Objective:  This subcommittee exists to promote and facilitate exchange of technical information; establish guides, procedures, and standards; affect coordination of research, exploratory development, advanced development, and engineering.  This subcommittee shall focus on solving problems of joint agency interest for airbreathing, rocket, missile, and spacecraft propulsion through robust, verifiable, and credible simulation in order to reduce acquisition time, total life-cycle cost, and risk.

MSS Mission Areas

The JANNAF 10th Modeling and Simulaton Subcommittee meeting covers: engineering models and simulations for virtual design; virtual tests; virtual operations; and virtual manufacturing of propulsion components/subsystems or of complete propulsion systems; systems integration of subsystems into an engine, motor or vehicle, and integration of the propulsion system with other systems; integrated health management (IHM) including M&S of IHM systems for diagnostics, failure modes, prognostic,  and corrective modes; and credibility assessments of models and simulations including verification,  validation, certification or accreditation, sensitivity-uncertainty analysis, measurement uncertainty, simulation uncertainty, and uncertainties in probabilistic risk assessment (PRA).

Mission Area I: Modeling and Simulation of Systems

Modeling and simulation analyses of missile, aircraft, and launch vehicle systems detailing the results of propulsion technology tradeoffs, technology parameter sensitivities, and technology payoff assessments as applied to vehicle level M&S are highly encouraged.

  • M&S of vehicle system technology trades for space launch systems, prompt strike platforms, long-range ballistic missiles, cruise missiles, and hypersonic cruise vehicles
  • Advances in the development of tools, models, and methods for vehicle-level modeling and simulation
  • Simulations, methods, and models to evaluate performance capabilities, cost, and reliability of systems
  • Vehicle and launch facility, weapon and weapon platform, propulsion system and test facility simulations, interactions, integration

Mission Area II: Virtual Engineering

Mr. Gary C. Prybyla, NSWC/Indian Head
Telephone:  (301) 744-1473

Virtual engineering encompasses the set of tools used to help develop, design, test, analyze, and screen systems, components, and concept for simulation-based acquisition. Virtual engineering uses rapid synthesis and simulation tools, which include traditional deterministic and non-deterministic simulation methods and non-traditional or “soft computing” methods, including fuzzy logic, neural networks, and genetic algorithms. The goal of virtual engineering is the application of high-credibility models for accurate analysis and rapid design-space evaluation, leading to increases in functionality at reduced cost.

  • Design, integration, manufacturing, and testing—tools and techniques.
  • Engineering decision support. Optimization, cost analysis, scheduling, and knowledge-based tools—integration into the engineering process.
  • Advances in the development of models and methods for component modeling and simulation to aid design.

Mission Area III: Integrated Health Management

Mr. R. Scott Hyde, ATK Aerospace Propulsion Systems/Brigham City  
Telephone:  (435) 863-6307

Integrated Health Management promotes advancement and development of industry practices for IHM of propulsion systems within a “system of systems” environment. IHM includes methods and tools for: data management and mining; integrated command and control; sensors; diagnostics; and prognostics. These tools enable making redline and contingency decisions using knowledge-based expert systems, model-based diagnostic and reasoning, fault models, neural networks, fuzzy logic, genetic and evolutionary algorithms, and life-cycle analysis.

  • Data Management and Mining: Advances in data mining, machine learning, and statistics with applications to verification and validation of data, prognosis and diagnosis of system health.
  • Integrated Communications, Command and Control: theory, test beds, and demonstrations.
  • Sensor Systems: measurement technology, smart sensors, test beds, sensor fidelity
  • Diagnostic Systems: theory, simulations, and demonstrations of diagnosis of current state of health of propulsion and vehicle system.
  • Prognostic Systems: theory, simulations, and demonstrations of prognosis of future state of health of propulsion and vehicle system; mitigation of, and recovery from, degraded system health to enable successful missions

Mission Area IV: Simulation Credibility: Uncertainty, Verification, Validation, and Risk

The credibility of digital and analog simulations is a major issue for incorporating simulation tools and data into a technology-development program, for conducting simulation-based acquisition, for assessing system reliability to assure human safety and/or mission success, and for identifying and assessing risks in complex, technological systems. Simulation credibility includes assessment and management of computer simulation uncertainty, sensitivity-uncertainty analysis, experimental uncertainty, modeling uncertainty, verification and validation (V and V) of simulation models and of simulations, and risk assessment. Abstracts are solicited on unusual or specific solutions, on novel approaches, and on technological advances.

  • Uncertainty assessment, sensitivity analysis, quantification, for experiments and simulations
  • Validation of models and verification of simulations
  • Propagation of uncertainty
  • Communication, management of uncertainty; risk assessment and management
  • Recommendations for guidelines, procedures, or standards.
