Brazier loads and detailed Rib 4), has

been performed the preliminary analysis.

The following picture shows the Tsai-Wu

Margin of Safety and Failure Indices,

recovered at Rib 4, under the Load Case

NZPOS_G002.

PRO Solicitations from ITD Leader about Research Challenges of

Relevant Importance and Possible Real Future Applications

Long and Intense Interactions with PMI within the Cluster that Give Some Significant Results:

The Universities can Understand Better the Problems of PMI to Innovate Process and Product;

The Universities Have the Possibilities to Convince and Accompany PMI in the Innovation Process.

Possibility to Follow the Development of New Technologies from Low TRL to Higher TRL and see their Application to Large Ground or Flying Demonstrators

Last but Not Least, possibility for Young Researchers (and Students) to be Trained ( and making Publications !!) on Research Themes of Relevant Importance and Very Actual.

Consideration about AIRGREEN Cluster Participation

to JTI “Clean Sky –GRA ITD

21

Consideration about Universities

Participation to JTI “Clean Sky –GRA within

AIRGREEN Cluster

CONTRO

• Need to Co-finance the Research Activities at a Rate of

50% that is Not Easy to Sustain;

• Not so much Interactions with Universities outside those

involved in the Cluster (in Airgreen are All Italian and in

GRA no others Cluster with Universities !!)

• Problems for other Research Teams of the same University,

involved in GRA, that want to Participate to CfP of GRA ITD

• Interactions with others ITDs Research Activities is NULL !!!

22

STARTING POINT

The balance from PRO e CON is in the Green (+) region !!

PROPOSITIONS

All Universities belong to AIRGREEN Cluster, have expressed the intention to be involved in the Clean Sky 2 in the form of Cluster with PMI and Research Centers, but with a more specific technological focus;

In order to overcome the problem of participation of a larger number of research teams , belong to same University, some large Universities think that will be better to participate as “alone” Core Partner to a specific ITD or IADT ;

The alternative approach at the previous point , will be to give the possibility to Universities to be involved in different Clusters of the same ITD o in different ITDs;

Less co-financing and more founds (like that reserved to CfP !!)

More Universities in different Core Partners Cluster;

A little more interaction with other ITDs and IADTs .
