[edit] 'Simple device': incl engine?
"simple device" "constructed in around fifty man-hours of mainly sheet metal" -- does that include the engine?
- It was a very simple engine - so quite possibly, yes. Mind you' I'm only guessing that. Tannin
- Can't say for sure, either, but the V-1 engine was little more than a stovepipe with a valve on the front, a fuel injector, & a sparkplug. Trekphiler 21:58, 20 December 2005 (UTC)
Indeed, I added the shutters to the description. But I wondered about the rate of firing, said to be 100/sec. That certainly would produce a buzz - but despite its name, it actually uttered a sound much more like that of a fast two stroke engine, a puttering sound, and I wondered if /sec should have been /min? Help would be appreciated.
Fenton Robb 12:55, 24 April 2006 (UTC)
- I've heard recordings (though I can't remember where and I can't vouch for it being a real recording and not a simulation), and 100/sec sounds right. I would think that 100/min would be way too slow; the craft would have time to start falling between pulses. KarlBunker 16:58, 24 April 2006 (UTC)
[edit] Number of V-1's produced
From the entry: Almost 30,000 V1s were manufactured. 9,521 were fired at England. I have another figure: V1's launched against England, not including the V1's that landed short of their targets or fell into the sea = 10,753. It's doubtful that both are right. Can anyone provide a reasonably certain estimate?
[edit] Engine sound recording
The sounds stops, I suppose when the engine shuts off, but I do not hear the impact. This gives a feeling of the sample being a bit uncomplete. How long does that take? Perhaps too long for including that? - Patrick 11:38 Apr 11, 2003 (UTC)
I don't have a more complete recording but. I think it takes a long time before the impact (several minutes). But size of the file would not be a problem Ogg/vorbis is very good in compressing silence :). Ericd 11:46 Apr 11, 2003 (UTC)
- So the good thing is that you have time to look for cover, the bad thing that you may not hear it coming at all if you are near the place of impact. - Patrick 12:26 Apr 11, 2003 (UTC)
-
- The time delay wasn't that long, perhaps 10-15sec, from what I've read & heard. People uniformly heard it (I understand it was pretty loud, louder {or more piercing} than an aircraft engine); what was frightening was to hear it cut, since that meant it was about to hit. Trekphiler 07:32, 15 December 2005 (UTC)
Typically, they flew at about 1500 feet, but their behaviour was pretty unpredictable after the engine cut out. Some seemed to dive or even drop ballistically for about 7 - 10 seconds, while others would continue on their way losing height while gliding down to earth. I saw one cut out and then circle round the R. N. Hospital at Chatham for many minutes (it seemed like hours!) as it spiralled down. Fortunately, it missed the Hospital. By the look of them, they should not have been able to glide without power at all, but glide they did. Fenton Robb 17:48, 24 April 2006 (UTC)
It's great to have the sound recording here, but it's in a format that (it seems reasonable to presume) few people will be able to play. My system (Windows 2000, Media Player 6.0 and RealPlayer both installed) doesn't know what to do with it, and despite a lifetime spent working with computers, Ive never heard of .ogg files. (I don't play with sound much these days, I grant you. Stll, it seems like a reasonable random sample system.) Now sure, I could spend a few minutes and track the format down via a search engine, or ask around at the office and get a pretty fast answer, but I shouldn't have to do that. Wikipedia should make itself as easy to use as possible. Anyone want to add something like this:
- Media Files : V-1 engine sound (Wikipedia:Sound help)
(Linking, of course, to an appropriate page, which would link to a suitable download.)
Yes - Just what you asked for is in The Lambeth Archives with a lot of detailed information about where the bombs fell. I have added a 'external link' at the bottom of the article. Fenton Robb 17:48, 24 April 2006 (UTC)
Well Ogg file are a full free software alternative to MP3, they seems accepted as the standard for Wikipedia. I will start an help page and upload the codec. Ericd 15:09 Apr 11, 2003 (UTC)

- Hi Tannin is the sound OK now ?
- Ericd 15:53 Apr 11, 2003 (UTC)
[edit] Added to WP:Brilliant prose
I added this page to Wikipedia:Brilliant prose
Waoooh my visage turns red ! Ericd 15:51 Apr 11, 2003 (UTC)
- Having contributed a fair slab of it myself, I can only completely agree with you that it is indeed "brilliant prose". :) Tannin
[edit] V-1 firing video clip pointer
Survival Research Labs is a performance art group in the San Francisco Bay area that uses a V1 in some of their shows. They have a 24 MB mpg video accessible from their website where you can see and hear the engine. The clip ends with an amusing visit from the fire department. Mark Pauline, the leader of SRL, explains in the video how they replaced some broken valves on the V1 by following the original German design, except using nickel valves instead of stainless valves. I was at a show in Berkeley tonight where they fired it. Email me if you want to see any of the video I shot with my little Canon S400 camera. RobertStewart 05:50 Nov 13, 2003 (UTC)
I posted edited versions of the videos I mentioned above on my blog quite a while ago, but forgot to update this page. Let me know if you want a copy of the original. My email address can be found on my website. RobertStewart 08:11 May 1, 2005 (UTC)
[edit] [Ff]lying [Bb]omb capitals?
