Ceramic Engines
Ceramic Engines
Just thought I'd ask the question as there seems to be a few knowledgeable people frequenting this forum.
Why haven't ceramic engines taken off. A Google search brings up hundreds of articles from 10 years ago saying ceramic engines at one third the weight of iron or aluminium blocks are just around the corner. Hundreds of YouTube videos show running engines. Turbos have long been made from ceramics, as has turbine engine compressor blades. Ceramic coatings are seen on pistons etc.
So what's been the problem with ceramic blocks? Light weight but brittle?

I think it all went to pot.
That's silly, ceramics will be used in the turbine section not in the fans. The idea is to allow a major increase in temperature, currently limited be existing materials, to allow better SFC. It will come eventually but right now nothing allows for a better life and reliability than the current materials.

They are to britle and that makes them not flexible. In the cold section subject to fod they break and in the hot section they fatigue due to the constant change in temperature. Off and on and centrifugal loads applied. They may come but at present single cystaline blades are becoming more avaiable

Advances in metal technologies such as titanium composites and new metal alloys, offer better temperature, strength and durability compared to the advantages ceramics potentially offered a decade ago.

Lockheed says nuclear fusion on the way
The "true atomic age" of limitless electricity without any radioactive waste or carbon dioxide emissions could be a reality within a decade, according to a US aerospace company that has claimed a breakthrough in nuclear fusion.

Check this out. Need to watch the whole thing some new stuff I've never heard off.

I thought the metal matrix that some compressor sections were made of was a type of ceramic.
Interesting video on Thorium, I'd never heared of it. It seems to be an energy source of the future, after uranium runs out. As for solar and wind, I like both in sensible applications.
