Svarthalet Racing - Testing the new pulsejet engine

Testing our pulse-jet powered snowmobile prior to Speed Weekend on Ice in Orsa 15-16 February 2013.
With the new engine we increased the thrust to 1700N (~380lbs) witch is ~600N (135lbs) more than last year's race.

A noise complaint from 7km away. That is excellent!

[@sillenHDsportster]

+Kauwhaka Last year i heard it over 12km away ! :-)

[@nightrous3026]

Dayum. That is impressive. Honestly i wouldnt even be mad. I would be impressed.

[@andyharpist2938]

increased after tuning to 8.23km

[@supertyfon1736]

It might be heard 50+km away over the ocean maybe.

[@androidemulator6952]

7km away .. pffft. Lets try for 14km instead! ;)

G'day, Come to Australia mate. It's January 2020 & we're perfecting MUCH bigger fires than that one. Global Warming mate. December 2019 was 1.98 degrees Celsius hotter here than was December 2018 ; and December 2018 was 3 degrees Celsius hotter than was December 2007. Global Warming is WINNING. Due to The likes of You... You selfish reckless irresponsible Fossilburning Planet Wreckers. What the fuck do you think you're doing THAT stupid decadent SHIT for ; becsuse you're otherwise bored with your meaningless excuses for lives, one supposes ? There's a Backyard BLEVE (Boiling Liquid Expanding Vapour Explosion...) with your Social Security Number on it, lurking up ahead of you-alls, within your Karmic Pipelines..., unless y'z change your tracks, entirely....!

[@ohwell2790]

A friend and I many years ago now bought a little 4 pound thrust pulse jet. My friend and I where home on leave USAF. We ran it on the drive way bolted to a six by six timber. We got it running and set the asphalt drive way on fire. My dad came out the door with his high ball ( burbon and water) in hand and said. When the fire department shows up I'll tell them you two do not live here you are just passing thru. How cool is a dad like that, he passed away and we always had a good laugh about that. Miss his humor a lot.

[@LaRdArms]

That is a great memory.

You just started an iron-age pod racer.

[@Andy-qo6rq]

Omg my Nan used to say how bad the noise was in the blitz when the flying bombs came over from France during the Second World War. The thrust on that is amazing. It’s on my Christmas list.

[@ONEFUNFONE]

Well that's one way to keep you're balls warm in the winter time!

[@indridcold8433]

Some people of advanced age may find the sound it makes quite familiar in England. The siren and the pulsejet will stimulate some old memories in them.

And you might be interested to know that we use both earplugs and earmuffs. Yes, this thing is quite loud....

[@kalleklp7291]

Almost 400 Lbs of thrust...not bad guys..! Cool project. Currently working on "the resonator" , think i will be around 600 Lbs of thrust on kerosene. Startup on butane, double fuelpump for the kerosene..hell..might even run on diesel/gasoline mix..

[@leifvejby8023]

[@chrisellertson3352]

I had a party like that once, five miles away people heard the music clearly. We had an amazing time. May Long Melt 2005. Cool design, I however would add another chain just in case. They are probably just using what they have which turns into property damage, I know I grew up on a farm. Great work guys! your racers, your using your rational brain.s......right??!!!!!! lol

[@anywaystohighway]

I wish there was a 3 hour loop of the engine running, I like to put this on as white noise when I go sleep, it really relaxes me from all the annoying noises from the house

[@Andres131995]

but extremely simple, almost no maintenance, runs on almost every flammable liquid or gas, and WAY cheaper than a turbine engine.

[@haraldlindohf4032]

I think that I just fell in love with this video

I love how the camera falls over at 5:05 That thing is amazing, cut the chain off while its running XD

[@comicsans6330]

wow thats awesome! id get one just for the shear noise it would make . .. ripping across a field being heard for miles . . would sound like an old bomber jet for someone who didn't know better

[@stevek5416]

So, you had to apply a little choke to get it to run properly (block off some of the reed valve)!

[@cyleleghorn246]

oh there's compression, over 100 atmospheres in a normal pulse jet, probably way more in something like this

[@brettmclauglin8574]

Pulsejets are pretty sick, same type of engine that was used on the V-1 buzzbombs in WWII by the Germans. Very simple, very effective engines--they guzzle fuel and make a terrible uproar though (obviously)

[@thedeadlinger6992]

I've just discovered that a Rocket Motor doesn't make that much noise as much as a Pulsejet Engine/Jet Engine. Or is that just.. vice versa?

