Sierra Turbines offers:
Replicable mass, at the speed of Defense requirements.
Introducing Aurelius
100% US Supply Chain - Manufacturing, materials, and even the additive equipment is made in the US.
We’re not running to Germany or China for additive equipment parts or raw materials.
Made in Oklahoma [soon], in an ITAR compliant facility. It doesn’t get any more American Made than that.
Reliability
Delivering commercial jet-engine platform features and reliability for microturbines.
Lengthening the mean time between overhaul [MTBO] for microturbines was a requirement at inception. Moving the needle meant exponential improvement vs. incremental.
By removing point of failure parts such as seals, tubing, and connectors, key drivers for overhauls have been eliminated.
Our models show a 40X improvement. We are now in the process of testing to gather the proof. Stay tuned for details.
Material choices also contribute to reliable operation for both 1x use, and dependable/constant operation.
Sierra Turbines is creating thrust and generator turbines that exceed current understandings of what is possible, and remove limitations of where they can operate.
Building on space-qualified materials opens new possibilities and creates interesting connections. Like this one. Coincidence? We don’t think so.
