of the BBC.

It is a very interesting story about the origins, development, deplyment and retirement of the only two commercial SSTs that ever flew.

In a world where there is a return of interest on the topic (see NASA's QueSST project), and where alternative hight speed new transport methods are being developed (see the concept of Hyperloop(s) with a nice overview at theguardian), it is interesting to read about the motivations, the politcs, the successes and failures of these technological marvels for the time.

 


Patents of Interest

 

The following patents have been selected from the EPO database using the following criteria: "WORD = memory AND WORD = 'low power'  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 keywords 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.
