The object-oriented design of the basic software allows the inclusion of a number of additional tightly integrated tools and user interfaces through dynamically loaded modules. The following discussion describes some of the key D-Six modules.
Simulation Data Import
The AeroPort tool provides D-Six users with the capability to import and manipulate a wide range of tabular data formats. The Navy’s FTP format, the International Air Transportation Association (IATA) standard data table format, the Boeing St. Louis real time and batch simulation
table format, Boeing Seattle TVP format, the Air Force/Northrop Genesis format, Lockheed ATLAS format, and many others are available for direct importation into D-Six through the AeroPort tool. Many functions designed to expedite the process of re-hosting existing datasets into D-Six
are incorporated. Transparent import and export of data through this tool not only provides the ability of D-Six to co-exist with other simulation environments, but also provides an interchange tool between external data format types.
Flight Test Analysis Tools
D-Six flight test analysis tools are tightly integrated with the D-Six simulation environment to permit efficient model validation and verification. A comprehensive flight test data editor permits the importation and manipulation of several flight test data formats, with a range of
data manipulation tools available. D-Six also provides a "Wizard" to enable users to build their own custom functions to apply to the flight test data. The flight test cross reference interface allows the graphical mapping of the flight test variable names with the associated sim
variable for driving the simulation with stick, surface, a state inputs. The overdrive feature permits the user to extract coefficient data from flight test data, drive the sim states with imported flight test or other sim signals, and compare the sim propagated coefficients with those
extracted from flight. This tool permits the user to rapidly identify sim to flight or sim to sim mismatches, and when combined with the dynamic data manipulation tools that D-Six provides, the user can quickly identify and recify model/flight mismatches.
Advanced Hardware Interface
D-Six provides an advanced input and output interface that unlike all other simulation applications, offers the user a method of interfacing their simulation with a wide range of hardware devices while allowing the simulation to remain independent of the hardware configuration, for
unprecedented transportability. The Input / Output Device (IOD) Interface enables the dynamic linking of P.C. based hardware through a standard hardware communication interface. The interface enables the introduction of hardware specific communication modules, which allows the D-Six
user to access only the hardware devices he needs, as well as providing a path for future device evolution. As a result, D-Six can currently access a number of hardware devices, such as P.C. based Ethernet, VME shared memory cards, 1553 bus interface cards, and standard D/A and A/D
cards, all of which enable the interaction with a wide range of simulation and flight hardware. Conventional game input and output devices are also supported. All of these devices are mapped through the IOD interface, which also allows dynamic reconfiguration of the simulation variables
and flags to the available input and output channels and switches. These hardware configuration files can be stored with the project or independent of it, so regardless of hardware configuration, a simulation project can be easily shared between users.
Network Interface
In order to support users that need the ability to operate multiple vehicles in a common environment, D-Six offers the D-SixNet module. This module allows the user to dynamically configure a high performance local area network using Ethernet UDP protocol for the operation of large
numbers of D-Six objects in a shared environment. A separate server application provides the network host for maximum performance and flexibility, allowing the user to graphically designate the simulation variables (beyond basic positional information) for broadcast to other simulation
objects on the network. Because of the high performance of the network, D-SixNet can support demanding network applications that require very accurate sim-to-aim positional accuracy, such air-to-air combat simulations, close formation applications for piloted and unpiloted vehicles,
re-fueling task simulation, or any simulation application that demands minimal latency between network objects.
