I hyper focused on 3D cad in school. I know details on how to manufacture stuff. My contacts list in my phone could probably get any part a human could possible design in the right place to get made...especially gun parts. I really like sheetmetal parts. I really like riveting. I spent 20...
building on previous:
If going remote with a rod isn't available
Curie temp magnets in the 900c range do exist like Hiperco 50 $$$
Coppers conductors resistance at that temp is going to be up there.
no insulators other than ceramic that are going to handle it.
Thermal expansion will be...
Anyone here from SpaceX...
They are doing something absolutely wild no one has had the balls to try. They are strapping rockets to industrial fluid tanks and trying to put them in orbit...
Adjusted for inflation:
1:US nuclear Arsenal 10 Trillion
2:WWII 5 trillion.
3: Iraq Afghanistan 5...
None of the profiles in DO-160 are going to be applicable to eVTOL environments.
It's neat when you're in the lab the Turboprop profiles sound like you're in a turboprop. Helicopter profiles sound like helicopters. eVTOL profiles sound like... they don't exist yet.
You could do the random...
1st off, not like anything I've seen/I don't recognize the formatting. BUT It sure feels familiar.
Looking at -A- I'm guessing a Datum simulator/gage tooling, is installed into the associated bolt circle to establish a central axis from which A1 dimensions are pulled. Basically saying hey this...
300 amp 28v DC starter generator. Last I checked that's 8.4kw... DC.
Off grid as it gets.
--------------------
I'm fairly impressed too. There are sensors in the battery to help monitor if they do decide to catch on fire. But I promise I watched it hit 15.2 volts at the peak inrush... then...
I promise we started with basic physics and worked up. Gas driven generator is the only way. A turbine would be arguably better, but development costs are way too high.
I'll second MIL-R-47196A. They have a fantastic table for tolerance that requires a minimum diameter, then a fairly strict height tolerance (about .010 tighter than where that table OP posted came from). Very easy to inspect and flow down to manufacturing without requiring anyone to realize D is...
Okay I wrote this as a forum post, but ignore that. Lets sus out the main question at the end. "Sorry to leave you hanging... took a minute to come back to this project.
So I just looked... the batteries are closer to $10k. But like I said We’re making an engine driven generator. I was joking...
Hey so I'm building a generator system with an existing 300 amp 28v DC starter generator. For most of it's use it's going to be driven by gas engine to make about 200 amps. But I need it for starting a large engine, that pulls north of 500 amps spike on inrush. The system currently uses a large...
