Modeling and Simulation in Aviation




Aligned with the plenary talk that I mentioned in my previous post, we are organizing a special interest track in ASIM 2016 that will be conducted in September in Dresden. Since decades, the philosophy of modelling and simulation is widely employed in the aviation community. The applications cover a wide range from modelling small sub systems up to developing large flight simulators. New standards, techniques and methodologies have been developed to tackle the complexity of problems and solve the challenges of tomorrow. Now, this Special Interest Track endeavours to establish a platform under the umbrella of ASIM to share modelling and simulation efforts from the aviation community. I would like to encouraged authors to submit papers as applied to the fields of aviation and aerospace systems. The following is a recommended but not exclusive list of topics:

  • Modelling and simulation air vehicles
  • Flight simulators
  • Air traffic simulation
  • Simulation tools 
  • Validation and verification 
  • Model integration
  • Distributed simulation 
  • Hardware-in-the-loop simulation

Model-based engineering of aviation and aerospace systems
Contributed papers can be short papers with 2-4 pages or full papers with 6-8 pages. They will be peer reviewed and – if accepted and presented at the conference – appear in symposium proceedings. The important dates are as follows:
  • Abstract (1-2 pages) submission: 08. May 2016 
  • Notification of Acceptance: 06. June 2016 
  • Camera-ready Paper: 24. July 2016
  • Symposium Date: 7. – 9. September 2016
Please do not hasitate to contact me for further details.

Flight Simulation for Tomorrow's Aviation

ASIM(Arbeitsgemeinschaft Simulation) is association for simulation community in German speaking nations. It has various sub-groups two of which are GMMS (Grundlagen und Methoden in Modellbildung und Simulation), dealing with the fundementals and methodologies of modeling and simulation, and STS (Simulation Technischer Systeme) which is working on simulation of technical systems. These two groups are historically share (almost) the same community. I am also trying my best to contribute them. Each year we make a two-days workshop in which we meet around 100 people and present each other what we are doing. This year, we are meeting in Lippstadt. Therefore I am here in this beautiful small German town. 
This year, apart from two papers that I contributed, I will be supporting the workshop with a plenary talk. The title of my talk will be "Flight Simulation for Tomorrow's Aviation".  Flight simulators have been operated within the aeronautics community for human factor studies and flight systems development for the last half century. They are virtual test beds, to evaluate concepts, conduct pilot-in-the-loop experiments and collect valuable user experience data. The German Aerospace Center (DLR) Institute of Flight Systems is involved in developing and employing research flight simulators for more than 40 years. The first generation ground based simulator of DLR was built for the HFB 320 FLISI in 1970s. The ground based simulators for ATTAS and ACT/FHS EC135 were later introduced as the second generation. The development of these simulators started at 1980s and they have been used until 2010s. In 2009, DLR Institute of Flight Systems commissioned a next generation reconfigurable research flight simulator, called the Air Vehicle Simulator (AVES) in order to address the research requirements for tomorrow’s aviation. AVES has been operational since 2013 with its two cockpit infrastructures: an Airbus A320 and an Airbus Helicopters EC135. To date, various research projects have been carried out in AVES. Two of them that will be introduced in this talk as examples are Manual Operation of 4th Generation Airliners (MAN4GEN) and Enabling Technologies for Personal Air Transportation System (myCopter)
As an important difference from commercial flight simulators, research flight simulators require high flexibility and adaptability in almost all aspects from flight systems and flight dynamics models to cockpit displays or control loading systems. Therefore, flexibility and adaptability inspired the overall simulator software design. Accordingly, 2Simulate, the real-time distributed simulation infrastructure of AVES, is being empowered by recent simulation engineering research activities that target at enhanced composability and interoperability. After a gentle introduction of 2Simulate, this talk will present a collection of these recent efforts that enable model integration at various levels. The 2Simulate Modeling Language effort proposes an Application Programming Interface for C++ model development. With Simulink Coder™ 2Simulate Generic Real-time Target; code generation for MATLAB/Simulink models is tailored for AVES. Moreover, the MATLAB/Simulink 2Simulate Toolbox that is currently being developed intends to accommodate AVES users with model-in-the-loop testing capabilities. Through 2Simulate Functional Mock-up Interface (FMI) Support, we are aiming at a FMI integration pipeline in AVES. Finally, 2Simulate High Level Architecture (HLA) Support endeavors providing capabilities for creating and joining HLA federations based on AviationSimNet Federation Object Model (FOM) in AVES.
