European Workshop on New Aero Engine Concepts

Towards a sustainable and environment friendly future for air-traffic

The NEWAC (New Aero Engine Core Concepts) conference, which took place in Munich on 30 June – 1 July 2010 under the coordination of MTU Aero Engines, offered insight to 109 experts into innovative core engine technologies, and presented solutions developed by NEWAC programme.

The workshop summarized the 4 years of international collaborative research between 40 partners composed of a large number of stakeholders in the European industry including all major aero-engine manufacturers, innovative small businesses, universities and research centres. The workshop included an exhibition and over 40 technical presentations covering research into innovative aero engine technologies and design solutions for:

         Four new aero engine core configurations 

         Intercooler and recuperator integration 

         Novel lean combustion concepts for very low NOx emissions 

         Further innovative core concepts 

         Design and manufacture of efficient and lightweight compressors 

         Compressor stability enhancement.

Within four years of extensive research, four new, highly innovative core engine configurations for game-changing propulsion systems were explored, which also included the integration of intercoolers and heat exchangers; some of the technologies are already being validated. New, lean combustion concepts for very low oxides of nitrogen (NOx) emissions were developed and tested. The partners in the program conducted intensive test runs with compressors and novel, active control systems to improve stability and efficiency. These tests, too, yielded very promising results. The focus of another study conducted as part of the program was on the design of efficient and lightweight compressors.

The importance of European Research projects was highlighted in the presentation of European Commission by Daniel Chiron, Deputy Head of Unit Aeronautics and Scientific Officer.

Besides NEWAC a comprehensive overview of current major European aero engine research projects and future research opportunities has been presented:

         VITAL (EnVIronmenTALly Friendly Aero Engines), a European funded research programme in the Sixth Framework Programme, launched in January 2005 running for 63 months. Coordinated by Snecma, this project unites 53 partners from 15 countries and aims to develop engine technologies to reduce noise by 6 decibels and CO2 emissions by 7%.

         dream (Validation of radical engine architecture systems) is a European funded research programme in the Seventh Framework Programme led by Rolls-Royce. 44 partners bundle their expertise to investigate new engine concepts for future air transport. The project technology themes include advanced technologies mainly devoted to fuel consumption / CO2 reduction, whilst retaining acceptable noise levels.

         The Clean Sky Joint Technology Initiative is a public-private partnership intended to accelerate the introduction of technologies to reduce the environmental impact of the air transport industry. Over a seven year period, the gross programme of €1.6bn will develop technologies to reduce CO2, NOX and noise emissions from aircraft through novel airframes, powerplant developments, alternative operating patterns, more efficient airframe and powerplant supporting systems and design for reduced manufacturing and end-of-life impact.

The workshop provided also an outlook on further research efforts needed to fully realize or surpass ACARE 2020 objectives. In the concluding high-level panel discussion the benefits gained were summarized and an outlook for the exploitation of the technologies in future applications was provided.
