Life Support Atomic Rocketsed note this more or less comes to the same conclusion as Ian Malletts analysis aboveBrian Davis. This came up in a different newsgroup, and upon trying to answer it I. Im not sure the original group really cares, but folks. Lets say you have a person named, lets say, Callie standing in.

But anything major Or does Callie really fully decompress in the. One interesting. artifact of my calculation is that Callie takes a sharp jump up in. Im not. as worried about that because in the real situation, the doors would. PS Id love to take the rate of the doors opening i. I think I have to. Robert Heinleins Starman Jones they have to do burial in space. They pressurize the airlock to ten atmospheres in order to have enough pressure to blow the body out the airlockJohn ParkI havent verified your numbers, but for a quick sanity check, theres about. If you really want. I think you should start her. Tim LittleBrian Davis. She really only accelerates for the first couple seconds, after that. Yes, thats about right, if the door opens outward and sticks at a. Though actually Id be very surprised to see an airlock. If it did open outward, and was free to swing open wider, consider. Pa pressure acting on the inner surface. It will. accelerate open very rapidly indeed probably on the order of tens of. Though even in that situation, Id guess Callie would exit the airlock. George Bush Falling Bubbles Game here. Brian Davis Or does Callie really fully decompress in the airlock, and gently. Yes. Brian Davis if the breach is one entire side of your airlock, I think I have. Sort of. The rarefaction front will propagate inward at the speed of. The temperature behind the front will be some fraction of the. Id guess about 45 from one thermal degree of. The relation for adiabatic expansion then gives a pressure behind the. That will exert a lot of force on Callie, but only for about 2. Dr J. R. StocktonBrian Davis Lets say you have a person named, lets say, Callie standing in. The bad. girl opens the large doors at the end, blowing the lock it starts. Atm. What happens to the helpless heroineAt worst, approximately, and assuming a heroine of only moderate size. The heroine, being around a thousand times more dense. A worst case approximation is that a transition between 1. Pa and 0 Pa. propagates past her at 3. So, per square metre, she gets 1. N. for a duration of T3. T is her thickness in metres. Her mean. density will be, of course, 1. SI units, so per square metre her. T so her change in speed will be 1. T3. 30 1. 00. 0T. One cannot recommend, for the usual purposes, a heroine who obstructs a. Tim Little Dr J R Stockton. A worst case approximation is that a transition between 1. Pa and. 0 Pa propagates past her at 3. So, per square metre, she gets. N for a duration of T3. T is her thickness in. The duration is much longer than that, since she is still in the path. Even though the. static pressure is at 0 Pa, it still has significant density. In particular, if c is the usual speed of sound, and v is the speed to. So the air rushing past her from further in the airlock will exert. So for a long airlock, her velocity. This is a fairly short airlock, but certainly longer than her average. John SchillingDr J R Stockton. At worst, approximately, and assuming a heroine of only moderate size. The heroine, being around a thousand times more dense. A worst case approximation is that a transition between 1. Pa and 0 Pa. propagates past her at 3. So, per square metre, she gets 1. N. for a duration of T3. T is her thickness in metres. Her mean. density will be, of course, 1. SI units, so per square metre her. T so her change in speed will be 1. T3. 30 1. 00. 0T. Ah, so if I hang a sheet of tissue paper just inside the airlock of an. ONeill habitat, and open the door, it wont go anywhere, right Because. Im thinking thats not right. Im also thinking that a propagating. What actually propagates, is a transition between air at 1. Pa, and. air at 5. Pa moving outwards at 3. And that transonic. If the geometry is cylindrical, I get for a standard heroine in a. Thats in the low velocity limit as. If the geometry is not cylindrical, it gets rather more complicated. Erik Max FrancisBrian Davis OK, so what did I screw upNothing, Id say. The ability for explosive decompression to push. Your results sound qualitatively.

Yes, decompression is dangerous, and if a. But theyre not. caused by the decompression It should be noted that an airliner at altitude is usually moving at a. The air. doesnt just simply leave as it would in a vacuum, or if it were a. From the point of view of the aircraft, the air outside has kinetic. If a large hole opens up, part of. Erik Max Francis It depends on how much air is in the vessel, how big the hole is, and. Sure, there are some cases where. But probably not in. Brian was talking about. Not that really helps her chances. Michael Ash The image of everything thats not nailed down flying out the door may be. Perhaps the most famous explosive decompression. Aloha Airlines 2. One flight attendant was thrown to the floor. A 7. 37 isnt particularly large but it would require substantially. A spacecraft. pressurized to 1 atmosphere should be a bit worse as well, since the. It should be noted that a small hole doesnt do this, because a small. A small. hole will leak, not cause a bang, and there would just be some wind. Thus the fears of instant death due to a gunfight piercing the hull are. I believe this is what Mythbusters investigated. But this is an entirely different scenario from opening a large airlock. Aloha Airlines flight attendant. Wayne Throop. Sure, but thats what being exposed to 3. Just the decompression, not so much. Its the fact that so much. The Mythbusters bit iirc was concerned with two aspects of a fairly. First, will it suck everything inside towards it, and. And they concluded, no and no. Of course, they were talking about. But I doubt things would be much different. An upper half of the hull peels away in a section tens of feet long. I doubt anybody will. Robert MartinuWayne Throop. And they concluded, no and no. Of course, they were talking about. But I doubt things would be much different. Later the episode they tested what a moderate amount of explosives would. The result was iirc a seat cusion sucked. Again its not the decompression. The Craziest Jump In Rally Kills Cars In Australia. The craziest jump in rally is a big statement. You have the famous jumps in Finland. El Brinco in Mexico. WRC Sweden has an award named Colins Crest for the longest jump on SS1. These are massive jumps, but they arent the largest or the craziest. Rally racing is unique in the world of motorsport. You race on roads that are normally open to theRead more Read Editors note We interrupt your regularly scheduled programming to bring you a special bout of insanity from friend of the site and crapcan racer hero, Bill Caswell, who is taking over for us this weekend. You need to go down to Australia for the craziest a jump thats on the Mineshaft stage of the Canberra Rally. Tile Creator'>Tile Creator. Although Minshaft really isnt a jump, its more of a cliff in the middle of the stage. Even at really slow speeds cars seem to fall right off this thing and explode on impact. It looks so dangerous that if this road existed in the United States they would have barricaded it decades ago. Heres another look at it from the bottom. I have yet to find a video of a car clearing this thing and landing without an explosion. Im not sure its even possible. Mineshaft has to be the craziest jump in rally.
