BALANCE Report Summary

Funded under: H2020-EU.3.4.5.4.

Periodic Reporting for period 1 - BALANCE (Business Aviation Laminar Nacelle)

Reporting period: 2016-01-01 to 2016-12-31

Summary of the context and overall objectives of the project

BALANCE (Business Aircraft LAminar NaCellE) is a 20 month research and innovation project in the field of aeronautical engineering, launched in January 2016. The global strategic objective behind the BALANCE project is to provide technologies that enable reduction of the drag of the nacelle through increasing the portion of laminar airflow.
The target is to reduce drag by up to 1 % at aircraft level through achieving a laminar flow over 30-40% of the nacelle length. These objectives will assist the development of European capability within the nacelle domain such that Europe is well positioned to provide equipment through the forthcoming business aircraft.
To achieve this, the project will develop key technologies, in particular nacelle architectural options, improved design approaches for reduced steps and gaps, and revised engine access points to enable means of developing better, competitive solutions for future business aircraft nacelles, and to develop key objectives detailed below so as to be best placed in that regard.
The BALANCE project aims at developing new nacelle approaches, and optimising and integrating this equipment within the engine-nacelle zones in a more effective way, so as to deliver new technologies up to TRL5 that match the requirements of lower drag business jet nacelles. BALANCE will enable reduced fuel burn for business jet aircraft by achieving the following main objectives:
o Reduce the drag produced by the nacelle using laminar flow by 1% at aircraft level.
o Ensuring the solution does not impact the nacelle weight adversely
o Ensuring the laminar flow solution does not imply more effort in the production and operation aspects of the product lifecycle.
These technologies will target integration into the future propulsion systems and aircraft applications with expected entry into service (EIS) date between 2020 and 2030

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

BALANCE is organised in a total of 6 Work Packages (WP), of which three have been worked during this period, due to their sequential nature of planning.
WP1 – Study several new concepts – This work package consists in establishing the list of the technical solutions allowing to reach the criteria of laminarity from 30 to 40 % of the length of the nacelle installed at the rear fuselage. With the aim of classifying the various solutions, it will be necessary to list the various major contributors of no-laminarity for traditional architecture.
Within this Work Package 2 major, and 2 derivatives concepts of nacelles have been developed, each exhibiting laminar traits focussing around means of achieving lower drag around the forward section of the nacelle whilst maintaining functionality and maintenance aspects. The advantages and constraints for each concept have been defined.
WP2 – Analysis of two concepts and selection of the best – This work consists in establishing a short list of two better technico-economic solutions performing at best selection criteria established during the previous work package and to lead a Preliminary Design Review.
Within this Work Package, a preliminary scorecard has been developed. This is awaiting approval from the various expert teams such that it can be used to downselect two concepts from Work Package 1 for continuation in the subsequent work packages.
WP7 – Project Management – is to ensure the Programme management of the project, including Dissemination Plan and material, IPR management, project management and decision making committees, management procedures, quality plan, project management tools, etc.
Within this work package, the Consortium Agreement was completed and signed, and liaison has been made, including Non-Disclosure coverage, with another project called NACOR which is being run in parallel by ITD-Airframe.

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

BALANCE will provide to TRL5 new concepts and approaches aimed at reducing the drag present on a business jet nacelle over the frontal nacelle length. Concepts will be examined to achieve the 30-40% length coverage, whilst assessing the impact in IPPS functions and performance in order to develop the best concept capable of achieving the targeted 1 % drag reduction at aircraft level. Building upon nacelle research undertaken in National programmes, BALANCE will lead to a nacelle improvement which supports the ACARE Strategic Research and Innovation Agenda roadmap of a propulsion system design in the short and medium-term that exploits the residual potential of current and emerging designs through their evolution and optimisation. The expected global improvements of these efforts are addressing mainly the environmental aspect, but will also have a positive impact on developing and maintaining industrial leadership and societal needs by providing the technology needed to keep the European aero-engine and equipment industries ahead of the competition.
BALANCE will, for the business jet nacelle sector, contribute to the huge effort required to maintain global leadership for aviation in Europe and meeting the needs of its citizens, the sector being a key component of the existing European Gross Domestic Product (GDP) and employment. The forthcoming challenges expressed by the Business Jet community of over 9,450 new business jets required over the next 10 years sets a large market opportunity for enhancing the European footprint. Current propulsion system nacelles are able to be sourced from companies based outside of Europe meaning that the achievement of business jet improvements can be reliant on the achievements of non-European companies. BALANCE aims to support further development within Europe of indigenous solutions in order to support increased revenue, and hence jobs within the EU.

However, with the BALANCE technologies being still under development, no measurable socio-economic impact or wider societal implications could be identified so far.
