| 中文摘要: |
| 在某型飞机的试飞过程中，发现大气数据传感器的输出信号在传输线上，有分布电容对其进行干扰而产生自激，影响了传感器的数据精度。经过分析和对比试验，提出了在成品设备直流输出高、低端各接一级消激电路，来消除分布电容引起的自激干扰，提高成品设备的抗干扰能力。通过机上试验，验证了该方法的有效性。 |
| 英文摘要: |
| It is found that the data precision of atmosphere data sensor is affected during the test-fly of a certain plane.The reason for this is that(sensor's) output signal on the transmission cable brings on a self-excitation caused by distributed capacitance.By contrast experiment,a solution is proposed that the self-excitation interference can be eliminated by connecting a eliminate circuit at both direct current high and low carry-out terminal of shelve-off equipment in this paper.The method can improve the anti-jamming ability of finished product.Finally,its validity is verified by experiments. |
