Design of the FAE Solid Fuel Cloud Concentration Fast Measurement System

The solid fuel cloud concentration measurement technology is the key factor for the FAE to realize the best fuse-warhead coordination and enhance the damage power, but the existing multiphase concentration testing methods cannot meet the demand of in-situ measurements. The general model of ultrasonic attenuation in solid-gas mixture is investigated and simplified by numerical analyses,and the fast calculating algorithm of mixture concentration of air and metal particles is established. Assembly method with dual core is adopted to design the concentration measurement system, in which the signal sampling function and concentration calculating function can be achieved independently. An experiment is conducted with a high-precision concentration measurement device to testify the characters of the concentration measurement system. The results show that the concentration measurement system performs very well in both accuracy and speed,so it can be used to test the concentration of FAE fuel cloud.
