GE Aviation and the Ceramic Matrix Composite Revolution

[@kingcosworth2643]

A 6o:1 comp ratio with an axial compressor is simply incredible. I have a textbook on turbines written in the sixties and 6:1 was where axial turbines were at that time...

[@neillenhart6838]

Yeah I know I’m looking at the FAA AC 43.13 and 8083 and just mind blowing how fast the impossible became possible in the decades since the low end compression ratios.

[@tetrabromobisphenol]

With a 60:1 pressure ratio, half of the compressor is now technically a "hot section" too! They probably don't need ignitor plugs anymore, the air will be WAY above the autoignition temp of even JP-8!

[@MrPoornakumar]

KingCosworth Who knows? The next stage might be "double jacketed" version of by-pass arrangement. The outer-most jacket will have unheated air passage, while the inner jacket around the main engine will be heated version, conserving heat & enhancing heat efficiency.

[@kumark214]

Of course it’s with multiple stages. Increasing comp ratio is fine even back then by having more stages but doing it at light weight is where these make a difference.

[@realmetallurgist8493]

I worked on these composites back in the '80's, but the company I worked for never cracked the code to make them work. It's nice to see that someone else did.

[@andyharman3022]

I worked on ceramic components for gas turbine engines in the early 1980's at Allison. Back then, they were monolithic parts we were working with, and very brittle. It's nice to see how far the technology has come in the last 30-40 years.

[@bluwhaleceramic902]

Silicon carbide (SiC) is a structural ceramic material with excellent performance - super hard, wear resistance, low thermal expansion coefficient, excellent thermal stability and so on. Very suitable for aerospace applications.

[@kumark214]

But brittle. Less so with cmc.

Man once they get some CMC Performance Improvement Packages into the GEnx, getting a 787 NG is going to be a walk in the park. It's impressive that GE is using raw materials science to keep pace with the kind of advancements like geared front fans. It's starting to feel like we're within 30 years of apexing in the jet engine industry.

[@mikefigures5541]

I once found video of the last j58 static engine test. Think it was conducted at Edwards. The exhaust components were glowing so hot they were practically transparent. Hard to believe the whole thing didn't end up a molten glob of slag on the concrete. When the engine was shut down, it quickly cooled off to a dull gray. Pratt & Whitney. Now they can build an engine. The j58 rules! Think the video was classified because I went back a few days later and it was gone.

[@georgemuller6038]

The J-58 engine was used on the A-12 and the SR-71 Blackbird and could fly at the speed of Mach 3.2. The afterburners had a lining of Ceramic to prevent them from burning up. It was designed in the 1950s and 60s.

[@robertirish4485]

CMC is really revolutionary. GTRE must work on it & develop.

[@isuzu343]

GTRE neither has the technical acumen nor the financial backing. Bleeding edge technologies do not appear out of thin air. GE has built dozens of gas turbines over decades to get to where it is today. The only way CMCs will ever be made in India is if the manufacturing technologies are give to it as part of a major military deal with geopolitical considerations.

[@kumark214]

GE has been researching this for past 30 years. India is still unable to produce single crystal turbine blades with nickel alloys, a 30 year old tech. I have seen the Kaveri Engine at drdo which was being developed for past 30 years unsuccessfully. If engine produces enough power it is overweight, when weight is reduced it vibrates too much. It is primarily because of partly skills and mostly government cluelessness of investment in long term r&d. loss due to failures during research is questioned by CAG in India who are accountants with zero knowledge of engineering. Until and unless government policy changes and fund private firms to do long term research and classify failures during development as investment and not loss, India will be behind the curve.

[@carmelpule6954]

Looking at 8:32 , now I know the reason why I could not get first time the correct angle of the stator blades in the compressor stage. Fluid flow determination is so difficult and experimentation is the best way to go. When one sees the facilities required to make such high technical products, all I can say is gone are the days when the average family man can experiment in his garage to make issues are microelectronics and jet engines...... which I do consider them on the same level of complexity. We live in a world of a few technical intelligent people and all the rest follow..........more like philosophers really and social work! and Oh I forgotten the entertainment fraternity....... they all live in such a simple but so popular world. Sometimes one wonders what to advise young people which way to go! Congratulations to all the researchers and other members of the team who shoulder all these headaches to bring better products for a better life.

Wondering about doing the blocks of piston engines out of this. Also the heads of the pistons and maybe some coating for the valves. Exhaust manifolds, turbo charger components(both housing and rotor). Carbon fibre for the structure and external panels and this stuff for the hot components in auto industry. How about brake rotors, would it be good and durable? Would it withstand the stress?

[@Flightstar]

+Aleksandar Popov Time will tell. Obviously this technology is at it's infancy, or at least in it's toddler state, Development costs are so high at this stage that only the military and large scale commercial operations can afford it. It looks very exciting. If it and can withstand the test of time and endurance, it should eventually make it down to a cost effective alternative in domestic technologies.

[@mykytakostiuk4196]

Aleksandar Popov Koenigsegg uses ceramic coating on pistons upper surface

[@mytech6779]

For specialty engines maybe, but the way current government emissions bureaucrats have written the regulations there is no need to go beyond cheap iron or coated aluminum. High combustion temperatures increase the ratio of nitrogen oxides in the exhaust, though said high temps also greatly improve fuel burn efficiency reducing total exhaust (assuming the extra efficiency is used to reduce fuel consumption at a static power, rather than increase power at static fuel use.) nitrogen oxides primarily combine with unburned fuel in sunlight to make rather nasty smog and when not combined with VOCs NOx can contribute to ozone depletion. Fortunately they are not long lived molecules, eventually degrading to either nitrate fertilizer or N2, where as CO2 must be stored either as dry biomass or carbonate minerals to reduce total atmospheric levels.
