Reuse of a J-MASS compliant missile model as a SAM model

Abstract

The Joint Modeling and Simulation System (J-MASS) provides an object oriented software development environment that supports the development and reuse of models, configuring the models and the scenario using graphical tools, executing the simulation and post-processing the results. Wright Laboratory's Armament Directorate (WL/MNSH branch) at Eglin AFB has used a beta J-MASS system extensively to develop working three degree-of-freedom (DOF) and six DOF models of generic air-to-surface and air-to-air munit ions to support technology development efforts. The munitions models were divided into objects similar to a real world missile including the umbilical, warhead, motor, fuse, seeker, kinematics and aerodynamics. Using J-MASS in the development process was both faster and less costly than tradition methodologies. The original three DOF Eglin air-to-air missile was converted to a surface-to-air (SAM) model at MDA by adding a booster object and command guidance. Since the original model was developed using the J-MASS system, most of the changes needed were in the attributes only. This model is unclassified for demonstration purposes. WL/MNSH has also developed six DOF munitions models based on similar model components. The models are stored in the user's modeling library or the J-MASS Model Simulation Reuse Library (MSRL), The MSRL will contain a variety of verified/validated models (or references to classified models) and model components available to J-MASS users.
