摘要

传统上,导弹系统飞行试验的实时测试数据是通过无线电遥测技术获取的。虽然遥测数据链接是一项成熟的技术,但在设计这种类型的仪器系统时仍然需要注意。遥测数据链的电气、机械和空气动力学干扰必须在测试车辆的硬件设计中仔细考虑。测试环境、范围条件和复杂的地面接收和数据减少站的支持都增加了无线电遥测数据采集的复杂性和成本。此外,许多武器系统设计从制导到“智能”再到“卓越”的演变,大大增加了获取和跟踪自主测试飞行器的难度(特别是那些需要同时在空中进行多架测试飞行器的测试项目)。本文介绍了一种低成本替代遥测飞行试验数据采集的设计和测试;机载高重力冲击生存飞行数据记录仪(FDR)。

High G Impact Resistant Digital Data Recorder For Missile Flight Testing
Traditionally, real time test data from flight testing of missile systems is acquired via radio telemetry. Although telemetry data linking is a well established technology, care is still required when designing this type of instrumentation system. Electrical, mechanical and aerodynamic interferences of the telemetry data link must be carefully considered as the hardware is designed into the test vehicle. Test environments, range conditions and support of elaborate ground based receiving and data reduction stations all add to the complexity and cost of radio telemetry data acquisition. In addition, evolution of many weapon system designs from guided to "smart" to "brilliant" has greatly increased the difficulty in acquiring and tracking an autonomous test vehicle (especially those test programs requiring multiple test vehicles in the air simultaneously). This paper presents the design and testing of a low cost alternative to telemetry based flight test data acquisition; an onboard high G impact survivable Flight Data Recorder (FDR).
