Turbine Blade Coatings

A discussion about turbine blade thermal barrier coatings and their sensitivity to contamination. As a bonus, we start the video off with a contest you could win... Contest was won in less than 12 hours! The interesting thing about all 3 scenes was there were matching or near matching parts, but they were for different engines. 1: Front stages of an LM2500 compressor rotor, and parts of the variable stator vane system from an LM1500 next to it. 2: Front stages of another LM2500 compressor rotor, with one first stage blade from an LM1500 next to it. I tried, and it would not fit. 3: The unbladed compressor rotor of another LM2500 sitting next to the compressor cases of an LM1500. Here's the kink to the video about ceramic J47 turbine blades: https://youtu.be/1Vzbd3kO7kU?si=8l_THWlyeK3jlpy9 Here is the link to my playlist about the AI25 engine in the FP-5 missiles: https://youtube.com/playlist?list=PLE5I9ZZNPu1PjuwJl0HnkLknEbcl-2PGs&si=6FoHT7gsy2trR9UG
