Jurnal Mekanikal, June 2009screen is illustrated in Figure 4 that shows the graph of normal-force and dragcoefficients versus angle of attack for body alone configuration at Mach Number 2.Figure 4: Result screen3.4 Rocket data ScreenRocket data screen will be shown when the ‘view’ menu of the result screen inselected. This screen (Figure 5) contains all the geometric information of the rocketmodel used in the program calculation. This is particularly useful for user to keeprecord and or to verify the geometrics of the rocket designed.Some other additional functions are contained in the program such as ‘Print’and ‘Save’ function. These two functions only occur in the result screen and rocketdata screen.34
