Bristol Hercules demonstration

Another demonstration of the very same Bristol Hercules engine as seen before on this channel. This was shot at the Borås airshow in Sweden this summer to the enthusiastic crowd's delight. Sort of an abrubt ending to the clip but nevertheless the sound is even better than in the previous clips so turn it up and enjoy!

[@johncarder819]

He's putting a lot of faith in those wheel chocks. Wonderful video.

[@pottsmic]

I was thinking the same thing!

[@johanneswarn5488]

The propellers on these kind of "show" setups are pretty much just for show and don't produce anything near the propulsion of the real propeller. Had it been the real propeller that was used on the Hercules, that little trailer would have taken off like a rocket when he revved it up and probably slice&dice everything in its path

[@Rositbuick]

*****

[@GGigabiteM]

Jonka Olofsson You couldn't put a full length propeller on that trailer without the propellers striking the ground. That club propeller looks to be 6-7' in diameter and is just a few inches from the ground. A full propeller would be 12-14' in diameter.

[@keithc9146]

GGigabiteM Probably helps keep the engine from overheating also.

[@Miskin432]

Perfect for keeping your PC from overheating minus the loudness.

[@thesayxx]

It comes standard on AMD graphic cards

[@99domini99]

Where can I get one, my Athlon gets quite hot in summer.

[@andynixon2820]

That's the most ' bloke ' thing I've ever seen . That fella doesn't waste time in the morning moisturising , just goes straight out to the shed and fires up his radial engine . I salute you sir .

[@tiagopadua]

The sound is beautiful. Imagine 4 of these running full power for a take off. I wish one day I can see/hear that in person =)

[@TheKGStarbuck]

imagine that flying over you with expedited boom delivery.

[@exothermal.sprocket]

This might suffice until then. kzbin.info/www/bejne/jpLOfGtnmsl-fKM

[@wipout1]

It was only after burning 200 litres to start it, that Bert finally realised that a regular 240 volt fan was suffice for cooling his garage.

[@OlympusHeavyCavalry]

LMFAO :-)

[@russellnc]

you win the internet today....:)

[@snoopytheace4487]

But it's so much more fun this way.

[@97GoldDust]

I have one of these inside my house. Great fan.

[@RJ-ue3ub]

yea a bit loud but whatever. cools just fine

[@brockolsen3689]

I guess, except for the fireballs and oil they like to shoot out the exhaust

[@vipertwenty249]

By far the best video of this kind out there. During the war my stepfather sat between two of these as navigator on Wellington bombers with nothing but the thickness of the fabric airframe covering between him and them.

[@Pholiage]

I bet the guy behind the engine was picturing Anakin going "It's working, it's working!!!"

[@invink6716]

Pholiage lol

[@Thewilddthing]

GOOD SHOW! BY FAR the best running, best looking, best sounding, & best operated test stand radial engine rig! Man you got it down smooth with that startup - warmup - runup!

[@OlympusHeavyCavalry]

One of the smartest operators I've seen so far, he's wearing ear protection. :)

[@afisherchessell]

I have attended this demonstration it is in Alberta Canada. The trailer is staked to the ground and there are legs at the front near the chocks The prop is a cut down version and has at least 12 to 14" of ground clearance. The crowd is about 20 feet back from the engine. You can't see the fire truck, fire men in bunker gear etc off to the left. Certified prop for demo, inspected and x rayed for cracks etc.

[@9102jack]

some people think canadians really are dumb enough to fire up a wwII giant aircraft engine on an unsafe trailer... you'll only find that at camp, not a public demo haha

[@ruthnorman1922]

Andrew Fisher-Chessell sure. But with all that said still a LOT of room for something to go wrong. All that precaution and the people are standing 20’ from the prop.

[@hughc023]

What a fabulous sound . . .

[@CraigBak]

I remember when I was learning to work on jets with one and two engines, across the flight line were about a dozen C-130 engines setup like this but on big A-frames and they were fantastic when they were cranked up!

[@mickkennedy1344]

I hope you eventually caught whoever stole the rest of your aeroplane.

[@510Redneck]

Mick Kennedy Being near salt water is tough on the ol girls.

[@roswalt1]

I was amazed at how long the spectators stood behind it as the wind and debris picked up. Very nice video and thanks for sharing this wonderful engine with us.

