l Velocity vs. Compression Ratio GraphsFigure 1 – Without AfterburnerFigure 2 – With AfterburnerConclusion / DiscussionDuring the development of the software, we were able to see general relationships between the different variables the user imputes and the output velocity of the jet engine. We were able to see that the compression ratio has a large affect on the final velocity. As seen from Figure 1 & 2, the relation between the final velocity and compression ratio is not linear. Our program determined the most efficient compression ratio, while not using an afterburner, was 11.8 while the other variable data remained constant. We were also able to see a linear relationship between the diffuser/nozzle ratio and the final velocity. However, we did not find a ratio that would maximize the output velocity of the jet engine.We were able to see a non-linear relation between the heat input from the combustor and the final velocity. Due to a small sample size, we were unable to see the addition of more heat input reducing the final velocity. However, we know there must be a maximum value for heat input to maximize the velocity, or one would be able to continue adding any heat input one would want to have incredibly high output velocities. Finally, we were able to see a great increase to the final velocity due to the use of an afterburner. This can be seen from figure 1 & 2. ...