Shouldn't "V1 flying bomb" be written as "V1 Flying Bomb", since it's used grammatically as a proper noun, like De Havilland Mosquito? Or not? I get confused about this (see my talk page) ( 09:06, 14 Dec 2003 (UTC)
In any case the article title is inconsistent with usage within the article ( 09:06, 14 Dec 2003 (UTC)
- It's ambiguous, since "flying bomb" is a generic term that describes many similar weapons (see flying bomb), but the term was first used in English to describe this particular weapon. Most usually in English, the weapon is simply called the "V-1" (or V1 or V 1...), and in this sense, "flying bomb" is not a proper name. Since the original (German) term for the weapon doesn't even have a name, I think that "flying bomb" is more appropriate --Rlandmann 09:20, 14 Dec 2003 (UTC)
[edit] von Braun at Peenemünde
Wasn't Wernher von Braun also involved in some way at Peenemunde ?
-- Kim Bruning
- Indeed, almost all the time, but not at all with the V-1. Rockets proper were von Braun's endeavour; see V-2 rocket. --Wernher 20:15, 22 Jan 2004 (UTC)
[edit] Good wiki process example!
This page is a really good example of the wiki process at its best. Lots of contributors, and over time it has turned into a really comprehensive article. It could perhaps use a very gentle copyedit to make it flow more smoothly (this is what always happens to multi-author documents - they get disjointed), but overall ... great work, team! Tannin 14:16, 5 Feb 2004 (UTC)
[edit] 'V-2' hyphenated, 'V1' not?
I just wonder about the title of this article vs the V-2 one. In the three books on the subject that I possess, the usage seems to be the hyphenated version for both 'Vergeltungs'-weapons. I actually think this is more typical of German language usage as well. Therefore, if no one objects carrying convincing arguments, I will rename this (the V-1) article (by moving it) to 'V-1 flying bomb'. --Wernher 22:37, 10 Aug 2004 (UTC)
- Well, as I've not got heaps of (negative) comments so far, I'll ask an admin to fix the move (renaming) to 'V-1 flying bomb' (couldn't myself due to a redirect already bearing that name). Now's your last chance to speak up... --Wernher 23:31, 14 Aug 2004 (UTC)

- There doesn't seem to be consensus in the sources I've seen; hyphen or no seems to be based on the author's preference. Hyphenated seems to go to the convention used in aircraft, as in P-38 (pursuit 38). My own bias is for hyphenated. Trekphiler 07:36, 15 December 2005 (UTC)

[edit] Is the description of the guidance system correct?
My great-uncle gave me a set of books about WWII and (being a tech geek even when I was a kid) I was fascinated by the diagrams and description of how the V-1 knew when it was over its target. Here's the way the book explained it:
There was a small propeller on the nose, connected to a long screw thread going back inside the missile. On this thread was a washer, and at the back end of the thread were two electrical contacts.
As the missile flew the airflow turned the prop and hence the threaded shaft; the washer would be wound along the shaft as it turned. When it reached the electrical contacts it would make a circuit, which energized a solenoid attached to a small guillotine. This guillotine would cut through the fuel lines, stopping the engine, and the missile would then dive.
At the launch site the engineers would preset the starting position of the washer on the shaft according to the known distance to the target and an estimate of the headwind. It sounds very rough-and-ready but it was accurate enough.
- The description's pretty accurate - the only error is the often-quoted part about the guillotine cutting the engine's fuel lines to stop the engine. Actually the guillotine was used to cut the elevator control cable (there was only the one cable as the elevator was spring-loaded to the down position, i.e. to give 'up' elevator the cable pulled and to give 'down' the cable was slackened) and when the air-log propeller fired the guillotine it was this control cable that was cut - the sprung-elevator then went into the fully-down position which put the V-1 into a sudden dive. The abrupt negative-G then caused the fuel flow to cease which stopped the engine. Ian Dunster 11:53, 15 Jun 2005 (UTC)
- On reading this article, I found myself asking "but how did they control when the bomb should dive??". So I've created a section about the guidance system, based on what you've written above. Hope this is okay! Mikecron 00:33, 15 December 2005 (UTC)
[edit] "although not always with the device buried deep enough to increase the effect of the blast."
Long ago, I read that the V1 was more effective than the V2 because the blast area was not reduced by its being buried. It did not usually hit hardened targets.
