Common Launch Acceptability Region Task Group

This paper presents a brief overview of the Common Launch Acceptability Region Approach (CLARA) problem and the history of efforts within the Air Force and SAE to address it. An SAE Task Group has produced top level requirements and a proposed CLAR Methodology consisting of three components (Truth Model, Coefficient Generator and LAR Generator) that provides a solution to the multiple LAR implementation problem. This proposed CLAR methodology fulfills the key requirement of a LAR algorithm that is to be common to all applications and allows updates via tables of coefficients requiring the validation of only those coefficients and not the algorithm. This paper also presents the status of trade studies being conducted by the CLARA TG on mathematical algorithms required to implement the methodology. A key step in these trade studies is development of the appropriate metrics and analysis tools with which to judge alternative algorithms.
