The word "skydiver" is missing between "British" and "Adrian Nicholas".

This page is problematic because it defines "parachute" in terms of vertial parachutes for individual people, when the term has a broader meaning as a drag or lift producing device.

Anyone got better stuff?

Parachute are used in different contexts you're right, I think an expansion may be in order rather than replacement. The original definition is still the dominant one, with drogues etc. often used to describe other applications.

A parachute is also a smoking device commonly used for cannabis...AKA 'lung', it is based on the principle of using a sealed plastic bag to draw smoke into an airtight bottle, by pulling the bag away from the bottle it is attached to. Smoke is pulled in through the neck of the bottle, the only open area of the device. The cap of the bottle is then removed, and the smoke is inhaled by the user, causing the bag to be pulled back inside the bottle.

You may want to add a section and have it disambiguated for this, I'd rather not, let folks find it under drug paraphernalia somewhere, some slang term for a bong in a bag is not justification for a whole section. This is not a dictionary, it's an encyclopedia.

What about other definitions of "parachute"? For example, some people take drugs by wrapping them in tissue paper and then swallowing them, and they call that process parachuting. If this is too uncommon a usage of the word, that's no problem.

You answered your own question. Definitions belong in a dictionary. Articles belong in an encyclopedia. If you want to write an article describing that particular practice, then you'd want to creat a disambiguation page the allows the reader to branch off in one direction or another.Rklawton 22:49, 4 February 2006 (UTC)[reply]

Aren't the lines connecting the load with the canopy called shroud lines? Leonard G. 05:24, 4 May 2004 (UTC)[reply]

Yep. Trekphiler 13:22, 3 December 2005 (UTC)[reply]

I think this applies principally rounds, modern squares tend to be called suspension lines I think, but I'm not a rigger.

I am a rigger and I've never heard the lines on a modern sports parachute called "shroud lines". "Suspension lines" or just "lines". "Control lines" or "steering lines" for steering lines. Military applications, roundies and cargo parachutes may have different terminology.Skydiver 09:58, 21 January 2006 (UTC)[reply]

I believe "shroud line" is an antiquated term still used by the general public and is typically not used in either the military or the sport parachuting community. In my many years as a skydiver/BASE jumper and as an aircraft mechanic in the military, I have never heard the term used in a professional setting. Brienh 04:31, 26 March 2006 (UTC)[reply]

By no means am I trying to accuse the contributor of anti-Muslim attitudes, but I'm just curious why the mention of the guy in Constantinople is referred to as "Another Muslim", rather than something like 'someone else'.. pomegranate 14:55, Jan 22, 2005 (UTC)

The primary source simply describes him only as a Saracen. If it had given some clue as to his national heritage, I would have said something like, "an unnamed Turk," or Arab, or whatever. As it was though, he was described only by his religion, or I went with that as the most specific description possible. It is no disgrace to count an early pioneer of flight among one's co-religionists, even if they were unsuccessful. Shimmin 16:18, Jan 22, 2005 (UTC)

"The first successful test of a parachute was made in 1603 in Bratislava, Slovakia by Štefan Banič." The achievements of Mr Banič are dated to 1913 in the very next chapter. Also his personal article states that he conducted his tests in Washington DC. Not to mention the fact that neither a city called Bratislava, nor a country called Slovakia existed in 1603.Amanitin (talk) 09:48, 6 July 2008 (UTC)[reply]

I find the text reference in the Chinese history book and I will list it here. “瞽叟尚复欲杀之，使舜上涂廪，瞽叟从下纵火焚廪。舜乃以两笠自捍而下，去，得不死。”——《史记·五帝本纪》--Waltigs (talk) 03:12, 22 October 2008 (UTC)[reply]

The records section contains conflicting units: "According to the Guinness book of records, Eugene Andreev (USSR) holds the official FAI record for the longest free-fall parachute jump (without drogue chute) after falling for 100,380 ft (24,500 m) from an altitude of 83,523 ft (25,457 m) near the city of Saratov, Russia on 1 November 1962.". The numbers for feet and meters don't match. It seems most likely that the first value of 100,380 ft should be 80,380 ft, to match the meters value, and be smaller than the "from a height of" number. I am not making the edit, as I am not an expert here. —Preceding unsigned comment added by 155.31.21.229 (talk) 23:39, 7 December 2009 (UTC)[reply]

