So let's just talk about the CFM56 and the V2500. How would you compare the architectural design of these two engines?

This is very similar because I have to say I create some things for my students. I teach young engineers about the function of the turbo engine and everything else. This is a similar engine because they go on the same airplane. You can see that both engines go on the Airbus 321, 320, 319 and the V2500 goes on the McDonnell Douglas. This is a little bit different. But what is the difference? The difference is the material used to build the engine. For example, you don't have a situation where you have two types of fan cases like in CFM or two types of material, such as the titanium configuration and Kevlar configuration. Also, you don't have the same material every time for the fan blade. The fan blade on the V2500 is made from titanium material. The fan blade on the CFM, on 5B and 7B, is made from composite material.