[@filipbitala2624]

Now just imagine it with a real propeller

[@robertoswalt319]

I have been around an AT6 when it was starting up and then taking off. I would imagine that the engine in this video would dwarf the one in the AT 6.@@filipbitala2624

[@Totally_B]

I thought the world was going to end. EPIC display of engineering and marvel. Brilliant!!

[@k.c.lejeune6613]

Cleared out that lot behind the engine and operator, that is one monster of an engine. Sound is incredible!

[@Matto216]

Some people will never be happy with a normal leaf blower haha.

[@chrisbroesky2932]

Sounds better than any Harley.

[@imnota]

Most engines sound better than a harley

[@user-jn2kz9jg7l]

😂

[@dvddmc]

this vid is still fun to watch after all this time Loving hearing this thing Rev Up

[@dar5204]

Very cool I love the look and sound of these old engines

[@MrPants1970]

Wish the video went on until the end, sounded amazing!!!!

[@pjotrslanina1403]

Yes, me to!! Indeed very amazing!!

[@1966Hemi426]

That looks about as safe as my wife's cooking.

[@ntchpt1271]

if she reads this, she'll probably feed you to the hercules. that took guts!

[@skagit69er]

Her cooking can't be too bad if you're still alive !

[@510Redneck]

1966Hemi426 Yeah, its pretty bad when one opts for "pink slime" over their wife's cooking also... bahaha

[@BobbyTucker]

What's it worth for me to keep my mouth shut? lol. My reply is only 2 years late. lol.

[@willyhearrell9060]

+Bobby Tucker hey im only 4 hours away from yours? Lets revive this puppy.

[@atc200xfanatic3]

That thing sounds like a beast! The wind had to be unbelievable behind it to clear out that lot. Serious power here. Great engine.

[@pjotrslanina1403]

Whát a SOUND!!! PERFEKT!!! One of the most beautifull engine-sounds I ever heard.

[@GeorgeBonez]

First thought! The general public will trust and stand way to close to things they don't understand! The operator: Safest seat in the house! haha

[@GeorgeBonez]

+GeorgeBonez Fuck I just read the comments of others and I see that I am not alone in my thinking. Damn that made me feel good because I usually am! haha

[@swagrider4243]

WATZ DA FUCK

[@versianimoreira]

Very dangerous!

[@brokenbeforetime]

I think they are relatively safe as long as they don't fall into it.

[@GarageNation353]

The blade is running at neutral pitch so there is very little thrust..but still relying on 60-70 year old components and a very heavy reciprocating mass.... I'd be standing behind it.

[@JOURNALISTICREVIEW]

I use two of these to cool my cpu. They work wonders

[@Bastacat]

Don't worry,i bet his house is moved a lot.

[@exothermal.sprocket]

Keeping that processor chilled when you're overclocking the system on that mean video game.

[@brian5o]

That engine is a work of art.

[@WornGlobe]

The amount of air that’s shifting is incredible.

[@NGH99999]

Dear God, this is pure machine porn. I can't stop watching this. That idle is killer.

[@fluffycheep]

Designed my man. A purely brilliant thing. We need to control our own minds too. It will give us a more controlled insight. Love this video

[@BHillerCartoons]

this is just sheer power. love it

[@kevinbourgeois9310]

It's amazing how they put aluminum and steel together and made beautiful music

[@rolfen]

Beautiful sound I was thinking, though, I can imagine this thing ripping itself free, shredding through people and going airborne if only the throttle is pushed.

[@DerGizmoKanal]

+rolfen I like your thinking :)

[@alexandrinagolveia3645]

Uy4wt

[@bfmcarparts]

This video is a great example of peak engine performance in certain rpm ranges. Can you imagine a camshaft profile designed with the idea of smooth running at a certain rpm range yet just be within reach of allowing it to start with massive changes in ignition timing? Another example would be to compare the starting of a regular production automobile that idles smooth and drives well but loses acceleration at high speed. Then compare it to a drag race car that idles so raggedly yet when at high rpm it is able to keep generating more power, until it runs out of track. This is a great video that displays this idea well, its a shame we don't see the operator bringing the rpm down to shutdown.

[@kimchipig]

There are no camshafts installed in this engine. It uses sleeve valves.

[@bfmcarparts]

Len Peters You're quite right, I wish there were more of these sleeve valve motors around but the technology just didn't catch on. Even the few Sea Furies flying now are losing their Centaurus engines. My example was also based on something well understood, the camshaft-controlled auto V8. Thanks for pointing out my error.

[@larrydepretis2281]

I love the lumpy sound of the camshaft "cam ring" idling and as it came up in rpm's

[@larrydepretis2281]

I agree!

