DEVELOPMENT OF THE MISSILE COMPONENT LIBRARY (MCLib) FOR TACTICAL MISSILE SIMULATION

摘要

The Army's Simulation and Modeling for Acquisition, Requirements and Training (SMART) approach to Simulation Based Acquisition (SBA) - as mandated by the Department of the Army - continues to place ever-higher demands on simulation technology as applied to tactical missile procurement. These demands come in terms of simulation level of fidelity, speed of execution, reliability, validity, and efficiency of development. The Aviation and Missile Research, Development, and Engineering Center's (AMRDEC) System Simulation and Development Directorate (SS&DD) established the Common Simulation Framework (CSF) in 1999 to help answer the simulation development demands in both the government and prime contractor domains. Use of the CSF as a simulation development tool has proved successful on a number of tactical missile programs in the recent past and it continues to find acceptance among simulation developers and management. As a further step in pursuing uniformity and consistency of simulation design for tactical missiles, SS&DD has established the Missile Component Library (MCLib) for tactical missile simulation and modeling. MCLib builds on the CSF's object oriented design approach to provide a set of CSF-compatible missile component and environment models that allow a high fidelity missile simulation to be realized with minimum development time. MCLib is divided into two areas: the 6-Degree of Freedom (6-DoF) Propulsion Aerodynamics Controls and Kinematics Model (6-PACK) and the Modular Object-Oriented Sensor Evaluation Suite (MOSES). At its core, 6-PACK contains the fundamental models that comprise a typical 6-DoF missile simulation with defined base classes and interfaces. MOSES is a suite of sensor models that provides a generic driver for the 6-PACK model within MCLib. MOSES also provides a plug-and-play sensor evaluation capability for performance analysis and trade studies. MCLib is one component in an Integrated Flight Simulation (IFS) with the other components being re-hosted Tactical Flight Code and a scene generator capability suitable for the sensor of interest. The IFS concept maximizes the use of modeling and simulation for system, software, and algorithm design; analysis; flight test support; and performance assessment of a missile system.
