COBRA
COBRA (Innovative Counter rOtating fan system for high Bypass Ratio Aircraft engine):
COBRA is a 3.5-year FP7 collaborative research project between Europe and Russia (under grant
agreement № 605379), commenced 1st October 2013. Coordinated by Onera (N. Ben Nasr), it
associates 9 European partners with an overall budget of 3.5 M€.
The philosophy of the COBRA proposal is to use the complementarity of EU-Russian expertise in
“ducted architectures”; it is expected that this will provide advantages in dealing with the noise and
installation challenges required to overcome the insufficient noise performance of the counterrotating fan tested in the VITAL project. Higher bypass ratio designs (use of gearbox becomes
mandatory) with much lower blade tip speeds and blade counts will be explored, whilst at least
maintaining and maybe increasing the very good aerodynamic efficiency already achieved.
The goal of COBRA is to promote an effective cooperation between EU and Russian scientists. The
project is structured to benefit from the existing skills of EU and Russia in the design and the multidisciplinary optimisation of UHBR1 CRTF2 architecture to assess at the whole engine level the
capabilities of the UHBR CRTF in terms of performance and acoustic levels. Comparisons will be made
with the VITAL CRTF results and with the strategy for the CROR3. These activities will include
extensive CFD-CAA4 and structural/mechanical computations and experimental studies.
COBRA will integrate the benefits and the results of:
Previous EC-funded research projects such as:o the VITAL project WP2.4 in respect of CRTF specifications, new fan architecture, test
campaign expertise and validation of tools,
o the DREAM project in respect of noise reduction within the design process of CROR
architecture and validation of design tools, and,
Russian knowhow in respect of UHBR CRTF architecture as in the NK-93 engine designed by
JSC KUZNETSOV (partner in the COBRA project).

NINHA-final-workshop
NINHA (Noise Impact of aircraft with Novel engine configurations in mid- to High Altitude
operations) was successfully completed on 30 September 2013.
The final workshop to review project results and obtain feedback from relevant stakeholders from
outside the consortium took place in Sevilla, Spain, on 23 September. A total of 21 participants
discussed the main achievements and identified remaining gaps and potential future work related to
en-route noise, in particular, of open-rotors.
The workshop agenda was as follows:
1. NINHA Project Overview
2. Overview of US activities
3. En-route Noise Research for Novel Engine Configurations - Industry vision
4. Exploitation Session
- View from the NINHA consortium; conclusions and potential future work
- International Collaboration
- Roundtable and Feedback from participants.
It was concluded that NINHA has brought the knowledge of open rotor en-route noise a significant
step further, providing a toolkit capable of predicting en-route noise levels and assisting in assessing
impact in comparison with current generation aircraft.
It was recognised that gaps still exist, especially in relation to the subjective response to the specific
noise signature typical of open rotors, and, to improved prediction tools and a better understanding
of atmospheric propagation effects. It has been shown that the latter may cause the noise levels
received on the ground to vary very considerably.
Most of the identified topics are considered suitable for a collaborative research exercise, combining
EU and US efforts and resources in these non-competitive fields. First steps in this direction have
been defined.

AFloNext
The AFLoNext project aims to enrich further the available portfolio of flow-, load- and noise-control
technologies realising mature solutions by raising significantly their Technology Readiness Level (TRL)
over the next few years, therefore widening opportunities for selection of yet other further advanced
technologies for future aircraft product integration (2025+).
Such technologies considered in AFloNext are ones either not addressed or only conveyed up to TRL
2-3 in the Smart Fixed Wing Aircraft (SFWA) Studies in Clean Sky. It is planned in AFloNext to qualify
the most favourable of these technologies up to TRL 4-5 to make them ready for potential selection
for a large scale integrated demonstrator project in the timeframe of 2015-2018 (i.e., potentially part
of a SFWA within JTI Clean Sky2 as “the integrator project” in the EC framework).
In respect of noise control, AFloNext will focus on airframe noise sources such as flap side edge noise
and installed landing gear noise by developing aero-acoustic design concepts of components, for
which turbulent flows have previously been identified as significant sources

Dr Gareth Bennett reports on:
Trinity College Dublin Coordinating two Clean Sky Projects,
and,
Competitive Feasibility Fund launched by Irish Government to stimulate business activity in
the aviation sector
1. Trinity College Dublin Coordinating two Clean Sky Projects
The Clean Sky Joint Technology Initiative is a Public-Private Partnership between the European
Commission and Industry implementing the Level 3 project approach of FP7.
TCD is currently coordinating two ambitious collaborative projects, WENEMOR and ALLEGRA, within
the Green Regional Aircraft (GRA) Integrated Technology Demonstrator ( ITD) of Clean Sky with Alenia
Aermacchi as the ITD Leader.
1.1 Wind Tunnel Tests for the Evaluation of the Installation Effects of Noise Emissions of an Open
Rotor Advanced Regional Aircraft, WENEMOR1, 2011-2013, total budget €2,000,000
WENEMOR has been developed in response to the requirements described in the Clean Sky-ITDGRA call for proposals referenced under SP1-JTI-CLEAN SKY-2010-4 and named “Aero-acoustic
noise emissions measure for advanced Regional Open Rotor A/C configuration”.
WENEMOR addresses the topic by conducting aeroacoustic measurements in an open test
section of a large low speed wind tunnel, on a complete reduced scale modular model of
different configurations of an aircraft with installed open rotor systems, operating in both
“pusher” and “tractor” modes.
The aim of these tests is the creation of an aeroacoustic database with two main applications:to characterise the emitted noise and evaluate the installation effects of these different
configurations, and,
to allow the validation of GRA ITD aeroacoustic simulation codes.