[@princesslithium]

Love the sound. Like a powerful heart bit.

[@Klaudyors]

Maravilhoso ver uma máquina destas funcionando!!!

[@Peizxcv]

I can see so much use in a zombie apocalypse. The blades provide chopping and forward motion.

[@jpatt1000]

+Peichen01 No, the blades need to be horizontal like a lawn mower for maximum decapitation action!

[@rodneyhendricksonhendricks8423]

Man I'd Love to see this up closer ! Very Nice Motor

[@6Twisted]

Beautiful engineering

[@milanhlavco3631]

after 3:15 best engine sound ever

[@electronicshelpcare]

wow, what's a video. at first, I thought that it will be fly away.

[@gordotiti]

A thing of beauty.

[@gh0stmast3r]

yeah that looks perfectly AWESOME!

[@DIOSpeedDemon]

THESE R.C. ENGINES ARE GETTING QUITE LARGE !! WHAT kind of model RC plane does it fit into !!!... 5 STARS***** RH DSD

[@YoloToTheMax104]

I don't understand why everyone thinks that there isn't a single safety precaution in sight. If it weren't safe, then it wouldn't be at that field to begin with

[@tomasinacovell4293]

I very much doubt it.

[@tomasinacovell4293]

***** That's right, and just for starters, heh... But the whole affair is all a bit too up close and cheeky.

[@mikebreen2890]

Nothing like this can ever be "safe", not as some expect at least. It can only be a reasonable risk.

[@user-bi4wj4kv3u]

💪❤💙💋👄💞💔

[@Flies2FLL]

Awesome that he brought it up to power like that!

[@BellerGarage]

i will need one of these for summer

[@GeorgeRadu95]

This would make an awesome cooler for my pc :3

[@gammaraider]

He had hair until he started this engine

[@510Redneck]

gammaraider I had hair until I watched this, I want a refund.

[@pugetsoundbusinessexperts8903]

I love these old radials. Hats off to the video guy who ran us through the initial start and warm up. Cachug cachug... Vroom!!!!! Yeah

[@areubaked]

I keep coming back again and again to watch this video. Especially the last minute of it. Those stakes next to the wheel chocks must be driven way deep into the dirt! Note to Santa: Please?

[@WhiteNacho]

Bummer I thought he was going to drive it.

[@GooglFascists]

Where's the rest of the plane?

[@santervaz]

Thanks a lot for the video. Really awesome

[@artgoat]

The Bristol Hercules was a 14 cylinder, 2-row radial engine available in ranges from 1290 HP to 1735 HP. The Hercules I had a bore of 5.75" and a stroke of 6.5" for a displacement of 2,360 cu in. It weighs just under a ton, without propeller. It runs optimally at 2,800 RPM.

[@matk22]

fuck standing next to that spining blade so close

[@SONOFAZOMBIE2025]

even if you were 50 meters away, if the prop comes off it will cut your ass and face in half.

[@Polioooo0]

Son of a Zombie Even at 120 meters it can still cause very heavy damage. Depending on the blades but still, fuck..

[@4570Govt]

As cool as this whole contraption is, I'd have thought that they would have allowed for a tad more ground clearance between the bottom of the props rotation pathway, and the ground. I'll bet it's rotating(at rather high speed, too, mind you) at less than 6" from the dirt... I'd feel much safer if it were in the 12-24" range. Taller, yes, but much less chance of sucking up errant debris from the immediate vicinity

[@hipstarchild]

Incredible engineering !

[@vadvetjag12345]

Thank you!! love your video most be wonderful to stand behind that kind of powerful engine...

[@marklowe7431]

Amazing engineering considering there was no cad or cnc machines, engineers back then were genius

[@JohnSmith-pd1fz]

+Mark Lowe Barnes Wallis and Nevil Shute Norway era. Genius in every sense of the word.

[@vector6977]

Hand drawn blueprints need to be hung up as works of art too!

[@aurelienclair4465]

yes. now we can't do it without computer.

[@dekemmeterjacques-etienne8505]

14 cyl, 38.7 litres, 1675 hp

[@leneanderthalien]

The last built Hercules, a improved version "739" 2040hp was made by SNECMA in France up to 1964 to fit the Nord 2501 Noratlas

[@kamikazeratte]

Love this sound!

[@AnjayKm]

The second half of this video gave me goosebumps !

[@kpadmirer]

Whispering death.

[@Skracken]

Sleeve valved engine?

