现代作战飞机所用的先进电子设备愈来愈多,飞机的性能明显提高,但在飞机的初始成本、维护工作负担与飞机可用性等方面也付出了重大代价。因此,在开发、设计航空电子系统时,现在开始同等强调性能、经济上的可承受性、可维护性以及可靠性这几个方面。另一方面,微电子技术在速度与密度方面所取得的最新进展使得现在有可能研制强有力的、价格上能承受得了的航空电子结构单元,即处理器、存储器与宽带数据总线等。利用这些单元形成的先进结构,加上高度灵活的软件,就能更加充分利用信息综合与自动化技术。采用这种方法,就有可能在提高航空电子系统可用性、减轻驾驶员工作负担、提高武器系统生存力与可支援性方面取得明显成效。为了满足不断增长的任务要求,需要尽早将这些系统综合技术应用到实际中去,但必须确保所设想的方案与标准是成熟的。方法应通过确认试验,以免失策而导至成本过高.美国空军确定通过“宝石柱”计划在预研阶段使先进的航空电子系统结构方法、系统单元和可能需要的系统标准达到所需的成熟程度。在赖特航空电子实验室范围内,也就是从这个计划开始,把系统综合技术确立为一个独立的学科。本文介绍曾在赖特航空电子实验室内进行的“宝石柱”计划,说明系统综合对提高作战效能的影?
The increasing use of sophisticated electronic equipment in modern combat aircraft has led to significant improvements in the performance of aircraft, but significant costs have also been incurred in terms of the initial cost of the aircraft, the maintenance of the workload and the availability of the aircraft. As a result, when developing and designing avionics systems, the emphasis is now on equal emphasis on performance, affordability, maintainability, and reliability. On the other hand, recent advances in microelectronic technology in terms of speed and density have made it possible now to develop robust, affordable avionics units, namely processors, memories and broadband data buses. Leveraging the advanced structure these units form, coupled with highly flexible software, make the most of information synthesis and automation technology. With this approach, it is possible to achieve significant results in improving the availability of avionics systems, reducing the driver’s workload, and improving the viability and supportability of weapon systems. In order to meet the evolving mandates, these systems integration technologies need to be put into practice as soon as possible, but it is important to ensure that the scenarios and standards envisioned are mature. Methods should be confirmed by the test, so as to avoid any oversight cost overruns. The United States Air Force has decided to bring the advanced avionics system architecture approach, system elements and system standards that may be required to achieve the required level of sophistication through the Precious Stones program at the pre-research stage. Within the context of Wright Avionics Labs, that is, from the beginning of this project, system integration has been established as an independent discipline. This article describes the “gemstones” program that was conducted at Wright’s Avionics Lab to illustrate the impact of system synthesis on improving operational effectiveness.
