Explicit form of the "modified point mass trajectory model" for the use in Fire Control Systems

Abstract

The main objective of this article is to obtain equations of motion of the spin-stabilized projectile in the presence of non-constant wind. Introducing models allowing utilization of inhomogeneous wind is dictated by new possibilities created by the use of e.g. lidars in the Fire Control Systems (FCS). Constant feed of wind data can replace meteorological messages, increasing the FCS effectiveness. Article contains results of projectile flight simulations which indicate the positive effect that the derived explicit form of the model has when considering software development for modern Fire Control Systems.
