A community for your defence shitposting needs
Rules
1. Be nice
Do not make personal attacks against each other, call for violence against anyone, or intentionally antagonize people in the comment sections.
2. Explain incorrect defense articles and takes
If you want to post a non-credible take, it must be from a "credible" source (news article, politician, or military leader) and must have a comment laying out exactly why it's non-credible. Low-hanging fruit such as random Twitter and YouTube comments belong in the Matrix chat.
3. Content must be relevant
Posts must be about military hardware or international security/defense. This is not the page to fawn over Youtube personalities, simp over political leaders, or discuss other areas of international policy.
4. No racism / hatespeech
No slurs. No advocating for the killing of people or insulting them based on physical, religious, or ideological traits.
5. No politics
We don't care if you're Republican, Democrat, Socialist, Stalinist, Baathist, or some other hot mess. Leave it at the door. This applies to comments as well.
6. No seriousposting
We don't want your uncut war footage, fundraisers, credible news articles, or other such things. The world is already serious enough as it is.
7. No classified material
Classified ‘western’ information is off limits regardless of how "open source" and "easy to find" it is.
8. Source artwork
If you use somebody's art in your post or as your post, the OP must provide a direct link to the art's source in the comment section, or a good reason why this was not possible (such as the artist deleting their account). The source should be a place that the artist themselves uploaded the art. A booru is not a source. A watermark is not a source.
9. No low-effort posts
No egregiously low effort posts. E.g. screenshots, recent reposts, simple reaction & template memes, and images with the punchline in the title. Put these in weekly Matrix chat instead.
10. Don't get us banned
No brigading or harassing other communities. Do not post memes with a "haha people that I hate died… haha" punchline or violating the sh.itjust.works rules (below). This includes content illegal in Canada.
11. No misinformation
NCD exists to make fun of misinformation, not to spread it. Make outlandish claims, but if your take doesn’t show signs of satire or exaggeration it will be removed. Misleading content may result in a ban. Regardless of source, don’t post obvious propaganda or fake news. Double-check facts and don't be an idiot.

I think i heard one time that helicopters can jettison the rotor so you dont get chopped up
Unfortunately, that won't stop the blades from spinning, meaning the danger isn't averted.
You shear the blades so they shoot outwards. I couldn't find an irl testing video, but here's a render.

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.
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.
Autorotation is mostly copium as well.
Explanation
Wow. I'd be nuts to fly one of those things. 6000 VVI sounds like suicide
Yeah, helicopters are the apex predators of soldiers and rich people. Even if you pull off the perfect autorotation, the glide ratio is still only a maximum of like 3:1.
I think I remember reading a report somewhere that more people have been killed by practicing autorotation than have actually pulled it off in the wild.
Now you have blades shooting away from the helicopter at a high speed which could kill someone.
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.
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.
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.
not much, considering how many of Ka-52s were shot down without pilots ejecting
Pretty sure someone was lying to ya
Several models of helicopters have ejectable blades, this article mentions a few, and has a diagram of the blade severing system.
Damn never would have expected that. Thanks for showing me something new!
