User ID: 1426914  United States10/30/2012 03:42 AM  Report Abusive Post Report Copyright Violation | After watching "Air crash investigators" I thought of a simple solution to air crashes... Quoting: psilocybinaut111333 Only thing is, it seems too simple... I cant believe no one has thought about or implemented it already, so people of GLP please tell me why they dont simply fit all planes with a big PARACHUTE!!! If the extra weight is the issue, then surely someone could design one from carrier bag material! Surely the cost of one single investigation into a crash would be more than enough to kit out every single plane in the sky with its very own giant polythene parachute... Hell you could even use recycled supermarket bags! Save lives and the environment all in one fell swoop!!! I'm on Fire! 3:D So come on GLP, why the heebie jeebies dont they do this? Take that idea further and you might become rich if it starts to be implemented. Half the cash goes my way because I recommended it. :p |
| Anonymous Coward User ID: 26566897  Canada10/30/2012 03:46 AM Report Abusive Post Report Copyright Violation | Almost all air accidents happen on takeoff or landing at altitudes under 500 feet. Throw the chute at 500 feet and it wouldn't even unravel before the plane hit the ground. It would only maybe, maybe help for that freak 1 in 100 crash that takes place from 10,000 feet. They're not going to bankrupt the air industry for an accident that happens once in a decade. 1 out of 10 million flights. You have a better chance of winning the powerball than ever needing that chute. |

Ballistic parachute systems are actually really common in light (under 5700kg) aircraft. See [link to brsparachutes.com] For an example in use: [link to www.youtube.com] I imagine there is a whole set of engineer problems associated with airliners such as airspeed, altitude and how big a chute you'd need to slow something as big as a 747. |

You have a better chance of winning the powerball than ever needing that chute. How about if you had one thats already unravelled? For instance, imagine a bag, open end forwards, flat on the roof of a plane running the entire length, with a trigger that flicks the top part of the bag up in the air. It'd fill instantly with air. Wouldnt that work? even below 500 feet? |

(OP) User ID: 26618288 United Kingdom10/30/2012 04:30 AM Report Abusive Post Report Copyright Violation | Problem is, parachutes cannot be opened at a high speed. Quoting: Anonymous Coward 26615942 When military aircraft is dropping paratroopers, the pilots have that airplane one notch above "stall speed", the speed at which the wings no longer produce lift. Maybe the parachute has limitations that could be overcome using variations on my idea. Cone shaped ones maybe, with an open end @ the top. IF you could open and close the hole in a sphincter like fashion, you could even control decent velocity. |

What you decribed here is undoable, for many reasons. Airplanes are not something that you can just add stuff to, on the fuselage, like you add luggage on a car. |

Maybe the parachute has limitations that could be overcome using variations on my idea. Cone shaped ones maybe, with an open end @ the top. IF you could open and close the hole in a sphincter like fashion, you could even control decent velocity. First you need to find a material strong enough to handle slowing 950,000 pounds of airliner suddenly, while travelling at a little over Mach 0.8 without tearing or having the lines break. Then consider whether the structure of the aircraft can handle it (wing spars are strong, but the sudden g-force would be huge). IMO the aircraft would break up immediately. The only feasible approach I can think of is a set of smaller drag chutes to reduce the aircraft speed and then primary chutes say under 250kts and 10000 feet. I don't think it will work to be honest, it's great for light planes under 150kts though. (yes I have an aviation background btw). |

So it would not increase chances of survival enough to finance this idea. "Fortune, honour, beauty, youth are but blossoms dying.

| Anonymous Coward User ID: 1018225 United States10/30/2012 05:18 AM Report Abusive Post Report Copyright Violation | Why not design the big planes to break apart when the chute is deployed, kind of like crumple zones in cars? Everything breaks away when the chute deploys via the g force created by the drag of the chute? That would separate the passengers from the fuel source and engines reducing chance of fire. |

Ah well beaten to it. Surely the design and physics stay the same even if u scale it up? I'm sure its in the pipeline if its doable :) |
