Preliminary Design of an Accident Information Retrieval System (AIRS).
Abstract
This report covers the phase I activity entitled Concept Investigation and phase II entitled Preliminary Design and System Analysis. The report details the analyses involving requirements, parameters, trade-offs, and definition of a recommended AIRS. The Phase I effort included the intense analysis of the airborne portion of the system since it is the most sensitive element in terms of size, weight, and cost. This included examination of the parameter and sensor requirements, survivability and software. Actual flight data was used to run a program on a large-scale computer to determine limits, accuracy, and sampling rate effects on flight data reconstruction and aircraft memory storage requirements. Phase II included a detailed preliminary design of the AIRS. A preliminary hardware concept was established and the essential features of the recommended concept are included. The recommended system was analyzed to determine performance, weight, size, cost, installation, survivability, reliability, data retrieval, maintenance and functional test factors. Results indicate that the current state of the art will allow an AIRS to be developed for installation on production UTTAS and AAH aircraft. The recommended system employs an all solid-state design including the mass data storage device. Factors of two or more improvements in size, weight, reliability, maintainability are indicated over current data recording systems. (Author)
