| Abstract: | The measurement precision of the engine ’s lubricant oil pressure that in the FDR(Flight Data Recorder) is lower than needed.Aiming at this problem,the working mechanism of the measurement circuit is analyzed in the first.And then the resolution is given by adding a measurement circuit of the power supply voltage beside the FDR.The working circuit is designed and the testing results are analyzed.So on the precondition that keep the inside hardware structure of the FDR remains unchanged,the precision of the engine ’ s lubricant oil pressure can be greatly improved,which can provide important proof to the surveillance of the engine. |