I doubt they exist except for science fiction, but if they have been thought of, they've probably been tried in one form or another... I'm thinking of some movie where freefalling people had rockets that shot down beneath them and exploded at the point where they would land, with the explosive gases filling balloons for them to land on. In video games they have "dropship" type things where the people are rapidly decelerated by a long tube they ride in, which hits and sticks in the ground, etc. etc. Was anything like this ever tried by crazy experimenters? I guess those ziplines that they use to drop troops out of helicopters count... - Omegatron 19:44, Feb 9, 2005 (UTC)

Hi does anybody know what factors affect the stability of a parachute? Thanks

Why is necessary to drop huge bombs with a parachute? Is there too much heat generated from drag otherwise? Twinxor t 22:29, 6 Jun 2005 (UTC)

It's to slow-down the descent of the bomb (especially airburst nuclear weapons, which explode some distance from the ground) thus delaying detonation and giving the dropping aircrat time to get to a safe distance from the explosion. Ian Dunster 10:59, 20 Jun 2005 (UTC)

It's also been used to slow frag bombs so the burst doesn't hit low-flying aircraft, such as the WW2 "parafrag" or (Mk82?) hi-drag. Trekphiler 13:22, 3 December 2005 (UTC)[reply]

When I read:

The average skydiver in the U.S. makes about 150 jumps per year and will leave the sport before the 5th year.

I wonder how expensive this hobby gets. But not sure if prices should be included on Wikipedia.

About $20 a jump once you're qualified, maybe $3-6k for a gear and about $2k for student training to get you started. But you can jump rental gear etc.

WpZurp 14:24, 6 August 2005 (UTC)[reply]

And I wonder whether such temporary and unsourced information belongs to Wikipedia. Pavel Vozenilek 23:34, 6 August 2005 (UTC)[reply]

I think this is info from the USPA, it may be unsourced in the article but it may not be inaccurate. I did not add it, and it does seem of limited value, it should be attributed at the very least.

The pricing information is accurate as of 2005. However, I think what he means is that current price information probably doesn't belong in an encyclopedic article. It will get dated too quickly. If this information is important, then perhaps average cost per jump for each decade of sport jumping might be interesting. On the other hand, price per jump probably reflects inflation and cost of living increases. Readers can get that sort of information from articles about economics.

This was the original:

"The first military use for the parachute was for use by artillery spotters on tethered balloons in World War I. Hydrogen balloons used for spotting were easy targets for enemy fighter aircraft and were difficult to escape from while on fire. To avoid interception, observers would jump from their balloon and descend by parachute as soon as enemy aircraft were seen. The ground crew would then attempt to retrieve and deflate the balloon as quickly as possible. Aircraft crews, however, were forbidden from carrying their own parachutes. Having parachutes onboard was believed to encourage the unnecessary abandonment of expensive aircraft during flight."

I corrected this. Observation balloons were extremely tough, well-protected targets. And it wasn't an issue of how costly the aircraft were... Trekphiler 13:25, 3 December 2005 (UTC)[reply]

Weren't parachutes used with observation balloons during the American Civil War? Rklawton 23:03, 4 February 2006 (UTC)[reply]

This article is already 17Kb in size. Adding information about all possible parachute system components would probably make the article too long.

In any case, the "Design" section needs to be re-written; it has information about cargo, sports, aircrew and military parachutes all lumped together. The designs of the different kinds are completely different.

Maybe the "Design" section could be split in to an article of its own, with sections called "General", "Cargo", "Sports", "Aircrew" and "Military"?

Don't merge ripcord, there are many links to components, like slider and 3-ring release system and they should remain separate. Merging like this is a rather silly suggestion, it is useful to have a section of a ripcord for search purposes and additional detail without making the original article too turgid. On the rewrite of the design part, there are only a couple of main designs in use with common components, sure some details change between applications but but it ain't that bad. It really depends how exhaustive you want to be. Rounds are used for people and cargo, and squares are now being used for cargo delivery using GPS. The main differences for the purposes of description lie in the harness and deployment systems (and the scale of things). I'd suggest some restructuring rather than a total rewrite if you insist. Maybe an applicatiosn section? Suggestions?

I've re-organized the Design-section. Very little information was removed, and a few sentences were added here and there. Someone who knows about cargo-parachutes should include a section about those. Skydiver 10:50, 9 December 2005 (UTC)[reply]

I added a bit on deployment systems and switched out one of the images, not because it was better but because the same image of a guy under a round was used twice. Now there's a picture of a C-130 airdrop from dod.mil.

