摘要
介绍了应用放射性同位素γ射线测量飞机燃油密度的机理 ,并利用自行设计的实验室飞机燃油密度测量系统验证了测量机理的可行性。测量结果表明 ,该方法能够达到较高的密度测量精度 ,具有广阔的应用前景。
The real time measurement of the aircraft fuel density is crucial in the aircraft Fuel Quantity Indication System (FQIS). This paper introduced the principle of using the radioactive isotope gamma rays to measure the aircraft fuel density. The results of density measuring experiments using in LAB measuring system have proved that this method is not only feasible, but also precise enough to be applied widely to real time aircraft fuel density measurement.
