zaphod 16 points 2 years ago
I think the main problem with down-firing ejector seats was that they require a minimum altitude to work.
SuckMyWang 5 points 2 years ago
What about sideways?
SynopsisTantilize 5 points 2 years ago
I'm gonna turn to YouTube to see what I can find. This is pretty cool. Cars should have ejector seats too.
rockSlayer 34 points 2 years ago
How many of those are intentional?
nullpotential 50 points 2 years ago
Attach the ejector seat TO the helicopter blades so that they both eject and you get a cool propeller and can fly around and it can shoot lasers and stuff too.

Too hard to accelerate the helicopter's larger mass to Mach 19. You might still damage the helicopter on the rotor blades.
TheMightyCanuck 40 points 2 years ago
So basing off another comment. Have the Ejection seat tied to the rotor and shaft (not in a way that the chair spins. Duh)
Then (as long as rotor hasn't disintegrated) you can eject the seat with the rotor, thus minimizing filet chances... Whilst also floating to the ground softly like those whirly paper helicopter things you played with as a kid
Boom. Parachute free ejection seat
Voroxpete 27 points 2 years ago
Nah, just do it like they did in WW1; synchronize the ejection to the rotor blades so you fly through the gap, clean as a whistle.
(Please don't ask about our experiments with the earlier WW1 method of "Fuck it, just shoot the propeller sometimes, it'll be fine". Turns out that doesn't work so great when you replace bullets with people.)
_haha_oh_wow_ 3 points 2 years ago
Didn't they also put some sort of armoring on the propellers back then?
Voroxpete 4 points 2 years ago
Some planes did, but early on they mostly just freeballed it. Turns out propellers are really big and heavy, and they can take a few bullets without breaking. Armour actually makes it more likely that fragments of bullets will fly back at the pilot.
_haha_oh_wow_ 3 points 2 years ago
Yeah, spall was my first thought when I read they just shot the propellers.

Toneswirly 19 points 2 years ago
I think i heard one time that helicopters can jettison the rotor so you dont get chopped up
Leate_Wonceslace 14 points 2 years ago
Unfortunately, that won't stop the blades from spinning, meaning the danger isn't averted.
JohnDClay 11 points 2 years ago
You shear the blades so they shoot outwards. I couldn't find an irl testing video, but here's a render.
TranscendentalEmpire 9 points 2 years ago
Mainly just copium for the pilots. Helicopters aren't like airplanes where you have glide time and altitude to decide what to do after something bad happens. If you watch fixed winged ejections there's usually about 30 seconds to a min after something goes wrong before the pilot decides to bail. Helicopters go from everything being fine, to a debris field in seconds.
Estiar 11 points 2 years ago
It's more about altitude than the ability to glide. Helicopters can do what's called Auto rotation, which means they actually can glide. If the blade seize up however, they can't autorotate. Helicopters fly a lot lower than most airplanes though, so they can't glide as far.
chiliedogg 11 points 2 years ago
The Kamov does it.
The individual rotor blades are separated from the center with an explosive charge and their centrifugal motion carries them laterally away from the vehicle as the seat rockets straight up.
skulblaka 4 points 2 years ago
As a bonus, whoever was close enough to shoot you down is about to get at least one heavy steel javelin flung terrifyingly close to their direction at high speeds.
I'm assuming here that impact with a long range SAM is probably something you're not about to eject from.
chiliedogg 2 points 2 years ago
In cases like that I'd imagine you'd try and eject prior to being hit, though I don't know enough to know how much warning time there is.

Why not blow the blades off first with a charge in the Jesus pin? Or have the seats eject siddeways or downward? Or like, open the door and jump out hoping you don't hit he rotors?
some_designer_dude 4 points 2 years ago
Canât believe I had to scroll this far to find the real solution. Eject rotors, then eject pilots. I think fighter jets basically do the same: eject canopy, then seat.
SpermGoobler 8 points 2 years ago
It's the KA-50/52
Annoyed_Crabby 13 points 2 years ago
Why not extend the seat sideway and eject that way?
sushibowl 13 points 2 years ago
I don't know of any ejection seats that go sideways, but early F-104 models had a downward track ejection seat. The main issue is that parachutes need some time to open and helicopters tend to fly pretty low. So in most situations you wouldn't be in a safe altitude to actually eject.
Modern zero-zero seats can safely eject at any altitude, but they do so by using a rocket motor to fly upwards to a safe altitude for the parachute to open. So because of the rotors, helicopters generally don't have ejection seats. The exception is the Kamov KA-50 series. It has explosive bolts blowing off the rotors before ejection.

lud 3 points 2 years ago
You are not thinking of crashes. The rotor won't have any time to slow down if the helicopter is about to crash into a building or the ground for reason unrelated to engine (or similar components) failure
Buddahriffic 5 points 2 years ago
Instead of ejecting the pilot away from the helicopter, why not design the helicopter to eject away from the pilot?
absentbird 3 points 2 years ago
But it just might be a lunatic that seat is for.
PalmTreeIsBestTree 7 points 2 years ago
Why not just eject sideways?
Contravariant 11 points 2 years ago
Heck if accelerating to Mach 19 in about 2 meters is acceptable you could just disable the rotors and only experience an acceleration of less than Mach 1 in just a few meters.
dashydash 4 points 2 years ago
The energy will have to go somewhere, so the passengers can stand up with their arms stretched, and when the rotating energy reaches them they can jump out and they will start spinning and their arms will act as rotors keeping them in the air long enough to reach land safely. You just need to make sure there aren't a lot of people on board because the energy will have to be divided on all of the passengers, if there isn't enough for everyone, they will fall to their death.
Mongostein 1 point 2 years ago
The energy can go in to ejecting the seat!
If it requires the energy of the rotors being stopped suddenly to eject, thereâs no chance of getting filleted
CanadaPlus 6 points 2 years ago
Or blow up the rotor at the hub first.
ByteOnBikes 3 points 2 years ago
It fails "the cool" factor so we rejected it.
Madison420 -4 points 2 years ago
When helicopters lose power they just fall. If the rotor head isn't decapitated then when you get ejected sideways there's s no zero chance you'll be julienned on the way down.
It's why the most (only version currently in operation) common method of helicopter ejection severs the head or blades while it's still rotating so it/they spin off and hopefully away and then the seat rockets away.
Madison420 -2 points 2 years ago
It's a fact. Helicopters in general do not have the ability to glide to a landing, they can auto rotate if the rotor is still moving and has enough momentum. If the rotor stops or detaches helicopters fall..
psud 2 points 2 years ago
"if the rotor stops" luckily in this universe we have conservation of motion so the rotor doesn't typically stop in flight
Sure though, were it to detach the helicopter would fly like a brick
Madison420 1 point 2 years ago
Autorotation relies on one main thing, air being forced past a freewheeling rotor..... Air that is being forced past because you're falling.
https://youtu.be/NLjFQJiJsZc?feature=shared
Notice the immediate loss of attitude? It's because they're falling, unlike planes which can generally glide after an engine failure.
Specifically we're speaking about helicopter ejection which in most cases means total loss of power or control or both. The only known helicopter eje tion seat(to me at least) to operate currently in modern combat is the ka 50/52.
One like this one which happens to eject and notably falls like a stone.

Just detach the blades. You can always re-attach them when you've landed.
