Why head restraints aren't used in military planes?
do they hate safety?
>>29465210
how does a pilot look around if he can't turn his fucking head
>>29465216
Not OP but you can look ahead, it just prevents your head from snapping forwards in a crash.
Though I can't see many instances where you're going to take a front or side collision in a fighter aircraft where you haven't already ejected or are dead from the force of impact anyway...
>>29465216
>>29465268
more important might be that it protects your neck from the weight of the helmet at high g's, also, do you really need to look anywhere else than forwards in a modern jet?
>>29465298
absolutely. In a close engagement which most modern air forces still train to preform, you need good visibility to track your opponent and maintain visual awareness.
Also consider that on almost all fighters the Radar is only capable of looking in a forward arc. To check on things immediately near your sides and rear you need to turn your head around.
Perhaps there is room for the military to consider such a device. I imagine comfort is a big concern. I don't know how comfortable those devices are. Perhaps the rule of cool simply means pilots and former pilot commanders haven't felt the need for such a dorky looking device. Honestly, that could be true. Perhaps it isn't necessary, I don't know.

Could have a 2 seater with the 2nd guy facing backwards

You're stupid
it's safer to not get hit, and to do that we (and yes, we is the correct word here) need to be able to look to the sides, up, down, etc. the current helmets are restricting enough as it is. under G's to reduce neck/back strain i've laid my head against the canopy more than a few times. the axis of force in a fighter is toward your feet/butt, and a HANS device doesn't do much because they're designed to restrain you from forward or "eyeballs out" G's.
If humans are still in fighters 20 or 30 years from now, one possibility could be powered exoskeletal supports for pilot heads; like a tentacle that connects the ejection seat to the pilot's helmet, uses a form of actuation to make the helmet virtually weightless and help the pilot turn their head while pulling Gs.
>>29465210
When would a fighter crash be survivable only because of this?
>>29466178
Just plaster plane with cameras and you don't need to look around anymore. Also with profiliation of laser weapons having glass cockpit and looking with you own eyes would be very bad idea. Many aircraft got DIRCM already, repurposing them to attack pilots eyes is just a software upgrade.

>>29466993
Isn't there a tank that does that?
>>29465298
You've never seen a pilot fly a jet
HANS devices only exist because some dumb hick died

If you're crashing and you're still in the plane a lanyard is not going to held you.
If you eject the g's are to launch you vertically aligned with your spine and air resistance will keep your head back
These only stop whiplash esque snaps from shock deceleration in car crashes, a driver needs focus on front and a wide enough FoV to get access to his mirrors, the main G's a pilot suffers are:
acceleration: headrest support
Pitch ups: increased g loading, pilots are reclined so there is no neck loading
Pitch downs helmet pulls up, not forward so unless this is a head clamp it can't help, but the real issue on negative g is we have no way of applying a suit to the head so blood pressure raises, again a lanyard won't affect your blood flow.
Looking all around is a key thing in all combat, why would we have helmet queued HUDs if the pilot only needs to look forward.
In WW 2 if over 75% of aircraft lost didn't see their attacker, situational awareness is the key in ground combat, ACM is 3 dimensional think of how much more demanding it would be.
>>29467159
The F-35 does it, buddy.
>>29465298
neck exploding isn't the issue with high G its the blacking out that kills you

Why not just a brace instead of restraints? Seems to have more freedom. Don't know if the protection it offers actually matters to pilot or not though.

>Don't know if the protection it offers actually matters to pilot or not though.
It doesn't. The only time a pilot experiences an extreme sudden change in forces of motion is during ejection, which is the most extreme, worst-case scenario to begin with. Even then it's only the tiniest manlets who are at risk of death from it, and everyone else gets such severe spinal compression that they're permanently shorter by an inch.
>>29465210
>Seat ejects
>Head ripped off
>>29467639
not quite. anybody's at risk due to flail and poor body position, and there's upper and lower limits to ejection seat weights. we are drilled to get ourselves in the proper position before we pull the handles.

Then why have a helmet at all?
>>29468679
because the oxygen mask and headset will slide around without a helmet. looking around with just the Davey Clarks on in the sim is annoying when they slide. and because bumping your head into the canopy hurts.
Martin-Baker seats feature a face curtain which the pilot pulls over his head to eject; it achieves kinda the same thing while also keeping arms tucked near the body.
>>29468445
kek
>>29468679
HUD, oxygen mask, radio, and a faces shield in case you have to eject.
>>29465268
This fucking jet just nose dived into the ground. We can't find the pilot's body, but at least his head is right here where we strapped it in

>implying they weren't widely used in formula 1 at the time