This article could benefit from a photo of a folded-up parachute in its pack. TerraGreen 17:23, 22 December 2005 (UTC)[reply]

I'll add one shortly Rklawton 23:03, 4 February 2006 (UTC)[reply]

The section on the paracommanders (or whatever they are called here - in 20 years of skydiving I never heard that term used) appears to conflict with what I had been told about how they work. I was under the impression they were smaller because of the lift generated by air flowing over the wing-shaped upper surface, not due to increased drag as stated here. Given that they have much less fabric, the claim that they generate more drag seems suspicious. Maury 13:35, 6 February 2006 (UTC)[reply]

I seem to remember hearing the same thing; that the distorted shape of a PC produces lift and therefore slows down the descent. The pulled down apex would increase vertical drag, but not the holes! I've removed the sentence. I haven't included anything about producing lift because I'm not sure about the details. Someone who has Poynter's manual handy should check it out and add the relevant information while citing the source. Skydiver 13:59, 15 March 2006 (UTC)[reply]

"Parachutes (commonly called "drag 'chutes") can also be deployed from a jet aircraft horizontally from the tail cone at the point of touchdown or shortly afterwards to shorten its landing run, for example if landing on an aircraft carrier ... "

Please provide a citation in reference to use of drag chutes on aircraft carriers. Having worked as an aircraft mechanic (F4-N) in the Marine Corps, both shore based and on an aircraft carrier, I have never witnessed a drag chute used in this way. Aircraft recovery on a carrier is accomplished with the use of a tailhook and arresting cable system. In the event of a failure of the tailhook, a 'barricade' is stretched across the flight deck to bring the aircraft safely to a stop.

Also, it should be mentioned that some aircraft, specifically the F4, use a drag chute for spin recovery in addition to shortening landing rollout distance. Brienh 04:31, 26 March 2006 (UTC)[reply]

I've seen BASE rigs with mesh sliders, but I've never seen a skydiving sport reserve with a mesh reserve slider as claimed in the article. Has anyone? Rklawton 00:22, 24 June 2006 (UTC)[reply]

I've never seen one either. Many reserve sliders have a large hole in the middle though. Then there is the "bikini" slider which has two triangular holes. Skydiver 16:54, 13 July 2006 (UTC)[reply]

I've never seen a bikini with two triangular holes, but I'll keep a lookout. Rklawton 17:02, 13 July 2006 (UTC)[reply]

I can't find anything about the speed that a parachute slows you down to.80.109.79.136 16:05, 28 August 2006 (UTC)[reply]

Speed will depend on what you mean by parachute (which kind and what size), weather, and weight of the parachutist. Rklawton 17:33, 28 August 2006 (UTC)[reply]

Bothered by the wording of the "space" section under usage. Currently it reads: "Parachutes can be also used for soft landings on other celestial bodies. However they do not work on celestial bodies without an atmosphere, such as the Moon. For a soft landing on Mars a parachute alone does not reduce the sinking speed in the necessary intensity and there are always brake rockets or airbags necessary for a soft landing. Soft landings on Venus do not require a parachute, because the extremely dense atmosphere of Venus breaks the descent enormously, even without the use of a parachute. Because of the high temperatures and the limited cooling possibilities of probes, the last part of the descent to Venus is done without a parachute. Landings on Saturn's moon, Titan, are possible using only a parachute." [unsigned]

It certainly seems reasonable that a parachute could not work on the moon, but the wording ("they do not work") implies that this has been tried. Has it? (And, doesn't the moon actually have a very thin atmosphere?) Similar assertions are made for various planets here without clear indications of what is theoretical and what is proven fact.

On Venus, the atmosphere "breaks" the descent; I'm pretty sure that should be "brakes."

What is the meaning of "Because of the high temperatures and the limited cooling possibilities of probes, the last part of the descent to Venus is done without a parachute"? I would think the point of this sentence is that the last part is done with a parachute; otherwise I do not understand the statement. (And is this actual or theoretical?)

None of these statements are cited, nor indeed do I believe there are any citations in the whole article... Darentig 15:40, 1 September 2006 (UTC)[reply]

Somebody changed the article and it doesnt make sense now (though it is funny...)

