FlightSim is a research project in the joint MOVE.ON project led by Airbus and funded by the German Federal Ministry of Economics and Technology as part of the National Aeronautics Research Program (LuFo IV). The aim is to build and develop a computer-aided tool for evaluating the flight performance and flight characteristics of commercial aircraft with novel high-lift systems.
High-lift aids are used on commercial aircraft for takeoff and landing. These are extended during takeoff to increase the lift coefficient and thus shorten the takeoff distance. During landing, high lift coefficients lead to a reduction in approach and touchdown speeds and can also affect the flyable descent rates and runway angles.
The major cause limiting high lift coefficients is flow separation. Therefore, new high-lift concepts with passive or even active flow control are being investigated for future commercial aircraft, which should ensure that flow separation only occurs at higher angles of attack and higher lift coefficients compared to conventional concepts.
In order to be able to investigate the influences of such new concepts on flight dynamics at an early stage, a computer-aided tool (tool) is being developed as part of this research project. This will be used to compare and evaluate different designs in terms of flight characteristics and flight performance. The results will be used in the design of the high-lift configuration.
The aim of the project is the flight-mechanical evaluation of aircraft with novel and innovative high-lift concepts by means of a computer-aided tool.
In the first phase of the project, criteria will be identified and compiled that will make it possible to examine and evaluate an aircraft in terms of its flight performance and flight characteristics as early as the preliminary design stage. These criteria will be integrated into a software tool that uses, among other things, a flight simulation as the basis for calculating the flight dynamics. The same flight simulation will be implemented in a research flight simulator so that flight simulations with pilots are also possible.
In the second phase of the project, pilot tests will be conducted from which criteria for the design process will be derived. Approaches and departures will be simulated so that the interaction between the modified high-lift system and common, but also novel, approach and departure procedures can be investigated and evaluated.
Tasks of the TU Berlin include the following:
|Definition of the evaluation criteria for flight characteristics
|Creation of the simulation environment/tool chain and validation tests
|Pilot tests and evaluation of control surfaces
