Attention

This launch computer requires the associated weapon to define a launched_platform_type. As documented in WSF_IMPLICIT_WEAPON, this is required even for implicit weapons that do not create new platforms. The name of the launched_platform_type must match the SystemMunition name of the fires_table as described below.

Overview

WSF_FIRES_LAUNCH_COMPUTER implements a launch computer for a short-range, indirect fire munition. This launch computer is used by the WSF_FIRES_MOVER to acquire characteristic trajectory values for max. height, and time-of-flight (given range), with which to compute a full trajectory. Discrete values for these values are stored in fires_table. If one has access to U.S. Army’s FireSim tables for desired systems and munitions, these can be used directly (see fires_table, below). Otherwise the tables can be generated from existing definitions.

Note

Multiple tables, corresponding with multiple systems for the same munition, can be used in the same launch computer definition.

Commands

fires_table SystemMunition … end_fires_table

Define a fires table with multiple entries for range, maximum ordinate, and time of flight. Ranges and maximum ordinates are measured in meters; times of flight are measured in seconds. Each entry (1, 2, … n) for range, max. ord. and time-of-flight represents a discrete possible trajectory.

SystemMunition <string-value>

Provide the System+Munition type to which this table refers. This name should be the same as the launched platform type of the launching weapon.

range_values <range-value-1> <range-value-2> … <range-value-n> end_range_values

Define a set of characteristic trajectory values for range.

maximum_ordinate_values <maximum-ordinate-1> <maximum-ordinate-2> … <maximum-ordinate-n> end_maximum_ordinate_values

Define a set of characteristic trajectory values for maximum ordinate.

Note

Either of elevation_angle_values or maximum_ordinate_values must be defined.

elevation_angle_values <elevation-angle-1> <elevation-angle-2> … <elevation-angle-n> end_elevation-angle_values

Define a set of characteristic trajectory values for initial elevation angle.

Note

Either of elevation_angle_values or maximum_ordinate_values must be defined.

time_of_flight_values <time-of-flight-value-1> <time-of-flight-value-2> … <time-of-flight-value-n> end_time_of_flight_values

Define a set of characteristic trajectory values for time of flight.