[@pottberga]

Japp!

[@vet6822]

Niklas Bergsten correct. it is.

[@Flies2FLL]

+Niklas Bergsten Yes, sleeves. They use castor oil as a lubricant.

[@josephgoodman6506]

+Flies2FLL Ahhhhhhhhhhh the smell of castor oil from an exhaust, never forgotten. As a kid 50 years ago in the UK I used to run motorbikes on Castrol R just for the smell. :-) Or just put an egg cup full in the petrol tank on every fill up on bikes that wouldn't cope with the R as a lubricant.

[@vet6822]

+Niklas Bergsten google it.

[@digitalbroadcaster]

Reminds me of watching one of those classic war films with that superb purr of the engine from a bomber. I'm in love with an engine! Shame the video finished. I wanted more.

[@cjack56]

I need a fan like that- it was 102 degrees here the other day... Seriously: Beautiful engine! Nice restore job.

[@progx8679]

I'm Amazed it didn't pull the trailer ! : )

[@bretmuldner]

He must have some sort of a lock out on the hydro valve for prop to keep it from adjusting too far other wise it would!

[@yordanvazquez7582]

the trailer I locked in place or else bye bye

[@siggivanutrecht]

The wheels of the Trailer were locked. If not.... have a good flight and when the lock lose.... you can see a crowd of people without heads or you have enough meat for meatballs...... horrible thinking.....

[@sc0tte1-416]

I wonder who had the smart idea to set it up right in front of all the loose dirt lol

[@petericyou856]

Awesome goes right through the bones love it....

[@pjotrslanina1403]

What an insane good video!! I hate it isn't longer, because that sound....It's music to my ears!!

[@JacobTJ1]

tat setup does not look safe... disaster waiting to happen... i understand the trimmed prop but still..

[@mikaelabowen5781]

Lovely sound!

[@henrikmartikainen8472]

The best ever engine sounds.

[@TheOfficialArcVortex]

who needs a hair dryer when you have this guy and his engine

[@timhorton7399]

Wow, what a monster! Sounds great...I don't know why anyone would hate the power of this engine demonstration...maybe a little loud but the sound is meaty.

[@richmerne4269]

This is the most terrifying captive thing I've ever seen - emphasise that it's captive - mind boggles at how the trailer is nailed down to stay there - and if it didnt !!!!!

[@stanhathcoat920]

Great engine! Notice even the shortened prop wash cleared out the crowd in the rear for 50 yds.:)

[@kapnk066]

Kudos' to those standing to the side in perfect alignment with the 4 blade projectiles that are under massive stresses trying to separate themselves from the center hub.

[@ThomasDoubting5]

They are there by assuming and by a lack of knowledge even though all of them at some point would have Been swung around by their arms in play.

[@winchuni22]

That is an absolute monster!

[@USMC_BABE38]

One of my favorites

[@motokill35]

Best one i have heard to Date

[@TheBonafideHustler1]

super awesome!

[@breeze901]

Never seizes to amaze me :o

[@MavAuto-Pete]

Look at the power this thing has it certainly cleard a space behind it.

[@dvddmc]

This Vid Freakin Rocks! I love the sound when he revs that motor up. People don't have to stand there if they didn't want too. I would be right where this guy was Awesome! And I love how the people behind it Scattered

[@heathfiedler]

got to love the sound with he power its to full

[@63256325N]

What a sweet sound....

[@knobsdialsandbuttons]

What a beast ! 👍

[@Demenis007]

beautiful rly beautiful i love this engine its simply magnificent

[@conorhynes462]

Literally goosebumps every time I watch especially when he’s give er the full pipe 💪🏻

[@justforever96]

there's something so friggin cool about giant piston engines!

[@richmerne3593]

Such a thing of raw twentieth century genius - I'd certainly have it installed on my ride-on mower - no more grass, no more mower, no more me.

[@robbynelson3]

Every man needs one of these to tinker on in his garage!

[@TexasRushing]

Man I love the sound of a big radial engine. There is someone who hangers a plane at our local airport that is powered by the Pratt & Whitney R-4360 Wasp radial engines. You can always tell when he fires it up without even hearing it, just have to watch for the huge plum of smoke. Harleys don't have anything on these engines when it comes to sound.

[@lawxxxx9853]

Magnificent!

[@xxxchrist1]

Fantastic!!

[@MartinQuinlan1]

Perfect for an air boat project

[@spmspeeder]

Display of total horsepower. Fantastic.
