Theater Level Effectiveness Analysis for Advanced Materials and Structures
Abstract
This is our final technical report, the purpose of which is to demonstrate our ability to estimate and compare the contributions of advanced materials and structures to effectiveness, at the theater level. A Middle East scenario in the 2000-2010 timeframe was chosen for this demonstration. A notional advanced fighter was used for the example. Two advanced materials were selected for comparison - a conventional polymer-based composite for the aircraft skin which provides weight savings, and a high temperature ceramic for the engine hot section which allows increases in engine turbine inlet temperature. We also provided results for increased tank survivability, to demonstrate the flexibility of the model in assessing a range of weapons system. By varying these characteristics against the base case, a set of parametric curves were developed which plot change in effectiveness vs. change in characteristic. By using these curves, the change in campaign effectiveness produced by each of the three materials was determined. A break even cost vs. change in material curve was then produced to enable estimates to be made of when a development program of stated risk should be undertaken compared to simply buying more aircraft of the stated characteristics. In addition to this report, we are delivering the parametric curves developed for this demonstration on magnetic media. These will permit users at DARPA to see how easy it is to have effectiveness information available to them for the purpose of comparing the impact of various advanced materials and structures on campaign effectiveness.
