Engineering

Great article. Part of me wants to build a jet engine. Why?

- great situation where the cost of development is astronomically bloated (3~5B for new engines)
- You can bring it down orders of magnitude (100x reduction would be 3-5M, even less) with modern 2020s tech, perhaps (unchanged since 1980s) and aerospace co stuck in their ways, chasing contracts etc
- and possible if you do it the right way. 
- Yes it’s naive, but this is how amazing things start

Here’s how I’d do it:
- 3D printed CMC blades
- no multi stage axial, go simple single centrifugal compressor
- basic cooling
- no FADEC, just build simple like a ESCs/ECUs
- no certification - find some exotic use case (experimental, defense, space, no FAA)

Most of the bloat is in
- R&D
- requirements 
- certification

Cut all of it. Do it in a shorter period of time (10 years -> 2~3yrs)
