Electromagnetic vulnerability (EMV) testing is typically performed on aircraft using a standard method where the aircraft is directly radiated by an antenna, with no mode-stirring. Since a standing wave pattern will cause peaks and nulls in the field inside the aircraft, many antenna aspect angles should be used to assure that all equipment on board the aircraft is exposed to the appropriate field. However, this is very time consuming and often not feasible. As a result, some equipment on the aircraft may not be exposed to the intended field level. Using mode-stirred techniques during EMV testing will provide improvement in field distribution throughout the aircraft so that the need to use several aspect angles would be eliminated, and a more controlled and thorough test would result. This study was performed to demonstrate this, by comparing cable coupling and field level measurements on a P-3 and an E-2C during EMV testing using both the standard method and mode-stirring.
电磁脆弱性(EMV)测试通常在飞机上进行,使用标准方法,飞机由天线直接辐射,没有模式搅拌。由于驻波模式会在飞机内部产生波峰和波谷,因此应使用许多天线的角度,以确保飞机上的所有设备都暴露在适当的波场中。然而,这是非常耗时的,而且通常是不可行的。因此,飞机上的一些设备可能无法暴露在预期的现场水平。在EMV测试中使用模式搅拌技术将改善整个飞机的场分布,从而消除了使用几个俯角的需要,从而实现更可控、更彻底的测试。本研究通过比较电缆耦合和P-3和E-2C在EMV测试期间使用标准方法和模式搅拌的现场液位测量结果来证明这一点。

Flight critical system architects are increasingly integrating aircraft control and management functionality. This functional integration increases performance and cost of ownership requirements on the communication pathways. Optical signal transmission is an attractive approach to satisfying these system requirements. Investigations and demonstrations of optical signaling are needed to validate applicability of fiber based communication systems to the new system architecture performance and cost requirements. Honeywell's activities associated with the Fly-By-Light Advanced System Hardware (FLASH) program have produced a system including key optical interface elements and accomplished preliminary demonstrations needed to validate flexible, optical based aircraft control and avionic systems. The Honeywell Primary Flight Control System (PFCS) included Active Hand Controllers (AHCs), Primary Flight Control Computers (PFCCs) and smart actuation subsystem elements interfaced through various optical implementations and communication protocols. These successful implementations and demonstrations provide an excellent baseline for the processes, tools and materials required to make Fly-by-Light avionic systems marketable.

Using information management to integrate smart vehicle subsystems 利用信息管理集成智能汽车子系统
Pub Date : 1996-10-27 DOI: 10.1109/DASC.1996.559172
M. Silbert
There are many subsystems on-board the modern military aircraft to provide enhanced capability and to enable the pilot to better perform his mission. Unfortunately, most of these subsystems each require some management by the pilot in the form of monitoring gauges, displays or indicators. As a result, pilot workload often increases since the pilot must monitor the health of his vehicle in addition to performing his mission. But the pilot should be focused on his mission, not on the aircraft itself. There are simply too many potential distractions from vehicle status indicators and gauges. Vehicle management systems need to be developed to provide more autonomy in the management of aircraft subsystems. Furthermore, when a subsystem does fail, it is left to the pilot to determine both how the failure will affect other subsystems and more importantly, how the failure will affect his ability to carry out his mission. This paper addresses the issue of how to reduce the pilot's management of aircraft subsystems by developing an integrated vehicle manager that relies on various smart subsystems technologies.
现代军用飞机上有许多子系统,以提供增强的能力,并使飞行员能够更好地执行任务。不幸的是,这些子系统中的大多数都需要飞行员以监测仪表、显示器或指示器的形式进行一些管理。因此,飞行员的工作量往往增加,因为飞行员除了执行任务外,还必须监测其车辆的健康状况。但飞行员应该专注于他的任务,而不是飞机本身。车辆状态指示灯和仪表有太多潜在的干扰因素。需要开发车辆管理系统,以在飞机子系统的管理中提供更多的自主权。此外,当一个子系统发生故障时,留给飞行员来确定故障将如何影响其他子系统,更重要的是,故障将如何影响他执行任务的能力。本文通过开发一种基于各种智能子系统技术的综合飞行器管理器,解决了如何减少飞行员对飞机子系统的管理问题。