1.2 Advanced Low Noise Landing (Main and Nose) Gear for Regional Aircraft, ALLEGRA, 2012-2014,
total budget €2,000,000
During landing approach, when engines are operating at low thrust, the noise of the airframe
contributes strongly to the overall noise signature of modern aircraft. Airframe noise is generated
by airflow around components of the aircraft. The main sources of airframe noise are the high
drag elements such as landing gears and also the high lift devices on the wings. For larger
aircraft, it is the landing gear noise that dominates.
This project, ALLEGRA, therefore, focusses on the design and test of Main and Nose Landing Gear
noise reduction concepts. The consortium is comprised of a wellknown aeroacoustic wind tunnel
company and SMEs from around Europe with specific competence in landing gear design,

manufacturing and structural analysis. In addition, two of the EU’s most distinguished
universities are taking the lead in computational aeroacoustics, noise measurements and data
analysis. All partners have participated and delivered in earlier EU projects, in some cases
including extensive coordination.
The outputs of ALLEGRA will result in pragmatic validated solutions to reduce noise and
emissions and improve fuel consumption. These solutions are being developed in conjunction
with an EU aircraft manufacturer to ensure feasibility and to reduce time to implementation.

2. Competitive Feasibility Fund launched by Irish Government to stimulate business activity in the
aviation sector
The new Enterprise Ireland Competitive Feasibility Fund for the Aviation Sector was launched on 1st
July 2013 by the Irish Minister for Jobs, Enterprise and Innovation, Richard Bruton TD. The fund,
which can provide up to €25,000 per project, is part of the Government's Action Plan for Jobs and
follows on from the Government’s publication of the ‘Shannon Aviation Business Development Task
Force Final Report’, which is focussed on building an environment which will encourage and support
entrepreneurship and business expansion in the aviation sector.
The fund of €375,000 is open to new startup companies or individual entrepreneurs to investigate
the viability of a new significant growth oriented business or proposition in the aviation sector. It is
also open to established companies or groups of businesses who wish to examine the potential for
expansion, diversification or spinning out of a new enterprise in the industry.

X-Noise input in ECATS activities
The main topic linking aircraft noise research (and so, X-Noise EV) to ECATS is interdependencies.
As a consequence, it is important to review existing major operational practices at airports that are
or might be relevant in respect of noise and emissions trade-offs; collecting data and undertaking gap
analyses.
Examples of such are assessing the impact of various types of proposed new (or newly introduced to
specific airport/type of airport) operational procedures such as:Continuous Descent Operation/ Approach;
Controlled engine taxi-in/out;
http://xnoise.eu
Climbout .
Assessing consequences for airport operational capacity as a result of using different operational
procedures is also of great interest within ECATS.
Trade-offs
Trade-offs have to be assessed not only between noise, fuel and emissions, but also between the
most important individual emissions themselves and between local and global environmental
impacts.
Europe is well blessed with aviation-related environmental models. However, these were generally
developed in isolation in different member States for different purposes. For effective policy
assessment, it is important to realise this previous modelling investment by creating a technical and
managerial system to allow these various models to work together, from common input data, to
provide interdependency-relevant policy analyses and forecasts.
This topic may be a new research area for joint effort for the teams of X-Noise and ECATS.

GATG
General Aviation Task Group
From Denis Gély, Onera
Created in 2010, the General Aviation Task Group (GATG) now brings together more than 100 pointsof-contact in 16 European and other X-Noise collaborating countries.
The scope is focussed on noise generated by small propeller airplanes with a mass of less than 8.6
tonnes, certificated to the standards of the ICAO/CAEP (International Civil Aviation Organization /
Committee on Aviation Environmental Protection Chapters 6 and 10).
First GA workshop
Noise at source and impact, the first GA workshop, was held in Marseille, France, October 2011. All
aspects were covered from the noise at source (propeller and engine) to airfield and certification
issues. The agenda, the attendee list and the presentations can be downloaded from secure
website1:
https://www.envisageportal.eu/knowledgeTree/browse.php?fFolderId=923
Contribution to Flightpath2050 assessment
In 2012, the GATG provided contributions to the Flightpath2050 assessment of ACARE2 SRIA3. The
relevant issues and noise reduction solutions for light aircraft were investigated under 7 main topic
headings. The text of the contribution can be downloaded from:https://www.envisageportal.eu/knowledgeTree/browse.php?fFolderId=1083
Second GA workshop
This September 2013, the GATG organised a secondr workshop dedicated to Exhaust/Intake Systems
Application – Mufflers.
This workshop was coupled with an international general acoustics congress, Internoise2013,
Innsbruck, Austria, in order to bring together many of the specialist community from other industries
(automotive, energy, etc).
The workshop was attended by 16 people representing 9 countries (UK, Sweden, USA, Germany,
Egypt, France, Brazil, Malaysia, Senegal). The presentations dealt with experimental techniques for
http://xnoise.eu
acoustic characterisation of exhaust system components, numerical simulation in muffler design,
modelling and optimisation processes, the performance of micro-perforated panel absorbers and
engine gas exchange aspects.
At the end of the workshop a roundtable discussion addressed the following open questions:•
•
•
•
•
•
•
•
•
What is the most important technological development (in terms of either hardware or
theoretical modelling) required for the improvement of mufflers?
What are the needs in terms of computational tools?
Which new materials might be available now?
Are the Active Noise Control technologies mature enough?
Does the cost of Advanced Technology Mufflers development bring a (practical) difficulty for
implementation on small aircraft?
What is the maximum possible contribution of mufflers to the reduction of the total noise
level of a typical General Aviation aircraft?
Is the installation effect an important issue for General Aviation?
How can external factors (e.g., politics, certification authorities) be influenced to stimulate
the development of quieter General Aviation?
What about Performance/Acoustic reduction optimisation?
