Electronic Master Monitor and Advisory Display System. Operation Functions Report

摘要

The development of non-mission-related status information is one area of rotary wing instrumentation which has not kept pace with the state-of-art. This includes raw data, discrete and summary status information related to the engine, transmission, rotor, fuel, hydraulic and electrical subsystems. This report describes the results of work done under Task I of contract No. DAAK80-79-C-0270, to establish basic system operating requirements for an Electronic Master Monitor and Advisory Display System (EMMADS). This system is being developed for use on U.S. Army helicopters to reduce crew workload by assuming responsibility for tasks associated with subsystem status monitoring. EMMADS will integrate all instrumentation normally dedicated to subsystem status monitoring (e.g. all pressures, temperatures, etc.) plus caution/warning/advisory indicators, into a computer controlled, solid state system. It will detect, analyze and provide emergency checklists for any faults that it is programmed to monitor for in these subsystems. This report represents a tieing together of Task I and II to provide a baseline for defining the requirements of the feasibility demonstration hardware. In Task I, helicopters representing all operational helicopter categories (cargo, utility, scout, and attack) were identified and a signal analysis was done on each. While the EMMADS functions described in this report are applicable to all helicopter categories studied under Tasks I and II, specific examples used herein are all related to the CH-47C helicopter.
