Best Practice : Integrated Flight Simulation
Raytheon Missile Systems Company (RMSC) developed an Integrated Flight Simulation (IFS) which runs performance analysis, requirements verification, design development, pre-flight analysis, and post-flight analysis on simulated missiles. This Six Degrees of Freedom (6DOF), imaging IFS uses detailed models of sensors, target geometry, tracker algorithms, and other simulation requirements to accurately emulate the missile.
RMSC’s simulation development process started with the Missile Object-oriented Simulation Tool (MOST), an unclassified generic simulation program written in C++. The company and several of its customers worked together to develop IFS and MOST, and are now well versed in the reusable user interface that drives these simulations. MOST can provide future programs with a mature 6DOF structure for airborne vehicles as well as generic missile models that can be used in trade studies; Monte Carlo simulations; missile phasing capability assessment; and digital model timing control simulations.
Design and validation simulations are a proven, low cost tool which provide users with an alternative to actual tests. RMSC designed the IFS structure to be easily adaptable to changing simulation roles, user needs, and requirements when simulating airborne vehicles that require 6DOF. IFS planning, development, and implementation enabled RMSC to achieve this adaptability in the AIM-9X program.