[@ottanicubano88]

[@frank4579]

little bit expensive just to get the roads clear of snow, but quite effective.

[@ardrie]

wow even more impressive than Maddox

[@joeeveryman2208]

This reminds me of work I did in the '80s with open megaphone racing exhausts, you are in effect controlling a harmonic pulse like a church organ pipe. How did you arrive at the tailpipe length? The reason I ask is it looks as though the pipe is a little short, especially if the flair cone had such an effect in the way it did.

[@jackoghost]

you guys are nuts... i'm loving this :p

[@lomasck]

What is the tail pipe in mm.My er90 RC gets 16lbs with a 55mm tail pipe.You can work out what you could get from this.

[@jonidimo]

What happend if you put an inverted conical extension? I mean ... the end part smaller. Just a question.

[@fahadislam1849]

The engine would just set fire to the fuel without producing any noticeable thrust like at the beginning of the video when the pulse jet wasn't starting properly and created a lot of soot. This is because pulse jets rely on the fast moving exhaust gases to create a pressure drop in the combustion chamber so that hot exhaust gases are automatically fed back into the combustion chamber to ignite the next batch of fuel. So a pulse jet engine has 4 cycles: suck, bang, blow, exhaust suck back. If you add an inverted conical extension, the pressure inside the combustion cylinder will be higher than the pressure outside the cylinder so the exhaust gases won't get sucked back into the engine as low pressure does not move to high pressure and then the engine will be missing one of its 4 cycles to function properly. An easy way to remember this is, fast moving fluid=low pressure fluid and slow moving fluid=high pressure fluid.

[@mdsysltd5573]

that thing packed some power.

[@thevinstigator2511]

*Regular Gasoline Engine* Bad to have backfire *Pulse-jet Engine* Hold my bear

[@rwbnatureadventure3876]

So cool, how does this compare to the thrust of a v1 rocket?

[@hoodoo2001]

V-1 was 660 pounds and could push a one ton warhead at over 400 mph. Could not accelerate to the necessary 175mph for launch though.

[@Sam-ob4of]

​@@hoodoo2001 you mean 299,37kg; it could push a 1 ton warhhead to 281,64km/h

[@skumanders]

Om intaget är riktat åt rakt motsatt håll mot avgasröret, borde inte då kraften framåt och kraften bakåt ta ut varandra? Upplys mig.

[@skumanders]

simpelt och smart, tack

[@ollymetcalfe1]

Its strange that the exhaust gases seem to point down slightly rather than going straight out the back. Anyone know why?

[@Marco-nx5tj]

Gravity lol

[@LaRdArms]

+Olly Metcalfe Its because gases traveling at high speed have a lower pressure, so the exhaust gases are "pressed" down by the surrounding air.

[@eddesroches4337]

Boyle's law.

[@scottydouglass1892]

How many mullets were in that crowd?

[@Videoboat2008]

OMG!! Take a look at the camera shake.. I get that kind of shake from my camera mounted directly on the aircraft.. That cam is a good distance away and the percussion waves are shaking the hell out of it.. I would hate to be standing next to that thing.. Ear pads or not,, there's some bodily harm going on there..

[@yeet4924]

it's like a giant flamethrower...a ramjet can produce much more thrust in more concentrated beams of energy... with that being said you should try a ramjet instead, or if you are top of the like type of guy a turbo ramjet should be your fit. this means it'll just have bypass tubes sitting over the multistage diffuser and carrying air that entered the necel all be way to where the thrust exits the afterburners, an just optimizing maximum thrust capabilities.

[@ohwell2790]

Like anything that makes noise and fire.

[@johnjenin8077]

From many videos about pulsr jet I've watced all the flames that comes out from the nozzle is straight but this one the flames is going down how that happen.

[@LaRdArms]

The high-speed (and low pressure) exhaust gasses are surrounded by the (higher) atmospheric pressure on only 3 sides, so it's forced downwards by the atmospheric pressure I belive the reason it's more noticeable on this engine is that it's quite large and its mounted relatively close to the ground.
