AWIATOR - Aircraft wing with advanced technology operation
Overview
Background & policy context:
We are currently experiencing an tremendous increase of some 5% per year in world wide air traffic. To cope with this, the future environment of transport aircraft will be defined by new requirements: more stringent noise regulations, fees or limitations on gaseous emissions, new air traffic management, strong increase of aircraft frequency, and increased demand for passenger comfort. The design of a new aircraft has to take these requirements into account by applying new technologies, existing aircraft may be retrofitted with such technologies. Within this project, the application and especially the integration of these technologies on aircraft level will be demonstrated by flight tests on a large flying test bed. To do so, basic work on ground is needed, by wind tunnel tests, rig tests and aircraft ground tests.
Objectives:
The overall target of this Technology Platform project is the integration of advanced technologies into novel fixed wing configurations, aiming at a further significant step in improving aircraft efficiency and reducing farfield impact.
To achieve this target, the following specific industrial objectives have been identified:
- reduce the vortex hazard, by this decrease the separation distance behind a large aircraft by 1 nm;
- apply specific flight procedures using new devices validated in this project, by this reduce noise by 2 EPNdB;
- increase cruise performance (L/D + 2%, Fuel Burn -2%) by new devices and load control strategies;
- increase low speed performance by using new devices and load control strategies, in detail increase L/D by 2.5;
- decrease new aircraft structural weight by applying new load control strategies, in detail reduce weight by 5% using existing devices and by 10% using new devices;
- aerodynamic characteristics, systems and structures will be optimized in a multi-disciplinary approach by controlling lift distribution, wake vortex, and wing loads.
Methodology:
Within three technical work packages of this project, the far field around an aircraft (e.g. vortex hazard reducing services), the near field impact (e.g. large winglets), and flow & load control (e.g. adaptive elements ) will be addressed. In an integrative work package, flight clearance, harmonized ground test and flight test programmes. and the effect of single technologies and their combination on aircraft level will be investigated.
