New Track integrated Electrical Single Flap Drive System

Objective

The NEFS consortium is proposing a track integrated single flap drive system for the deployment of wing high lift surfaces. The new system is a fundamental change compared to state-of-the-art high lift systems and will significantly improve the availability, maintainability and flexibility of the system and hence the performance of high lift systems when compared with state of the art systems flown today in commercial transport aircraft. This new technology is an enabler for new functionalities, which are developed in RTD projects like AWIATOR, NACRE or ATEFA.

This proposal describes an RTD approach to develop a distributed flap drive system. Major objectives are to increase the availability and reliability, add additional functionalities, simplify installation and advance passengers' safety through higher surface redundancy by use of the high lift systems.

The major targets of NEFS are:
- Enable new functionalities of the high lift system via differential flap setting (DFS), like accelerated vortex decay, roll trim and roll control support
- Reduce the operational interruption caused by high lift systems by at least 15%
- Improve the drive system efficiency by at least 25%
- 2%
- 3% in L/D improvement in cruise via differential flap setting (DFS)
- 20% weight reduction of the flap track beam due to highly integrated composite design
- 5% cost reduction in the manufacturing and assembly of the flap track beam due to minimized part number
- Improved Maintainability
- Reduced installation effort (for design and manufacturing)

With the above- mentioned benefits NEFS is directly related to the present EU work programme, chapter "Strengthening Competitiveness".
