Objective: The JANNAF Propulsion Meetings (JPM) promote the exchange of technical information in the fields of missile, space, and gun propulsion. These meetings assemble scientists and engineers who are responsible for leading the research and engineering efforts on government-sponsored and government-performed programs in these areas for the purpose of sharing information and research results. the JPM meetings are part of a series of such meetings dating back to the late 1940s.

The main sessions cover current propulsion science and technology, propellants, and hardware relevant to government programs, comparative system performances, and technology advances which affect current and future propulsion systems. Technical sessions are conducted on solid, liquid, hybrid, and air-augmented rockets, ramjets, scramjets, combined-cycle engines, expendable turbine engines, and electric propulsion, as well as missile, space transportation, orbit transfer, satellite, and gun propulsion applications.

This area focuses on the use of Additive Manufacturing (AM) as an enabling technology from both an organizational and a systems perspective. Additive manufacturing is critical for reducing manufacturing time and cost to produce specific components for propulsion systems, and multiple JANNAF Subcommittees are addressing the specific application challenges within their areas. Affordability is a critical element for both government and commercial systems. New and innovative manufacturing techniques are working their way into mainstream manufacturing. Before additive manufacturing is widely accepted for general use, it is necessary to understand the technology well enough to proceed with a high level of confidence. This Mission Area emphasizes how the various JANNAF organizations are planning to address the challenges of integrating AM into propulsion systems. What are the synergies between the JANNAF organizations’ AM plans and the AM centers of excellence such as America Makes (as well as others)? How are the JANNAF organizations addressing the integration of AM hardware into existing or new systems? Other areas to consider are overall cost considerations and ROI when incorporating AM hardware into new systems.

Digital Engineering (DE) is an integrated digital approach that uses authoritative sources of system data and models as a continuum across disciplines to support lifecycle activities from concept through disposal. DE focuses on the application and integration of models and simulations to improve the development and support of systems. DE encompasses several areas within the propulsion, hypersonic, and munitions communities including: Model Based Engineering (MBE); Integrated Health Management (IHM); and Modeling and Simulation of System Autonomy. The JANNAF Propulsion Meeting is providing an opportunity for modeling and simulation advancements in support of the DE strategy be shared across the military services, NASA, and the industrial base. Papers are sought in DE initiatives in general and the DE initiatives in the following areas:

  1. Model-Based Engineering (MBE) encompasses the development of methodologies, codes, and model simulations to quantitatively evaluate and optimize propulsion, hypersonic, and munitions technologies across component, subsystem, and vehicle system levels. MBE includes Model Based Systems Engineering (MBSE), Computational Fluid Dynamics (CFD), Computer Aided Design (CAD), Computer Aided Manufacturing (CAM), Finite Element Modeling (FEM), Optical Design, and other modeling and simulation used in Digital Engineering. The integrated set of these models constitutes the system Digital Twin. The use of models complements traditional experiments during technology development with a goal of reducing technology development time and schedule, as well as use physics-based models to explore domains and behaviors that are particularly difficult or impossible to examine experimentally.
  2. Integrated Health Management (IHM) promotes advancement and development of technologies that support both Simulation Credibility and Digital Engineering efforts that are being pursued across many of the JANNAF Subcommittees. IHM technologies are focused on propulsion, hypersonic, and munitions systems within a “system of systems” environment that reduces maintenance and logistics costs, and increases reliability of these systems. IHM includes methods and tools for: data management and mining; integrated communications, command and control; diagnostics; prognostics, and integrated sensors and sensing systems. These Digital Engineering 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.
  3. Modeling and Simulation of System Autonomy encompasses the development of methodologies, codes, models, and simulations to evaluate, analyze, and optimize autonomous system capabilities. Autonomous systems include aircraft, ground vehicles, hypersonic vehicles, launch vehicles, spacecraft, submarines, and sea surface ships. Modeling and Simulation of System Autonomy addresses the modeling and simulation of artificial intelligence (AI) algorithms, the integration of AI algorithms, simulation environments including the interaction of algorithms with system hardware, verification and validation of non- deterministic algorithms, and determination of operational bounds of autonomous systems. The use of modeling and simulations of autonomous systems to determine their responses and operational bounds is also a crucial Digital Engineering technology area.

Digital Engineering is based on having credible models and simulations of the system. The credibility of digital 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 quantification of simulation uncertainty, sensitivity-uncertainty analysis, experimental uncertainty, physical model validation, simulation verification and validation, and risk assessment. Papers are solicited on efforts and guidance on simulation credibility for unit, benchmark, subsystem, and system problems related to the following topics:

  • Uncertainty sources and sensitivity analysis
  • Propagation, quantification, and management of uncertainty
  • Simulation verification
  • Model validation
  • Simulation credibility assessment
