Drone Control and Data Retrieval System (DCDRS). Preliminary Design Study Final Report. Volume II. System Design. Part XII. Reliability and Maintainability Allocations, Assessments, and Analysis Report.
A reliability, maintainability, and availability RMA analysis of the various DCDRS configurations has been accomplished. Twenty-two configurationstate combinations were studied. The configurations refer to 1 The various RCCs, RPV control centers, that is, the maximum, intermediate, basic and minimum capability versions, 2 The different RPVs, i.e., strike and relay 3 The two airborne RCCs intermediate and basic configurations 4 The Runway, Launch, and Recovery Units and 5 The total system. Also included in the analysis was a complete RPV including the non-DCDRS elements, which was used in studying the effectiveness of DCDRS. The states refer to conditions of the various configurations with regard to equipments operating or failed. The full-up state requires all equipments, and only actual redundancy is considered. The mission critical state considers only those equipments essential to complete mission success, and achieves virtual redundancy in all areas where multiple equipments exist.
