Newsletter #32

Some words from the Honorary President

 

Dear Colleague,

This issue of the Eucass newsletter brings to your attention, in addition to the usual survey of scientific publications from European journals and Institutes and patents recently granted by the EPO, several important announcements.

 

I - Obituary

 

First we would like to report the sad loss of our dear friend and Eucass co-founder Max Calabro.

Max was a cheerful and enlightened man. He believed in the European dream, a dream where all countries of the continent would buttress the values of democracy and progress hand in hand for the advancement of aerospace sciences, his dear field.

From the very beginning in January 2004 until just a few months ago, he supported the Eucass project with absolute dedication. He was remarkably apt at visiting and assessing the value and attractiveness of conference sites. Until very recently and since the very beginning, he managed the conference programmes and contributed to the elaboration of the opening ceremonies and plenary sessions of invited presentations.

His field of expertise was rocket propulsion. A graduate of the Lyon (France) INSA engineering school, he served SEREB, then Aérospatiale, which was to become EADS. He took part in the UNMOVIC UNO mission to Iraq in his capacity of ballistics expert. He was distinguished as AIAA Fellow, SRTC Emeritus member, IAF IPC member and 3AF Emeritus member. He also was a member of the IAA.

On Feb. 28, 2004, a momentous meeting with some prominent Russian colleagues from RAS takes place in Paris. There we took the decision to hold the very first European aerospace conference the next year in Moscow.

Max and the late Russian Academician Mikhail Ivanov from ITAM in Akademgorodok, Russia, also a Eucass founder, ready for a dinner in a fine restaurant.

Max, one of the prominent fathers of Eucass, signs the charter he helped to draft, 19 April 2006, Rhode St Genèse, Belgium

 

 

II – Important conference announcements from Eucass and partners:

 

 

We are pleased to announce two Eucass workshops due next year and one from a partner group:

 

The 2nd Aerospace Thematic Workshop (ATW) on “Fundamentals of Collisions of Fast Particles with Surfaces”  is a must for several fields of importance to aerospace research, namely electrode erosion in plasma thrusters, PECVD, space environment damage, energetic material decomposition, etc. We are at the cutting edge concerning quantum treatment of particle interactions, advanced non-intrusive diagnostics, simulation and modelling. The 20 invited lectures are presented in a seminar mode, conducing to lively discussions between communities that never interact with one another. The meeting takes place at the prestigious Les Houches School of Physics in the French Alps April 5-10, 2020. For more, see the workshop webpage.

 

The 1st Eucass Workshop on “Advanced Aerospace Designs by Innovative Flow Control Technology”  due in Lille, 18-20 May 2020, a joint venture between CNRS & Onera involving IMFL and the participation of Euroturbo. The objective is to place the various scientific communities involved in front of the operational and technical realities. The invited speakers are among the most eminent specialists in both aerospace industry and research institutions and academia. The event will be a unique opportunity for European and worldwide researchers to showcase their work and to exchange with the most prominent academic and industrial specialists. See details on the local organiser webpage.

 

Conference on Active Flow Control and Applications: From Model-Based to Machine Learning Strategies: This is the very last minute request for submitting your paper to the conference (deadline is 11 November). It focuses on wake-flow control and gathering two scientific communities spanning fluid mechanics (physics and applied mathematics) and control theory (nonlinear control, observers, and machine learning). Wake-flow control aims at reducing drag in the transportation industry. Active flow control is an appealing approach but it faces scientific challenges like the design of reliable and real-time tractable models. The track will therefore cover all topics related to the modeling, identification, feedback control, state observation and optimization for flow control applications.  More details available here.

 

...and very important info concerning the recent Eucass conference in Madrid:


all 578 relevant papers have received a DOI and are now downloadable free of charge from our website

Patents of Interest

In this issue of patents of interests, we will like review recent filings relative to augmented supported systems for aviation. 

Therefore, the following patents have been selected from the EPO database using the following criteria: "PUA12 >= 20190101 and  WORD=Augmentation AND  WORD=System and WORD=aircraft"  and selecting a few interesting patents that could have repercussions on our field. In this case, this means all patents whose A1/A2 documents both have been published after January 1, 2019. 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.
