I don't know how much of a problem it is in real life, but in movies you always see helicopter blades being destroyed by missles, etc. and causing the copters to descend out-of-control and crash.
My idea is to have glider wings that can pop out from the side of the helicopter body so in case of an
emergency, it can glide down to the ground and hopefully remain upright and float forward instead of doing the death-spiral we usually see.
I have no idea if this would actually prevent crashes, but I saw a small helicopter flying over my house today and a few minutes later, a small plane flew by, and I had a thought that this could work!

How helicopters can stay afloat (aglide?) if anything but their blades is damaged. [jutta, Sep 14 2009]

Barring catastrophic rotor damage, most helicopters can
land
safely (not easily, but they can) without power.
In the case of catastrophic rotor damage, first, likely the
airframe and hydraulics are badly damaged as well,
including the hydraulics that pop out your glide wings.
Second, the imbalance during the rotor destruction is
likely to pitch the helicopter on its side or similar weird
effects that won't make it real flyable.
Finally, normal helicopters do not have particularly good
glide characteristics and frequently don't have a lot of
forward speed in normal operation. A glide would only be
possible during high speed flight, and the design of glider
wings would be difficult for a helicopter body.
Generally not practical, maybe not possible. |

I would give my left testicle, (if I were a man), for a
bristolz drawing :-( of this. I think then it would get
at least one bun. So I'm gonna give it one just for the
hell of it. |
|
| |
Practicality being an option on the 'bakery, I'm going to advocate for the wings being installed in an airbag-like manner, so the hydraulics are irrelevant (+). |
|
| |
most helicopter 'crashes' are due to engine failure, and end rather benign in the helicopter autorotating to the ground. The few instances of disintegrating rotor (that are not due to something that would have killed the pilot anyways) would probably not be helped by glider's wings - as they are mostly due to the rotor hitting something because the 'copter is near the ground.
All-around airbag would be more helpful in those instances |

Anyone who essays air travel in a vehicle that is nothing more than a linear descendant of the common kitchen eggbeater deserves whatever they get. |

Yeah, yeah, aircraft humor... |

Thanks for the support blissmiss and normzone! |

I know it's not the most practical idea, but thinking of my little mini model helicopter, when the little piece that attaches to the flybar comes loose, the thing just plummets, and I can imagine little nylon wings at least slowing its descent, and possibly catching in the wind, gently gliding it down. |
|
| |
OK, so maybe I'm dreaming, but that's what this place is for, right? |
|
| |
And now I've experienced my first fishbone-rated idea... oh well. |
|
| |
Yeah, but you also have a two bun idea,
I dream of ideas
of
that sort of quality. Then I wake up and forget them all :( |
|
| |
its not over till the fat lady sings... |
|
| |
& the ideas that split the vote are usually the best, welcome to the madhouse. |
|
| |
I'll wager if you offered this pilot some airbag-style short wings, he would have said "it couldn't hurt" or something of the sort (link). |
|
| |
kaz, po, and normzone, thanks for the encouragement! |
|
| |
...and back into non-fishbone territory - woo hoo! |
|

The problem is the helicopters intermittent lack of forward velocity. If the blade snaps or the Jesus bolt (my ALL TIME favorite part name) goes while in a hover, the wings will be near useless. If they fail during a time of significant forward motion, they better pop out with control surfaces and have controls for those surfaces pop-up in the cockpit, so sorry (-).
On a similar note though I think you can get a rocket deployed parachute for a helicopter if you could figure out a way to mount it above the rotors (or blow the rotors off with the deploy, but that sounds dangerous to others.) Technically if you switched that parachute into a parawing, then this idea could work. |
|
| |
OR maybe fit a gi-normous airbag to the bottom. |
|
| |
The powered rotors are down and fixed, angled wings radiate out of the top. The copter's descent is theoretically slowed as it spins, just like those "helicopter" seeds. |
|
| |
Hm, interesting ideas, all. |
|
| |
And Jutta, autorotation is really cool if the rotor and blades are still in place during a malfunction. |
|
| |
dont some copters come with a pair of huge parachutes? |
|
| |
Hey maybe we can combine ideas. in case of emergency aim for all those inflatable home villages that were posted earlier, like big air bags for planes. |