"A parachute is a very unsafe fabric device used to kill the person trying to break through an atmosphere by creating drug. Parachutes are generally used to speed the descent of a person or object to Earth or another celestial body within an atmosphere. Drogue parachutes are also sometimes used to aid horizontal acceleration of a vehicle (a fixed-wing aircraft or space shuttle after running very fast, or a drug racer). The word parachute comes from the French words para,kill or torture, and chute, the fall. Therefore parachute actually means "kill the man in this dang thing". Most modern parachutes are classified as semi-rigid wings, are quite effective at killing, and can be flown as a glider.

Parachutes were once made from silk but these days are almost always constructed from more durable woven nylon fabric, sometimes coated with a - silicone - zero porosity coating to improve performance and consistency over time. Originally silk was used for parachute suspension lines, but was replaced by nylon during the Second World War. When square (aka ram-air) parachutes were introduced, manufacturers switched to low-stretch materials like Dacron or zero-stretch materials like Spectra, Kevlar, Vectran or high modulus aramids. Kevlar is rarely seen except on reserve canopies."

This is very strange. The COMAP Math Modeling contest, for the high school level is a competition offered in November for high schoolers in which a group of up to 4 students spends 36 continuous hours working on/modeling a mathematical problem.

I think a separate article is called for. Along those lines, lets examine a general re-organization of these topics while we're at it.

I made a number of small changes to the punctuation and text of this section, hoping to make it clearer, and more grammatically correct. As I know nothing (apart from this fine article!) about parachuting, it might be good if one of the primary contributers were to review my changes for factual accuracy. For example, it wasn't clear to me from the text whether both the leading- and trailing-edge ellipticals were used by sports parachutists, or just the trailing-edge ellipticals. (It wasn't clear what the word "these" in that paragraph referred to.) Fagiolonero 06:39, 19 March 2007 (UTC)[reply]

I have a question about factual accuracy of a small change I made to this section: At the beginning of the second sentence of the first paragraph, is it correct that the problem described regards overly rapid deployment, as I've written? From the text that follows, this seems clearly to be the case, but I thought I'd ask to be sure. Fagiolonero 07:06, 19 March 2007 (UTC)[reply]

Rounds are rarely used by skydivers these days.

Why?

A "Mae West" is a type of round parachute malfunction which contorts the shape of the canopy into the appearance of a brassiere, presumably one suitable for a woman of Mae West's proportions.

This makes no sense.

Anyhow I came here to learn, so I don't know anything about this subject otherwise I'd fix it. -Rolypolyman 04:21, 11 November 2007 (UTC)[reply]

The Mae West bit makes perfect sense to me. The malfunctioning chute looks like two puppies fighting in a bag, ones of which you don't get many of to the pound. Easy. Maikel 14:02, 14 November 2007 (UTC)[reply]

It would be interesting to include a short list of characteristic jump heights, i. e. for military parachutists, hobby parachutists, high altitude, BASE, supply drops, etc. Thanks. Maikel 14:02, 14 November 2007 (UTC)[reply]

I question the accuracy of saying that the chute on the space shuttle is for stability.

It says Venetian inventor Veranzio jumped out of the tower in Venice. That's not correct, it was a croatian inventor Faust Vrancic:

Other early inventors designed parachutes, including Croatian Faust Vrancic who constructed a device based on Da Vinci's drawing. Faust Vrancic jumped from a Venice tower in 1617 wearing a rigid-framed parachute. Faust Vrancic published Machinae Novae, in which he describes in text and picture fifty-six advanced technical constructions, including Vrancic's parachute called the Homo Volans. —Preceding unsigned comment added by 89.164.3.153 (talk) 11:43, 22 April 2010 (UTC)[reply]

From here it looks like the "para" in parachute comes from the Latin "parare" meaning "to prepare" not from the Ancient Greek "para" meaning "against". So while both sound right, I think the Latin word is not related to the Ancient Greek word. If this is correct, Wiktionary is also wrong here.

Something is not right here, but I am not a parachuting expert. Lattemann died in 1894, and him and Paulus were jumping mainly at the end of the 19th century. How could they have made Kotelnikow's invention popular? Paulus actually did serve as a parachute advisor to the Germans during WWI, so she was active after 1911, albeit in a passive role. As stated in Lattemann's Wikipedia entry, he and his wife used folded parachutes that were carried in a "bag". What precisely is the technological advance introduced by Kotelnikow? Ondundozonananandana (talk) 21:15, 6 December 2010 (UTC)[reply]

I seem to recall somewhere a constricting ring used on the lines of a high-speed chute, so that the sudden opening of the chute does not shock the plane, snap off the lines, or tear the chute.

