Analytical Model for the Velocity and Position Measurement of a High-Speed Projectile

Abstract

This technical memorandum presents the results of analytical, numerical, and experimental studies predicting the velocity and position of a high-speed projectile. Velocity and position predictions were made using computer modeling and simulation to find a reliable and cost-effective velocity sensor. The two most popular magnetic field sensing devices, the copper wire sense coil and the Hall effect sensor, were examined. An axisymmetric, 2-D finite element analysis model was developed (1) to calculate the field distribution due to a permanent magnet embedded in a projectile and (2) to verify the analytical model. Experiments were conducted and confirmed the accuracy of both the analytical and finite element models.
