Comparison of Modified Point Mass Model and Euler Flight Model

Cilj rada je usporedba i analitički osvrt na rezultate simulacije modela leta projektila primjenom Eulerovog modela te modela modificirane materijalne točke u programskom paketu MATLAB, a za zadani topnički projektil. Osnovna ideja je prikaz sličnosti i razlika te prednosti i nedostataka oba modela kroz računalnu simulaciju leta projektila. Osim navedenog u radu se prethodno detaljnije opisuje svaki model i njihove računalne realizacije. Zadani klasični topnički projektil i njegove tehničke karakteristike te aerodinamički koeficijenti su predstavljeni kroz grafove i skice. U radu je naposljetku odrađena analiza simulacija putanja za različite početne uvjete kao što su elevacije, mase i početne brzine.The work is about the comparison and analitical review on the results of the simulation of the projectile model flight using Euler model and the modified point mass model in the MATLAB software, for a artillery projectile. The main idea is to show the similarity and the difference between both models through a simulation of classical artillery projectile flight. Beside the mentioned analysis both models are described in detail as well as their numerical implementation. The classical artillery projectil and its tehnical characteristics and the aerodynamic coefficients are shown through charts and a drawing. In the end the work will show an analysis of the projectile trajectory for different initial conditions like elevations, masses and start velocities
