RNTS Mission Areas

Mission Area I: Thermal, Structural and Fluid Analysis and Modeling

Suggested topics for papers in this session include:

  • Development of constitutive relationships for thermo-structural modeling of heated composites
    • Model validation studies of derived relationships
    • Numerical implementation of methods into integrated code
  • Structural analysis of composites including presentation of model results and implications of constitutive modeling methods and failure criteria
  • Study of material thermal decomposition kinetics and role in material structural response
  • Study of pyrolysis gas evolution and chemical treatment of reaction rate dependency on composition in thermally decomposing zones and char layers
  • Charring-material ablation thermal model development of composite materials including porous media methods development and implementation (one and two dimensional)
  • Development of semi-empirical laboratory techniques used for determination of composite material thermal, structural, and porous media properties at temperature
  • Study of nozzle environment predictions as it pertains to interaction with ablative materials
    • Condensed phase augmentation of nozzle liner surface recession rates by chemical and/or mechanical removal mechanisms
    • Characterization of convective heat and mass transfer environments using boundary layer or Computational Fluid Dynamic (CFD) methods

 

Mission Area II: Nozzle Design, Test and Evaluation

  • Nozzle design, test, and evaluation areas of interest include Evaluation - Health monitoring for material aging and material characterization
  • Nozzle Design ‘lessons learned’
  • Test - performance based acceptance test/post-test evaluation and new, improved test methods
  • New materials characterization and fabrication, including constituent/composite material behavior throughout all phases of processing
  • In-process characterization techniques and instrumentation.
  • Assessment of the state-of-the-art, vision of the future, and research/development paths is requested

Papers addressing qualitative and quantitative goals relevant to technical, and system level challenges are specifically sought. Discussion of new technologies/materials and future expectations is also invited.

 

Mission Area III: Thrust Control

Specific topics of interest include nozzle designs that use active or passive control to achieve thrust control; weight, volume, size, and cost reduction techniques; component and system modeling and analysis, to include system performance benefits of thrust management control or thrust vector control; control techniques, to include control systems, control algorithms, actuation methods or mechanisms; thrust management control via pulsing, and motor extinguishment and re-ignition; pintle controlled nozzles; VAN (variable area nozzle) designs; nozzle designs that incorporate thrust vector control (exclusive of jet vane systems) as well as thrust level control; developments in jet vane/tab, moveable nozzle, hot gas valve, probe, fluid injection, or any other standard or novel TVC technologies; TVC appliations of micro-electromechanical systems (MEMS); and component and system test results.

 

Mission Area IV: Innovative Nozzle Materials

This session will include papers addressing nozzle cost and weight reduction techniques; low cost designs; the investigation and/or assessment of new/innovative materials to address weight reduction requirements.
