Abstract
U radu je izvršena analiza Eulerovog modela i modificiranog modela materijalne točke iz perspektive vanjske balistike. Prikazani su koordinatni sustavi koji se koriste: geocentrični, brzinski, nošeni, lokalni te aerobalistički koordinatni sustav. Zatim su izvedene jednadžbe Eulerovog modela kao jednostavnijeg modela leta projektila kod kojeg se uzimaju u obzir sila teža i otpor zraka. Kod modificiranog modela materijalne točke, uz silu težu i otpor zraka u proračun se uvrštava sila uzgona, Coriolisovo ubrzanje te rotacija projektila oko uzdužne osi. Nakon razrade jednadžbi, opisan je postupak računalne simulacije oba modela u programskom paketu MATLAB, te su dani tehnički podaci za odabrani projektil. Prikazani su aerodinamički koeficijenti koji su u uporabi pri analizi leta projektila. Na kraju je izvršena simulacija putanji za Eulerov model i modificirani model materijalne točke.
Abstract (english)
The paper analyzes the Euler model and the modified point mass model from the perspective of external ballistics. The coordinate systems used are as presented: geocentric, speed, vehicle-carried, local and aeroballistic coordinate system. Then the equations of Euler's model as a simpler model of projectile flight are derived, which take into account gravity and air resistance. In the modified model of the material point, in addition to the force of gravity and air resistance, the buoyancy force, Coriolis acceleration and rotation of the projectile around the longitudinal axis are included in the calculation. After elaboration of the equations, the procedure of computer simulation of both models in the MATLAB software package is described, and technical data for the selected projectile are given. The aerodynamic coefficients used in the analysis of projectile flight are presented. Finally, a trajectory simulation was performed for the Euler model and the modified point mass model.
