Ultra High Efficient Wing and Moveables for Next Generation Aircraft (ULTIMATE)
The ULTIMATE (Ultra high efficient wing and moveables for next generation aircraft) joint project is investigating a "highly efficient wing" for future commercial aircraft that strives for laminarity and responds to external influences such as maneuvers and gusts with load reduction. Such a highly efficient wing is seen as a consistent next development step for future commercial aircraft and is expected to play a key role in ensuring the future competitiveness of local aircraft manufacturers. The project is based on a number of existing research results on sensor, control and actuator technology for airfoils and brings them together in a demonstrator.
Objectives
The ULTIMATE-TUB project (Load Reduction Functions for Automatic Continuously Moving Flaps and Simulation) at the Technical University of Berlin is helping to develop more environmentally friendly aircraft in the ULTIMATE network with the industrial partner Airbus and the DLR research institute. At TU Berlin, the function for an Automatic Continously Moving Slat/Flap System (ACMSFS) for a airfoil is being further developed so that, in addition to a fuel-optimal approach, the aircraft is also able to use the continuous flap system for load reduction during cruise and approach. This results in a reduction in structural mass and the ability to build more efficient elongated wings. The ACMSFS function, which has been expanded to include the "turbulence approach" and "turbulence cruise" functions, will be evaluated in flight simulator studies using criteria for flight performance, flight characteristics, economic efficiency, and eco-efficiency. The existing design and evaluation methods will be extended and refined during the studies, validated against current and future operational flight procedures, and optimized through pilot comments. This should enable rapid development and evaluation of new high-lift system variants in the future.
Project structure and tasks of the TU Berlin
The joint project is divided into four main work packages (HAP) which are coordinated by the joint project leader AIRBUS.
| HAP1000 | Design Performance Wing |
| HAP2000 | Multifunctional control surfaces |
| HAP3000 | Dynamic testing and analysis |
| HAP4000 | Design validation |
The TU Berlin is working together with Airbus and DLR on the HAP2000. The aim is to develop a load reduction and control function for adjusting the wing geometry during cruise flight to influence the pressure distribution by deflecting the continuous flap systems ("turbulence cruise"). In addition, a load reduction or control function is being developed to mitigate load peaks caused by turbulence during the landing approach ("turbulence approach"). Finally, the load reduction and control functions will be combined with the automatic continuous flap system ACMSFS from the INTELWI joint project and the overall system will be tested in the flight simulator. The new functions of the automatic continuous high-lift system will be evaluated under realistic operational conditions with airline pilots in their familiar working environment.
