More than half a century ago, when I was in high school, we had a "science" assembly in the gym that was conducted by a former science teacher from our school. Maybe it was NSA or NASA or something (we had a lot of these things in Maryland in the 1960s), I can't recall. Well the "finale" of his demonstration show was a ram jet that he had mounted to a stand. He gave his patter and then he set off that jet and it went on for about 10 seconds. I think my ears bled. It was the loudest noise (in a gym, no less) that I have ever heard in my life before or since. After the screaming had died down, we walked out of the gym VERY quietly. I passed my principal on my way out. He had a look of fire and brimstone on his face. Needless to say, former science teacher was never invited back.
@HubbaBubba-s4b btch I'm currently in Ukraine while Russia attacking us, come here from your mom's basement and tell me in face that there's no such a country as Ukraine
@@basketballjones6782 It was 50+ years ago, my man, and I didn't take notes. Give me a break. All I know is that it was loudest thing I have ever heard in my life--and I've witnessed a dozen or more KSC rocket launches.
I would also point out that the recording *in no way reveals* how LOUD it is, they are absolutely incredible. Very mellow, but louder than you can possibly imagine.
Es ist immer wieder faszinierend was der menschliche Geist hervorbringt, erschreckend jedoch wofür die Dinge verwendet werden. Diese Geräusch hat viele Menschen vor langer Zeit in Angst und Schrecken versetzt. Technisch ist es an Einfachheit in der Konstruktion ein Hammer.
Duddel Bag ( Brumm Käfer), nannten es die Engländer als im Sommer '44 als die ersten V-1 Flugbomben mit diesem Antrieb über Südengland und London auftauchen. Militärhistorisch muss gesagt werden das dieses Gerät die erste funktionierende "Cruise Missale" der Weltgeschichte war.
Da stimme ich Ihnen zu. Es ist halt so. Wenn der Mensch Waffen entwickeln kann, ist er unheimlich kreativ. Wobei ich natürlich nicht vom reinen Triebwerk spreche.
German ingenuity at its finest 💪 The jet engine was developed simultaneously by the British too, but the german ones were far better, their planes significantly faster too, and it was a coaxial jet engine, compared to the british one. Frank Whittle said he respected his co-inventor
As a science class helper I had to start up a desk top size pulse jet at the end of class I disliked it very much because it was so ungodly LOUD !! You can’t wait to shut it off !!!
...indeed, it sucks its own flame backward into the engines combustion chamber to reignite the following load of ignitable fuel/air mix. In fact, that's the way it works. 👍🍻🤘
@@kweetniet1103 no it’s not. It’s not sucking its own flame. Pulse engines on each cycle push hot gases out of even the intake. The hot gas that remains in the chamber is what ignites the fuel air mixture . The atomised fuel ignites when contacting the hot gases Not flames. It’s not sucking the flame back in. That’s an illusion due to the wave of a vacuum being formed after each ignition:
Yeah guys this is why your seeing the flame like that. It's because of the frames that camera is taking. Like when you see a car wheel going backwards even though the car is going forward at 30mph.
Die Grundlage aller Abgasgeladenen 2 Takt Motoren ❤😁👍. Sehr schön,das sich jemand mit dem Pulsstraltriebwerk befasst und es der Öffentlichkeit zugänglich macht 😁.
Warum nutzte die V1 keine 2 Takt Motoren? Scheinen ja billig zu sein. Bei 4 Takt Motoren schmelzen die Auslassventile. Beim 2 Takter müsste die Schlitze an einer Stell liegen, wo der Kolbenring schnell drüber rutscht, sodass der und der Kolben zumindest nur kurz im heißen Abgaß-Strom liegen. Unterdruck vom Auspuff und Überdruck vom Fan spülen dann die letzte Hitze raus.
@@DuDarfstMichSiezen genau. Nagel mich nicht drauf fest,aber bis zu dem Zeitpunkt, als Kaaden den Resonanzkörper für sich und die 2 Takt Motoren entdeckt hat,waren die 2 Takter nicht "schwach" auf der Brust,aber eben lang nicht so Leistungsfähig.
I used to build little pulsejets and scrapyard-turbines back in the 90s, but I always dreamed of building an Argus replica ... I drew up a quarter scale version using miniture reed-plates decades ago, but never got round to actually building it (no idea if would work directly scaled down, but should be close). I'm amazed no one ever did it as far as I know.
My grandad said the scary part was when the V1 engine stopped making its noise... he never quite got over his feelings of animosity towards Germans I think.
A V1 killed my grandmothers aunt and cousin during the war. I think the v1 was far more scary than the V2, although the V2 made a much bigger explosion and crater. When you heard the V1 engine stop, you knew it was going to drop down somewhere close by.
@TheRealNeill It's crazy if they used the same power of explosives. I've seen both a v1 and a v2 at the imperial war museum in London, and the v2 is fkn huge lol. Over my local park there was a manor house that was damaged from a v2 that landed maybe 400 meters from the house. It apparently caused a crack all the way up the house from top to bottom at that distance. There is a small crater still remaining (about the size of a doodlebug crater) but the huge crater from the blast was filled in back in the early 50's I believe. I saw a huge crater on a Patrick Lancaster video in Russia where a Ukrainian tochka u rocket had hit a farmers field and i think it was a similar size to the craters the v2's used to make.
Yeah I think the V1 was more of a psychological weapon then a destructive one. It obviously packed a punch but same as the Stukas air siren it scares the living crap out of anyone hearing it
Herrlicher Krach !! Die Ringflammen am Anfang sind ja wohl Spitze. Später dann im kontinuierlichen Lauf sieht man die Frequenz, mit der der Schub zu- und abnimmt. Die Flamme schießt erst durch und fächerst sich weiter hinten auf, dann kommt sie näher und expandiert schließlich unmittelbar hinter der Mündung. Dadurch entsteht dort Unterdruck, der die nächsten Verbrennungen wieder normal ablaufen läßt, bis dann das ganze sich wiederholt. Die Verbrennung beginnt sich selbst zu blockieren - zumindest auf dem gezeigten Betriebspunkt. Aus meiner Sicht müßte der Konus schlanker und das Endrohr entsprechend kürzer sein, damit nach hinten der Widerstand geringer wird. Für das Flammenspiel gibt es jedenfalls 10 Extrapunkte.
the sound is scary sure , what scared the people of Britain the most was when the sound stopped , it meant it reached its destination and would plummet

Safety beer, very important.
Looks like the thrust is very small. Was it really able to puth V-1 in the flight?
Direkt ne Kanne Bier, macht sofort einen guten Eindruck!
