Day 1- Wednesday, May 8

Today was a little different than what I will be normally doing because the upper management for the Aerospace Division came today for a tour of the labs. This meant that most people were busy preparing for the visit. Because of this Mr. Melzak was a little busy. I was able to shadow a coop student, Jacob Greco, from Case Western University working there. He works on solving different design flaws in prototypes in the fuel injector nozzles. The fuel injectors are the parts in a combustion engine that inject the fuel into the combustion chamber to be ignited to provide power. The combustion chamber is surrounded by ten to twenty of these fuel injectors that spray the fuel into the chamber in a way that burns the fuel evenly through out to create a constant temperature inside the chamber. The nozzle is what regulates the flow of fuel into the combustion chamber and distributes the fuel in an uniform mist. The coop student job was to fix problems caused in the assembly of the nozzle. On example of this was that two pieces of the fuel injector nozzle are bonded together by a metal ring that is melted between the two pieces, but the ring that was used had to much material wich made a gap where the two pieces should be bonded. He had to calculate how small the ring could be, but still have enough material to cover the whole bondering area of the two pieces without leaving any gaps.
