Accurate computation of the trajectory of the spin and fin-stabilized projectiles

International journal of mathematics and computers in simulation. Issue 2, Volume 3, 2009. – 73-80 р.The modified projectile linear theory trajectory report here will prove useful to estimate trajectories of high spin and finstabilized projectiles. The model of the modified linear theory is compared with a 6-DOF trajectory model. The computational flight analysis takes into consideration all the aerodynamics variations by means of the variable aerodynamic coefficients. Static stability, also called gyroscopic stability, is examined. The developed computational method gives satisfactory agreement with published experimental data and computational codes for atmospheric projectile trajectory analysis with various initial firing flight conditions.
