V2 Rocket propellant injector

The liquid propellant injector head of the V2 rocket engine was a masterpiece of the era's engineering and the embodiment of numerous technological breakthroughs. The record for size and power, established over 80 years ago by the EW A4's engine, has long since been surpassed. But it still holds the curious distinction of being one of the most complex rocket engines ever built. And they were one of the most produced and successfully flown large liquid propellant rocket engines in history. And yet the engine used a makeshift assembly of 18 mixer cups, each delivering about 1.5 tons of thrust, that was more appropriate to a laboratory test prototype than a mass production model to be used in the white heat of combat. The German technicians responsible for the engine only intended to employ this solution as a workaround while they quickly developed a more straightforward propellant injector system, that was vastly easier to manufacture and assemble.
But it was not to be. Their chief combustion expert, Walter Thiel, was killed in the early morning hours of 18 August 1943 when RAF heavy bombers destroyed much of the residential area of the Peenemünde weapons research complex. No further development of the injector head was made until after the war when the US and USSR adapted and progressed the A4 project for their post-war military and civil space exploration purposes.
The precise 3D model used in this video is by Alexander Savochkin and is based on the original engineering drawings.

Didn't expect to see such interesting information in a YT short of all places.

We brainstormed it, and this was the nearest we could get to a cute cat video. KR RJD A&NTV

I would love to see the flow simulated through that nozzle assembly.

[@hamishwsmacdonald]

The same guy demonstrates water going through these nozzles at 15:00 kzbin.info/www/bejne/fZiTq4uwo7pmis0

So much detail and craftsmanship just to get blown up

[@kokokoko886]

Whoever made this must be showering staring at shower head.

Cool, rocket engines are awesome

I need to start saving up my used Nespresso cups!!🤣🤣👍

[@Danteelias08]

I have seen all your videos in youtube... and I was totally amazed about yor research... greetings from Lima... congratulations...and thank you.

[@M1sc3]

Excelente trabalho, imagino a compexidade e trabalho gasto em cada um destes injetores.

[@captainemeritus5927]

Excellent!

[@schwabrs]

Please part 2, waiting for it and watching part 1. Regards dear sir .

[@typxxilps]

love it - thanks for sharing even though I had missed it before. A usual video would reach more I guess or a 2nd upload as a usual video.

[@FerdinandFake]

How did they possibly come up with a complex setup like that before any kind of simulation was available, or even any advanced fluid dynamics. It boggles the mind

[@truebsalgeblaese]

They broke down the complex system into smaller, more easy subassemblies

[@RocketPlanet]

Yes, and they tested, tested, tested... Then redefined the model based on test data, and then they tested, tested, and tested again. This rinse & repeat cycle ran continuously until almost the war's end. But as successful as the method was - and it racked up an extraordinary table of achievements - it failed to deliver anything close to what we would now consider an optimised engine cycle.

Billions of marks went into the development of the v2.

Please make the 2nd part of the v2 turbopump .

[@gregorydahl]

The mixing pot was mounted to the inside top wall of the double walled combustion chamber . The double walls carried the hot fuel up from the combustion chambers double wall chamber and were inches apart with the bottom row of swirl nozzles around the pot in between the combustion chamber roof and the upper outside wallthat the cover attached to . Itd be nice to press the whole thing out of steel because the chamber itself is steel and seems to hold up ok

[@chrisjones8791]

Wow the time it took to machine that must've been crazy back then

[@chrismofer]

Nice! Let's build one!

[@Eager44]

Nice

[@Xziriz]

Is this model available anywhere? would like to 3dprint it.

[@varunahlawat9013]

Why put so much efforts on atomizing just the Lox, but almost nothing for the fuel? (If I understood it correctly then the fuel will only be injected from the holes in the bigger circumference?)

[@Btolbert]

What software did you use to make this model?

[@donadriano3966]

Hi! Perhaps you can help me. I have some fuel injectors found at Dora Mittelbau, they have some interesting markings on them. HAP23 I already know what HAP11 is, but I can't find the 23rd one... I would be very grateful if you could help me figure it out! And maybe the photo of these injectors will be useful for your V2 rocket material base. I sent the same message, with a photo, to your "info" email Thank you very much in advance!

[@islandborn1457]

I never understood when people used to say German technology this German technology that Nowadays I catch myself saying "german technology" when I see the things they invented

[@simplex7096]

liquid oxygen? but didnt the v2 use hydrogen peroxyde or am i mistaken?

[@RocketPlanet]

Hi there. No, you're not wrong. But they used liquid oxygen (LOX) as the oxidiser for the engine. The H2O2 was employed to create a supply of high pressure super-heated steam (and some oxygen as a by product) to drive the turbine in the proplellent pumps, pushing the fuel and LOX into the engine for burning. Basically they used one rocket engine to boot-strap another! Thanks for posting. KR RJD A&NTV

great case of trypophobia

You cal that simple!?😅

[@evanj751]

So sad they put all this engineering into something that was made to be destroyed