Basically the ring starts out close to the parachute and holds it mostly closed at higher speeds. As the aircraft or jumper slows, the ring works its way down the lines towards the aircraft/jumper allowing the chute to open wider until it is finally fully open.

I don't see any discussion of this in the article, and I am wondering if anyone else knows what this is called. DMahalko (talk) 16:57, 14 August 2011 (UTC)[reply]

Note: I am writing this critique for a history of technology course at the University of Maryland.

This article is extremely well-written. It is clear that many contributors have worked on this article over time to make it so useful. It is free from any spelling or grammatical mistakes and is written in a professional manner. The content discussed is in-depth but easy to read and understand, making this article appropriate for most readers. It is a complete article and covers every point it should. The page integrates many pictures; some showcasing different types of parachutes, and others helping to illustrate the history of parachutes. These pictures are extremely helpful and are small enough to prevent any clutter on the page.

This article is well-maintained. It doesn't suffer from too many contributions. The most recent changes to this article include adding pictures and fixing typos. Because it is already complete and so well-written, there aren't any serious changes anymore that would seriously change the article.

The article is well-organized. It first explains the history, which is also split up even further by time periods, The abstract provides a brief definition, history, and a history of the word itself. After that is information about different types of parachutes, safety, danger, and records. The article wouldn't make as much sense if these sections were in a different order. This organization provides a flow which better informs the reader about the topic of parachutes.

Most of the sources check out as reliable. The first and most used source is an article from Johns Hopkins University about the history of the parachute. Other reputable sources from the list include BBC, scientific journals, and other academic articles. The information in this article was all, or just about all, from legitimate sources.

As a whole, this article was extremely well-written and presented. It doesn't have any weaknesses and in my opinion is a good example of a quality Wikipedia article.

This article lacks technical detail on design of the parachute to obtain the desired results. The calculation of the different forces involved during the deployment of the parachute and how it affects the terminal velocity of the paratrooper, its directionality, the effect of air turbulences on parachutes of different shapes and sizes, etc. Wikipedia is supposed o be a basic technical reference, it should make emphasis in the mechanistic aspects of what is described. 37.133.53.224 (talk) 01:23, 22 January 2015 (UTC)[reply]

Goodmorning, i saw you turned my changes in the previous version, saying Veranzio was croatian. Actually he was born in what nowdays we call Croatia, but in that time Croatia didn't exist. He belonged to the Veranzio family, one of the noble venetian familyin Dalmatia. He also moved to Venice when he was still a child and he studied in Padua. He wrote his books in Latin (like the mist of the books in that time) and italian. So i think is not correct to say he was croatian, and the information dosen't find a match in his own wikipedia page. I suggest to correct the "parachute" page turning again "venetian" or, better, "Dalmatian" . If you disagree we can discuss on this page. Alb89vit Alb89vit (talk) 09:12, 13 November 2015 (UTC)[reply]

Our article on Fausto Veranzio currently says his nationality was "Croatian". If you believe this is inaccurate, I suggest you discuss this at Talk:Fausto Veranzio. I notice this has been discussed before, both on this page and at Talk:Fausto Veranzio/Archive 1#Venetian or Croatian. Burninthruthesky (talk) 10:33, 13 November 2015 (UTC)[reply]

Need section on Uses, eg a section on use for airdrops (cargo delivery by parachute). Also for rocket recovery, eg for STS SRB recovery, and aircraft emergencies. The designs will vary by intended use. - Rod57 (talk) 12:07, 9 June 2020 (UTC)[reply]

The article and image credit says that the first parachute was drawn by Taccola. It then says that it was drawn in 1470. This is not possible, since Taccola had died several decades earlier. It is highly likely that someone got confused, because the folio it was found in also contained Taccola's work. The folio was combined from the works of two separate people. These have been identified as Taccola (who was dead before 1470) and Francesco di Giorgio Martini (who was alive during the 1470s). The drawing was found in the section that was identified as being by Francesco di Giorgio Martini, and was drawn in the style of Francesco di Giorgio Martini. It was dated due to its location between pages in that work which had dates written on them.