During an era of continually declining defense budgets, the defense establishment is being required to maintain or expand existing capabilities while expending fewer resources. In conjunction with this austerity dictate, our weapons platforms and their associated systems are being required to expand their capabilities in ways never envisioned during their initial designs. The B-52 bomber is a consummate example of this capabilities extension. As the lineage of this weapons platform now stretches into its fifth decade of service, the aircraft and its systems, upgraded many times over its life span, must maintain the capabilities of its critical mission with improved reliability and at reduced life-cycle costs, while providing the ability to add new functionality and adapt to ongoing technology improvements. The B-52's Avionics Computer Units (ACUs), the AP-1O1C Mission Computers, illustrate many of the problems of the aging military electronics being utilized to support today's requirements.
在国防预算不断下降的时代,国防机构被要求在消耗更少资源的同时保持或扩大现有能力。与这种紧缩要求相结合,我们的武器平台及其相关系统被要求以最初设计时从未设想过的方式扩展其能力。B-52轰炸机是这种能力扩展的完美例子。随着该武器平台的发展,飞机及其系统在其生命周期内进行了多次升级,必须以更高的可靠性和更低的生命周期成本保持其关键任务的能力,同时提供增加新功能和适应持续技术改进的能力。B-52的航空电子计算机单元(acu), ap - 101c任务计算机,说明了用于支持当今需求的老化军事电子设备的许多问题。

Aircraft collision avoidance based on GPS position broadcasts 基于GPS位置广播的飞机避碰
Pub Date : 1996-10-27 DOI: 10.1109/DASC.1996.559189
R. Gazit, J. Powell
The current airborne collision avoidance system provides pilots with approximate information on the relative location of nearby traffic, and with recommended escape maneuvers in the vertical plane. It relies on range measurements, and suffers from high false alarm rate. This paper studies a new collision avoidance system, which is based on periodic broadcasts of aircraft position as derived by an on-board GPS receiver. Several collision detection algorithms were evaluated by using a Monte Carlo simulation of random encounters in a free-flight environment. The algorithm selected uses the miss distance vector for both detection and avoidance. This approach can significantly improve the effectiveness of the current collision avoidance system, while lowering both the probability of false alarm and the probability of late alarm.

User portability in open systems 开放系统中的用户可移植性
Pub Date : 1996-10-27 DOI: 10.1109/DASC.1996.559160
L. Avery
The open systems concept in the design of computer-based systems has become accepted as a method for developing cost-effective systems. One goal of open systems design within the U.S. Department of Defense is user portability. User portability can be described as the ability of users to move from one application or system to another, with minimal difficulties. It is accomplished by applying style guide principles and user interface specifications concurrently with user-centered design. The key factor for integrating these into the design process is the use of human factors engineering.

A methodology for cost-effective software fault tolerance for mission-critical systems 为关键任务系统提供一种经济有效的软件容错方法

As computing capabilities continue to advance, there will be a concurrent rise in the number of both hardware and software faults. These will be caused by the greater volume of more complex software, by the increased number of untested software states, and by more incidents of hardware/software interaction faults as a result of increased hardware speed and density. The traditional software implemented fault tolerance approaches have been successfully utilized in life-critical systems, such as digital flight controls, where their additional costs can be easily justified. Examples include N-Version Programming and Recovery Block approaches. However, there is still a need for dependable computing for mission-critical applications as well. Often, these traditional techniques are avoided for mission-critical systems due to the difficulty in justifying their extra upfront development cost. We provide an alternative for the high "sunk cost" of traditional software fault tolerance techniques. The methodology, called Data Fusion Integrity Processes (DFIPs), is a simple, yet effective technique for mission critical systems. In addition, the approach establishes a framework from which other costlier, more extensive traditional techniques can be added. We present details of the DFIP methodology and a DFIP framework for Ada programs. We also briefly discuss development of a DFIP code generation system which exploits Java that will enable users to quickly build a DFIP framework in Ada, and select reusable DFIP component methods.
随着计算能力的不断提高,硬件和软件故障的数量将同时增加。这些将由更复杂的软件的更大容量、未经测试的软件状态数量的增加以及由于硬件速度和密度的增加而导致的硬件/软件交互错误的更多事件引起。传统的软件实现容错方法已经成功地应用于生命关键系统,如数字飞行控制,在这些系统中,它们的额外成本很容易得到证明。例子包括n版本编程和恢复块方法。然而,对于关键任务应用程序,仍然需要可靠的计算。通常,由于难以证明其额外的前期开发成本,这些传统技术被避免用于关键任务系统。我们为传统软件容错技术的高“沉没成本”提供了一种替代方案。这种方法被称为数据融合完整性过程(DFIPs),是一种简单而有效的关键任务系统技术。此外,该方法还建立了一个框架,可以从中添加其他更昂贵、更广泛的传统技术。我们详细介绍了DFIP方法和Ada程序的DFIP框架。我们还简要讨论了DFIP代码生成系统的开发,该系统利用Java使用户能够在Ada中快速构建DFIP框架,并选择可重用的DFIP组件方法。

