It's been a good couple days of lectures so far. Each point or concept is not necessarily complicated, but as always the devil is in the details. Where it gets tough is the interaction between all of the design elements and principles that govern the performance. Add in the fact that almost everything you can do seems to have a penalty or drawback as well as the benefit you're trying to add, and I really have a newfound appreciation for engine design. We are using a program called AVL Boost to model what effect a multitude of basic geometric changes can have on an engine's performance. I haven't started modifying anything yet, just analyzing the basic engine we were given as a starting point so far.
The fog was really freezing this morning, it was all over the cars and ground too. It also didn't really lift until about lunchtime. While eating dinner tonight I was watching a show about a drive up the coast of Scotland. Learned some interesting things - and I might have to try and find a "Smokie" while I'm over here. Did you know one citizen had an idea to train sea gulls to spot German U-boat periscopes by teaching them that there would be fish to eat behind them?!
Well it's nearly 8pm, and the bus home was a bit slow, so I'm going to have a go at sorting out some more of the engine design assignment. You're welcome for all the proper English :)
