“…To achieve this goal, DLR designed the AVES Software Development Kit (AVES SDK), a full set of software modules and runnable programs from the real flight simulation facility. 9 The infrastructure contains a set of rules for the user and provides space for runtime usage and different development stages. Together with a source code management system and configuration management, the AVES SDK is an evolving environment with the ability to create reproducible and standardized software versions and to support experimental software setups with the ability to connect the simulation to the development environment during runtime.…”

“…2Simulate is the underlying real-time infrastructure of the AVES Software Development Kit (AVES SDK). 9 In order to collect evidence towards the validation of the real-time capabilities of the proposed approach, the Worst Case Transfer Times (WCTT) are measured for typical scenarios with test federates in order to validate the solution against real-time constraints. Finally, a full scale implementation is carried out in AVES which includes both AVES simulators, the traffic server and the tower simulator.…”

DLR's Air Vehicle Simulator (AVES) is designed such that interchangeable cockpits of an EC135 rotorcraft and an A320 airplane can be operated either on a motion or on a fixedbase platform. While the EC135 and the A320 simulators are usually deployed standalone, there are emerging requirements to conduct simulator experiments that both simulators are involved in. Further demands include adding a traffic server for computer generated aircraft and a tower simulator to the simulation facility. To tackle the challenge of developing a complex distributed network simulation, the High Level Architecture (HLA) and AviationSimNet are selected as the underlying standards. As the AVES is a flight simulation facility with hard real-time constraints, the chosen HLA implementation, which is CERTI from ONERA, has to fulfill the deterministic processing and data exchange requirements. CERTI had to be ported to the AVES's real-time operating system QNX, and integrated into the core software infrastructure, the AVES Software Development Kit. To prove the usability of the real-time implementation, the worst case transfer times are measured for typical scenarios in order to validate the solution. Finally, a full scale implementation is carried out in AVES.

“…The simulation infrastructure designed for the FMTA-FMTA case is represented in the diagram of figure 10. The usual software architecture of the DLR AVES simulator [31][32][33] is used for the receiver aircraft and most of the software modules instantiated a second time for the tanker aircraft. The duplicated modules are identical for both aircraft, but have separated states such that both aircraft can be flown independently from each other.…”

“…As a consequence, the tremendous complexity of modern aircraft systems and the advanced functions that they include directly impact the complexity of the corresponding simulators. The AVES Software Development Kit (AVESSDK) framework 32 as well as a series of work processes that were defined in addition to the tool itself have been of great help for tackling and managing the simulation of such complex systems.…”

This paper presents the modeling and simulation activities currently conducted at DLR to support aerial refueling automation research activities. During the air-to-air refueling maneuver the tanker and receiver aircraft need to fly very close to each other, which induces a very significant aerodynamic interaction between them. Both aircraft also influence the motion of the probe-and-drogue, which needs to be modeled as well. The paper gives an overview of the developed model and simulation infrastructure, their main functionalities, and of the work needed to produce the data supporting this modeling. Unlike in many other work with similar modeling needs, RANS CFD computations were preferred to more simple techniques for the modeling of the aerodynamic interaction between tanker, receiver, hose, and drogue. The real time capable dynamic model is based on two complete aircraft dynamic model. A complete set of simulation programs (including all the complexity of modern airliner flight control systems) is used in connection with each of the aircraft. The coupled simulation programs are deployed in the DLR AVES simulator. For this, many modifications in the AVES core programs and their configurations were needed to extend it from to enable the simulation of a formation of two aircraft: some of these modifications are mentioned throughout the text from a functional point of view but without diving too much into the AVES-specific implementation details.