There are key technology and acquisition issues of prime importance to the US Army as it develops plans to provision warfighters with capabilities that harness computing power to enhance combat power in the next century. This harnessing of computing power is the crux of the Army's "digitization" efforts. A critical component of this "digitization" provisioning will be a dependence upon industry standards and commercial best practice in system engineering and development, e.g., Acquisition Reform. This paper discusses issues related to the Department of Defense's (DOD) acquisition reform initiatives and how some of the challenges associated with Army "digitization" under these initiatives can be overcome through open architecture definitions. The paper also presents strategies on how the DOD and industry can help each other transition to the new acquisition and business environments precipitated by these initiatives.

Honeywell FLASH fiber optic motherboard evaluations 霍尼韦尔FLASH光纤主板评估
Pub Date : 1996-10-27 DOI: 10.1109/DASC.1996.559153
K. Stange
The use of fiber optic data transmission media can make significant contributions in achieving increasing performance and reduced life cycle cost requirement placed on commercial and military transport aircraft. For complete end-to-end fiber optic transmission, photonics technologies and techniques need to be understood and applied internally to the aircraft line replaceable units (LRUs) as well as externally on the interconnecting aircraft cable plant. During a portion of the Honeywell contribution to Task 2A on the Fly-by-Light Advanced System Hardware (FLASH) program, evaluations were done on a fiber optic transmission media implementation internal to a Primary Flight Control Computer (PFCC). The PFCC internal fiber optic transmission media implementation included a fiber optic backplane, an optical card-edge connector, and an optical source/detector coupler/installation. The performance of these optical media components was evaluated over typical aircraft environmental stresses of temperature, vibration, and humidity. These optical media components represent key technologies to the complete end-to-end fiber optic transmission capability on commercial and military transport aircraft. The evaluations and technical readiness assessments of these technologies will enable better perspectives on productization of fly-by-light systems requiring their utilizations.
使用光纤数据传输介质可以在提高商用和军用运输机的性能和降低寿命周期成本要求方面作出重大贡献。为了实现完整的端到端光纤传输,需要了解光子学技术和技术,并将其内部应用于飞机线路可更换单元(lru),以及外部应用于互连飞机电缆工厂。在霍尼韦尔对Fly-by-Light先进系统硬件(FLASH)项目任务2A的部分贡献中,对主飞行控制计算机(PFCC)内部的光纤传输介质实现进行了评估。PFCC内部光纤传输介质实现包括光纤背板、光卡边缘连接器和光源/检测器耦合器/安装。这些光学介质组件的性能在典型的飞机环境应力的温度,振动和湿度进行了评估。这些光介质组件代表了商用和军用运输机端到端光纤传输能力的关键技术。对这些技术的评价和技术准备情况评估将使人们能够更好地了解需要利用这些技术的光控飞行系统的产品化。

For complete end-to-end fiber optic transmission, photonics technologies and techniques need to be understood and applied internally to the aircraft line replaceable units (LRUs) as well as externally on the interconnecting aircraft cable plant. During a portion of the Honeywell contribution to Task 2A on the Fly-by-Light Advanced System Hardware (FLASH) program, evaluations were done on a fiber optic transmission media implementation internal to a Primary Flight Control Computer (PFCC). The PFCC internal fiber optic transmission media implementation included a fiber optic backplane, an optical card-edge connector, and an optical source/detector coupler/installation. The performance of these optical media components was evaluated over typical aircraft environmental stresses of temperature, vibration, and humidity. These optical media components represent key technologies to the complete end-to-end fiber optic transmission capability on commercial and military transport aircraft.
