As an aeronautical physics enthusiast, military nerd and avid VTOL fan, it was fascinating observing the aerodynamics of the F-45. Your effort was well worth it!
I have no clue what any of this means beyond what’s explicitly spelled out but it looks cool, the musics good, and the editing is captivating. As such I have no choice but to watch your aerodynamics simulations until my brain is satisfied
Well I just ripped the 3D models out of VTOLVR with Asset Manager, put that in Blender, made it watertight, then exported that as an .stl to the CFD program
Out of curiosity. When you were ripping the model did you also have to assemble it from multiple pieces? I was trying to get an FA-26 model so that I could print it, but couldn't find it as a single file. Only a few dozen separate files of different parts, some of which were scaled differently
ikr, but I'd say the game modelled it correctly - there's not much you can do. The centre of lift just _can't_ get back behind the centre of mass with this kind of design. All you can hope for is maybe descending far enough (w.r.t. terrain) into thicker air so the VTOL mode has enough authority to pitch nose down, or the level out. So if you're high enough, maybe dropping all ordinance and fuel dump might help? Have ya found any other methods that work sometimes?
@@SLGY I normally go 45 degrees and try to push the nose down. Then I go burners if I have enough altitude. I guess I just need more practise to avoid getting there in the first place
Try to spin the aircraft on the horizontal axis before going straight. while the nose is pitched downwards, try to level off while applying afterburners on and off as necessary to build forward momentum. Alternatively try to destabilize the aircraft farther to fly downwards in attempt to get airspeed before levelling out. I speak from experience. The spinning has an added benefit of offering windows to launch fire and forget missiles to keep anything trying to attack you in your vulnerable state busy.
It was fairly normal aerodynamics in those flight regimes, the results didn't look interesting or have any particular quirks about it so I left it out of the video.
Nah Doppler radar can't get those kind of signatures from just air. The aircraft materials are what's creating the bounce back. Even Doppler weather radars need water droplets in the air to bounce/refract the Doppler signal.
@@spikenomoon Think about it this way. To detect something you want maximum detection, but minimal noise. If a radar could detect the turbulence of the air, then thermals and wind would just destroy your viewer. So they look for hard body returns. A stealth fighter fights this in two ways. They have radar absorbant coatings (Less signals leave to go back to the radar) and 'stealth construction' which is the shape of the overall aircraft (instead of bouncing the radar signal back towards the radar it disperses it back in a larger area like a shotgun. Both combined (though shape is more important) means that what should show up as a massive object in the sky, only returns enough signal to look more like a small bird. The idea for stealth is having the radar cross section (the shape that the radar sees) be smaller than the noise threshold (imagine the region where anything inside it COULD just be a thermal or a harsh wind. Technically its still always ON the radar screen, but its not a strong enough signal to make use of for detection or weapon guiding, until its usually too late. An example of this would be the F107, which looks ugly as hell, but might still have the best radar cross section of all time (I imagine only a few people on earth would know if thats the case) since that's what it was built to do. There is a book called "Skunk Works" by Ben R. Rich which talks about this in depth as he is basically the father of stealth.

That's so cool!
Thanks! Next will be your AV-42 in the sim to see how draggy it is, though I might save some time by just loading in a bus 😋

04:09 haha thats 1 way to hide from the enemy
lol it _just_ fits in there
Awesome work man!
Thanks!
what crazy cool editing!! more of these for other sims?
More to come!
Man, this is super awesome! Great video. How did you get VTOL VR gameplay into FluidX3D?

Yeah there was *lots* of mesh repairs, welding, joining, boolean modifiers. I think it took about 5 hours to make it a solid object
2:41 what's the best way to get out of this? I often find myself in a similar situation after a 45 vs 45 dogfight.

viffing usually solves it for me, might need to jettison if youre really thicc but idk
@@jaidensky5738 Yeah, viffing seems to help one get out of it

Nice! What about though cruising normal and high speed normal angle?

this need more views
Next up will be a FA-26 vid that's nearly done 👌
I have nothing. How?
I have way too much free time 😟
Why can’t Doppler identify the path of a stealth fighter
Well 'stealth' just means *delayed detection*, not _no detection_ - doppler will pick it up when it's close enough
But couldn’t Doppler pick up the turbulent air it’s displacing? Not the actual plane but the path it’s flown??
