本文介绍一种满足陆军下一代旋翼飞机(LHX)功能需求的先进航空电子结构的开发方法。文中对任务要求作了概括说明,以明确LHX系统的功能划分,接着简要介绍了每一个分系统,讨论了处理算法要求,以便定量确定航空电子结构的性能要求。本文还介绍了一个多处理机,多传感器结构,包括宽带传感器,窄带传感器、处理结构和互连分层。这种分层可以在LHX限定的功耗,体积和重量限度内提供系统灵活性,可靠性,可用性和容错能力。
This article describes an advanced avionics development methodology that meets the needs of the Army’s next-generation rotorcraft (LHX). In this paper, the task requirements are summarized to clarify the functional division of the LHX system, followed by a brief introduction of each subsystem, the processing algorithm requirements are discussed in order to quantitatively determine the performance requirements of the avionics structure. This article also describes a multiprocessor, multisensor architecture that includes a wideband sensor, a narrow band sensor, a processing architecture, and an interconnect hierarchy. This layering provides system flexibility, reliability, availability, and fault tolerance within the limits of power, size and weight limited by LHX.
