2. ARIES Integrated IFE Chamber Analysis and Assessment Research -- Goals • Analyze and asses integrated and self-consistent IFE chamber concepts; • Identify the design/operation window for each promising concept; • Identify present data base and need extrapolations for each promising concept; • Identify high-leverage items for R&D. • Note: the research is not aimed at developing a point design.

3. ARIES Integrated IFE Chamber Analysis and Assessment Research -- Goals • The research is not aimed at developing a point design. The goal is to understand trade-offs and identify design windows. • To guide the R&D, we need to be clear on what are high-leverage R&D items: • Not only What data is missing and what are shortcomings of present tools if any? • For incomplete database, what is being assumed and why? • For incomplete database, what is the acceptable range of data? Would it make a difference to zeroth order, i.e., does it make or break the concept? • Scientific Credibility is the key.

4. ARIES Integrated IFE Chamber Analysis and Assessment Research -- Approach • To make progress, we divide the activity based on three classes of chambers: • Dry wall chambers; • Solid wall chambers protected with a “sacrificial zone” (such liquid films); • Thick liquid walls. • These classes of chambers will be researched in series with the entire team focusing on the task in hand. • We choose a minimum of two and a maximum of four target designs for analysis. For a start, we choose designs that are already produced in detail. (5 classes of target are identified.)
