US Air Force relies on computer graphics to evaluate combataircraft performance

The use of computer graphics analysis and other powerful tools to evaluate jet aircraft performance at the US Air Force Flight Test Center, Edwards Air Force Base in California, is described. As many as 14 test versions of the same aircraft model are instrumented with sophisticated sensors to allow flight-test data to be recorded on tape. The tape-recorded data points are used by flight-test engineers to review each aircraft's actual in-flight performance. It was found that computer-generated graphic displays of complicated physical relationships make the job of interpreting aircraft performance data considerably less difficult. The use of interactive graphics to boost productivity is also discussed     

极区航空导航综述

极区导航技术是保证极区安全可靠飞行的必要手段,通过对极区导航影响因素的分析,阐述了极区导航发展的早期面临的两个主要问题:地理经线快速收敛于极点导致无可用的航向参考线和缺少实用的可替代磁罗盘的航向跟踪测量设备。为解决上述两大难题,极区导航经历了"早期时代"、"翡翠时代"和"自动化时代"三个发展时期,最终确定格网和陀螺是当时也是目前极区导航的最佳方案。目前,惯性导航系统是极区导航的核心设备,为此着重分析了适合极区用的极圈惯导编排方案、横向惯导编排方案和格网惯导编排方案,并介绍了三种编排方案的优缺点。最后,对全文进行了总结和展望,旨在加强研究者的交流,进一步促进国内极区导航技术的发展。

基于Agent的海军航空兵突防作战仿真研究

航空兵作战中的突防过程决定着作战任务能否顺利完成。在研究海军航空兵突防作战过程的特点的基础上,建立了基于多Agent的作战仿真模型,分析了Agent间的通信过程及指挥所Agent的推理决策过程,并构建了相应的模型。该研究为以后进一步开展多Agent系统的研究打下了基础,对海军航空兵作战仿真研究也具有一定指导意义。     

某航空兵场站机载弹药保障仿真研究

航空兵场站机载弹药保障的要素和环节众多,且相互影响、相互制约,通常采用计算机仿真对这类系统效能进行定量评估。本文对某航空兵场站机载弹药保障的力量构成、保障过程和特点进行了分析,并将其抽象为一个离散事件系统,建立了涵盖任务下达与执行、保障对象、保障资源以及保障过程等要素的建制单位离散事件仿真模型,并在此基础上开发了仿真系统。应用表明,该仿真模型运行正确、可靠,为某航空兵场站机载弹药保障效能评估提供了有力的分析工具。     

Development of an operational fitness test for the Royal Air Force

Since 2002, the Royal Air Force (RAF) has been working towards developing role-related physical tests for use as an operational fitness test (OFT). The purpose of this study was to establish reliability of the OFT (comprising four tests), investigate gym-based tests as predictors of performance and establish performance standards. Fifty-eight RAF personnel performed the OFT on three occasions. A separate cohort carried out fitness and anthropometric tests before performing the OFT, by way of establishing performance predictors. Documented evidence and views of an expert panel were used to determine OFT standards. Reliability ranged from moderate to good for three tests, with one test (Dig) showing poor reliability. The 95% limits of agreement for the prediction models ranged from good to poor (6.7–34.2%). The prediction models were not sufficiently accurate to estimate confidently OFT performance, but could be used as a guide to quantify likely outcome and training needs.