[edit] Inconsistancy w.r.t. Barrage Balloons
There's a statement: "half of those (3,876) landed in the Greater London area. An almost equal number were shot down or intercepted by barrage balloons." ... implying 3000+ hit by destroyed. Yet, later we have, when talking baout barrage balloons ... "and fewer than 300 V-1s are known to have been destroyed by hitting cable."
Anyone have a definitive answer? I suspect the latter is, but don't know. --Anonymous
- The prose might be somewhat unclear. According to this report, "although guns and fighters destroyed most of the V-1 bombs (1,878 and 1,846, respectively), balloons were credited with 231 'kills'." Thus the first of the statements you're referring to should be more like "An almost equal number were downed by the combination of fighters and barrage balloons." --Wernher 13:53, 6 December 2005 (UTC)
[edit] Diversion & casualties
It's widely believed XX Committee's efforts led to fewer casualties (I even believed it), but I read recently (I wish I could recall where...) diversion moved avg p.o.i. from rich parts of Lon to poor ones, & losses didn't change. (Given greater pop density in poor ones, it might even be they went up; the source didn't suggest it.) It's N a settled ish... Trekphiler 07:42, 15 December 2005 (UTC)
See R.V. Jones in Most Secret War page 422; they decided to ignore Herbert Morrison’s instruction, while he was chairing cabinet, that the deception/diversion would be an interference with Providence (his constituency was Lambeth, and Morrison thought it was an attempt to keep the V-1s away from the rich civil servants in Mayfair etc). But Jones worked out it would save lives, even though it was moving the mean point to South London esp. Dulwich where his parents and old school were. He later calculated that the deception saved 2750 more killed & up to 8000 seriously injured. Will add this to the section soon. Hugo999 07:31, 13 March 2007 (UTC)
[edit] Credits
The article puts Berry's score at 59; I've seen 60 (somewhere...). Also, who were the others, & what squadrons were they? Trekphiler 07:51, 15 December 2005 (UTC)
[edit] Spotting
The article claims the pulsejet was audible @16km; @night, I'd say the visibility of the exhaust plume was more important, N? How far was it visible from? Trekphiler 07:52, 15 December 2005 (UTC)
[edit] Development
Not sure if it belongs here, but... Loon inspired trials of Regulus I (aboard Tunny & Barbero) & Regulus II (Grayback & Growler, making Grayback first purpose-built SSG). Halibut would have been first SSGN, but Regulus II was cancelled, first. Trekphiler 08:09, 15 December 2005 (UTC)
[edit] Casualties due to V1
According to the Polish Wiki, the V1 was responsible for 5500 deaths and 16,000 wounded in London. I don't know what the source for these stats is, but thought it might be good to include'em.radek 08:47, 18 March 2006 (UTC)
- An article on the BBC website fits with those rough figures, but a source should be found.GraemeLeggett 10:51, 18 March 2006 (UTC)
R.V. Jones in Most Secret War page 423 quotes the Official History “The Defence of the United Kingdom” as 8617 bombs launched, 2340 reached London Civil Defence Region causing casualties of approx. 5,500 killed & 16,000 seriously injured. He says the deception saved up to 50% say 2,750 more killed & up to 8,000 seriously injured, by estimating that while on the first 24 hours of the main campaign (June 1944; 2200 hours 15th to 2200 hours 16th) about 30 of the 90 plotted fell inside built-up areas, if the pattern was shifted NW by about 4 miles then about 45 or +50% would have fallen in built-up areas. Hugo999 08:50, 13 March 2007 (UTC)
[edit] List of V1 falls
Is there a definitive list of all the sites where V1s (and V2s for that matter) fell anywhere ?
[edit] rv: vandalism
Apparently some anonymous bright-butt decided to edit the page as follows:
"The codename Flak penis Gerät 76 was somewhat successful in disguising the nature of this device and it was some time before references to p3n15 were tied to the V83 pilotless aircraft (an experimental V-1)".
The vandalism occured at 12:30, July 6, 2006 by 82.110.219.14 .
Page reverted to previous state, since no changes happened inbetweeen vandalism and the current state. --Stealth 18:51, 6 July 2006 (UTC)
[edit] Harmonised 20mm cannons
I was reading this, and I was wondering, what does it mean to harmonise cannons to 300 yards? The aircraft left wing cannons and the right wing cannons arc of fire crosses 300 yards in front of the plane --Denniss 17:26, 27 August 2006 (UTC)
It would be helpful if that explanation was in the article itself.
[edit] Cruising Height?
Need to specify consistent Cruising height - The V-1 has several heights given, Under:
- Description - 100 to 1000 m (300 to 3000 ft) – it would not cruise at 100m???
- Countermeasures - 600 to 900 m (2000 to 3000 ft)
- Specifications - 3050 m (10,000 ft) Is this a max not cruising height? As 10,000 ft is a rounded figure it should be converted to 3000 m. Hugo999 23:02, 13 March 2007 (UTC)
