Missiles are simulated as platform-level entities in VR-Forces.

The missile model is used to represent various categories of missiles, such as:

• TOW Anti-tank
• AIM-9 Sidewinder Air-to-air
• MK-48 Torpedo

Missiles are typically fired from a launcher, a behavior model subsystem configured as part of the firing entity.

Core Elements of Missiles

Missiles in VR-Forces share certain common elements. A typical missile in VR-Forces is always configured with the following:

• DtMissileStateRepository -- Holds state information specific to missiles
• DtSimIndividualLocalEntityNetInterface -- Handles network publishing (platform-level entities)

Component Systems that make up a Missile

Missiles also share many of the same systems and simulation components (controllers and actuators). To examine the systems typically configured on a missile, we'll look at a specific instance of a missile, the TOW2 missile. Differences arise between the various types of entities as a function of which particular sub-systems are configured on them, and the parameter values it is configured with.

A Specific Example: TOW2 Missile

Defined in parameter file tow-missile-platform_1_2_2_225_1_1_3_-1.ope

The figure below shows which systems and simulation components are configured as part of a TOW2 missile. The boxes (nodes) represent either a system of components (DtComponentSystem) or indivdiual DtSimComponent classes. The edges connecting the boxes indicate port or port group connections between components.

TOW Missile

Systems

• Missile Damage -- Models the damage characteristics of the missile.
• Missile Dynamics -- Models the movement behavior of the missile.

Other Simulation Components

Individual DtSimComponents (not organized as part of a system) that make up the rest of entity:

Sensors:

There are no sensors configured as part of a missile entity.

Controllers

• Set-data -- Respond to DtSetDataRequests, such as set location, set heading

Actuators

There are no actuators configured as part of a missile entity.
