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.

Ercoftac Logo

Ercoftac's  BPG for CFD of turbulent combustion including emission prediction and virtual prototyping (Gas turbine engines, IC engines, & Process furnaces) will be held the 11-12 December at TU Delft

Please note each delegate will receive a free copy
of the BPG Combustion CFD book (normal price €230).

In this course, the objective is for participants to  learn the best practices in CFD of combustion systems:

- How to select models
- How to validate numerical simulations
- Which accuracy to expect

Interactions between fuel injection, turbulence,heat release and thermal radiation (critical in determining flame structure and pollutant emissions) are studied in depth.

ECCOMAS Logo

ECCOMAS is organizing its advanced workshop on Platform for Aircraft Drag Reduction Innovation (PADRI 2017) shortly.

The open workshop focuses on a test case proposed for computation reproducing, even at low velocity, a typical shock wave pattern in the region of the junction strut-wing of an aircraft.

The workshop intends to contribute to fill the gap between the different technology models and their application.

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.

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.

News from Readers

One of our readers sent us an interesting article of Nature about perovskite. Perovskite Solar Cells are extremely interesting and generally regarded as the next generation solar cells, after the mature and currently available crystalline silicon based ones. The European commission is for example sponsoring (or has funded research) for many projects about perovskite in the H2020 framework (see for example this, this and this). 

Perovskite cells have the advantage of a definitely smaller carbon footprint (i.e. require much less energy for production since no high temperatures are necessary for their manufacturing), have significantly smaller costs, can be used as windows, but have a big stability problem. 

Some claim that commercial perovskite could arrive on the markets as soon as this year, but the 2018-2020 target is more realistic, and the advances illustrated by the Nature article raise hopes of a rapid commercialization.

Solar Cells do not usually play a big role in our readers' research fields (except of course for satellites and alike), but the new characteristics of the Perovskite Solar Cells (PSCs) could allow this role to expand. 

 


Patents of Interest

 

The following patents have been selected from the EPO database using the following criteria: "WORD = perovskite AND WORD = tandem AND WORD = 'solar panel' 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.

The keywords tandem is related to solar cells that adsorb from different portions of the light spectrum thanks to their particular manufacturing process to increase efficiency.

Patents of Interest

 

The following patents have been selected from the EPO database using the following criteria: "WORD = noise AND WORD = reduction AND WORD = aircraft 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.
