A thing of beauty, the Kestrel remains my favorite. She is the brick shithouse without rival.
haha exactly 👌
This thing uses the same logic as the F4 phantom. You can make anything fly as long as you give it enough thrust.
Haha exactly 👍
You are not taking into account the sheer will power of the pilot. Every time it'll get the job done, the pilot just needs to believe it (cuss) enough and oh baby she'll fly alright.
It'll sure need to be something supernatural like that, because nothing in the real world would be enough to make it fly lol
Truly amazing video and analysis, not sure why this doesn't have more views. Great job.
It'd never work, but its a great aircraft to fly 😁
What about Dornier Do 31
That thing had 8 jet engines just for VTOL
And well it did work
Let’s go it’s finally out. Also I think the inner “engines” are for apu and RCS
ikr I had a scratch around the wiki and Discord, I don't think even Baha really knew what they were meant to be originally 🤷♂ Put it this way, to maintain even level flight in conventional mode they'd _have_ to be engines
You have to remember the AV-42C is likely pressurized, it can carry troops. I would definitely be able to imagine that being the PACKS of the aircraft. If not, it would be quite funny to imagine the 42C having powerful computers onboard needing cooling while also lacking a RADAR.
True, would be a good spot for the packs, maybe some oil coolers, etc. Makes for a good services compartment. But damn if this was pressurised too, that's even _more_ weight
@@ierdna1004 I don’t think the kestrel would be pressurized. I rarely find my self above 10,000 ft in it.
@@shermanfox7338 clearly you've never done a high-altitude bunker buster drop from around Angels 40, guiding in that Paveway out of sheer force of will.
You're going to like the just released FluidX3D v2.1 update. GPU voxelization now takes milliseconds, not minutes! :)
I just tried it out, that's an incredible difference. Even when running a stop-motion STL sequence and an LBM that uses *all* the GPU memory I don't notice any slowdown when its revoxeling now. That's a game changer for me, thanks!
@@SLGY you're going to like v2.2 even more :) Moving/rotating things are now super simple in the setup script! See the "radial fan" and "electric ducted fan" setups!
Absolutely beautiful!!
love the analysis
can someone explain how this video only has 20 likes?? this deserves way more. great job
Thanks!
Excellent!!
Amazing simulation 👍👍
the Kestrel is, actually, somehow controllable without her tail if you have the balls of steel to try and fly it with RCS set to ON, rather than AUTO... So long as you don't lose your engines as well...
Yeah that RCS can be pretty important when bits start falling off that airframe
RCS always on
One day, we will have enough power to run CFD in real time
Since VTOL VR had a new aircraft added a few days ago does that mean we're going to see any video on that?
Yeah I'll fire up the wind tunnel and do some tests on it soon 👍
I think you should make a tutorial on how to use fluidx3d
"I own and operate several nasa super computers"
Some might say it's a waste of super computing power but what else would I use them for!?
@@SLGY oh, idk, bruteforcing a genetic cure for cancer against the human genome in a fully emulated human body with 100% accurate atomic level interactions over 10-15 thousand instances at a time... lol
That's awesome! Do you have any advice on learning fluidx3d though? When I was trying to learn it I had a difficult time figuring out how to use it with my own models and settings, let alone animated 3d objects...
I'm hearing ya, it's a real pain in the butt to do tricky things with. I'm hoping to do a tutorial video on how to use it someday...
Could you get data from different points in space? to measure many forces?
Not sure with that, I'm sure you can 🤷♂️. I've only used the function which calculates the total force exerted on the object for each frame
@@SLGY Where in the code can I change the colors like @ 4:35? Thanks!
How to change the fluids colors, I like the palette
Oh well they change depending on the vorticity of the fluid at that point, so you just change the speed or limit the range of what's displayed in the 'defines' section of the code
@@SLGY Thank you!
