Abstract

Fuse technology concerns projectile trajectory initial segment nutation law issues, semi-empirical expressions of nutation law were got in initial segment of projectile exterior ballistic by mathematical model, external ballistics theory obtained and MATLAB to fit the data. Processing and interpretation issues were solved for discrete test data paper target method obtained, and accurate nutation cycle can be obtained. The problem solved is traditional nutation test discrete data can't give real maximum nutation angle and the system is too small.

Key words： external ballistics; numerical fitting; nutation law; nutation angle; empirical formula
