Multidisciplinary Virtual Simulation Environment for Missile Interception

The overall objective of this effort is to develop a multidisciplinary virtual environment for modeling and simulation of the processes undertaken in typical missile interception program. In the proposed technology, computational modules for external missile aerodynamics, six-degrees-of-freedom, guidance and control, finite-element structure dynamics, and fluid-structure interaction will be coupled together as a single virtual simulation environment. The proposed environment will be capable of simulating the missile interception processes including the effects of thrust generation, missile aerodynamics, missile staging, fin/canard deployment, sub-munitions dispensing and interfacing with guidance and control systems. The proposed development will leverage existing technologies for fluid/structure and 6DOF modeling. The Phase I effort will focus on the development of integration modules for coupling control modules to the simulation environment. Phase I effort will demonstrate the feasibility of the proposed technology for missile interception simulation by conducting a closed-loop control missile pitch maneuver simulation, and will define the complete requirements for developing the simulation environment In Phase II, The interface modules will be developed and the simulation environment will be demonstrated and validated. A finite-element structure dynamics module will be integrated with the environment with capabilities for MATLAB/Simulink control to enable simulation of typical and complete missile interception programs.
