Comparison of explicit and implicit forms of the modified point mass trajectory model

Baranowski L., Gadomski B., Szymonik J., Majewski P.

Journal of Theoretical and Applied Mechanics

2016

Vol. 54 nr 4

1183--1195

The article compares the results of trajectory computation for a 35 mm projectile using two forms (explicit and implicit) of the modified point-mass trajectory model. All necessary ammunition parameters (aerodynamic coefficients, dimensions, mass etc.) and initial conditions for differential equations are provided. The results of numerical integration (using non-stiff fourth-order Runge-Kutta solver) are presented in form of projectile trajectories projections onto vertical and horizontal planes. Data tables comparing both models in terms of projectile position and velocity in chosen time steps are also attached.
