Hey guys. As the title reads, I am a part of a research project and we will soon be testing a 100lbf jet engine. We take safety very seriously and want to take all the proper precautions in order to ensure everybody involved will come out of the experimentafely in case something goes wrong. With that said, I am aware that the safest thing you can do is to stand as far away as possible. A blast shield is not to be relied upon as the sole source of protection in case a jet engine explodes. At high a RPM, the amount of kinetic energy in those blades is fatal. So I am asking for advice on building blast shields. From my limited research thus far, I see that some are made of Lexan: http://en.wikipedia.org/wiki/Lexan Thank you everybody!
