摘要

The National Research Council of Canada (NRC) and Honeywell Aerospace (EMS Aviation Technologies Inc. Canada) completed prototype testing of its helicopter Satellite Communications (SATCOM, Aspire 200 Series) system for certification assessment. As the NRC Bell 412 is experimental (fly-by-wire control system, upgraded engines and displays), the Honeywell HSD-400i system payload represented a surrogate integration on a standard Bell civil utility transport helicopter. Following NRC's airworthiness clearance, ground testing was completed with data collected encompassing aircraft performance, SATCOM performance, and radio frequency (RF) energy surveys. There was no negative influence of the integration or associated testing on aircraft engine or transmission performance. NRC aircraft radio frequency measurements indicated safe SATCOM RF energy outputs. Externally, higher RF energy output occurred in the aircraft's first quadrant (i.e.; nose and right of nose). Internally, higher RF energy occurred in the aircraft's cockpit decreasing towards the aft-cabin. Honeywell measurements of throughput, bandwidth, and linking via real time data analysis indicated acceptable SATCOM performance. Data rates for SATCOM reception and transmission were analyzed where worst case connectivity was assessed to be 25% less than those for best and baseline case rates. Overall, analyses by Honeywell engineers indicated that acceptable performance is expected for Aspire-200 systems integrated into transport utility class helicopters such as the NRC Bell 412 providing knowledge for Honeywell's substantiation of future SATCOM product Special Type Certificate applications.

Canada）完成了其直升机卫星通信（SATCOM，Aspire 200系列）系统的原型测试，用于认证评估。由于NRC铃412是实验性的（逐线控系统，升级发动机和显示器），霍尼韦尔HSD-400I系统有效载荷代表了标准钟线公用公用事业运输直升机上的代理整合。在NRC的适航许可之后，完成地面测试，随着包括飞机性能，SATCOM性能和射频（RF）能量调查的数据完成。在飞机发动机或传输性能上没有积分或相关测试没有负面影响。 NRC飞机射频测量指示安全的SATCOM RF能量输出。外部，飞机的第一象限（即;鼻子和鼻子右侧）发生的更高的RF能量输出。在内部，飞机的驾驶舱内发生更高的RF能量朝向船尾舱。蜂窝吞吐量，带宽和通过实时数据分析的霍尼韦尔测量表明了可接受的卫星性能。分析了SATCOM接收和传输的数据速率，其中评估最差的情况是比最佳和基线案例率小于25％。总体而言，霍尼韦尔工程师的分析表明，预期可接受的性能预计将Aspire-200系统集成到运输效用等级直升机等NRC贝尔412，为霍尼韦尔未来的卫星产品特殊类型证书应用提供了知识。
