Bristol Hercules demonstration

[@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.

[@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 .

[@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.

[@larrydepretis2281]

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

[@larrydepretis2281]

I agree!

[@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

[@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.

[@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.

[@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.

[@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

[@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!

[@Pholiage]

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

[@invink6716]

Pholiage lol

[@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.

[@OlympusHeavyCavalry]

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

[@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

[@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.

[@RalphEllis]

Thought it was going to tip over at that power setting. What was holding it down?

[@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.

[@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.

[@Totally_B]

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

[@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.

[@FiveCentsPlease]

The prop blades are cut short and they aren't throttling up high enough to overcome the weight of the engine and trailer. (They can't because the short prop blades won't put a full load on the engine and it could over-speed and be damaged.) However, having the crowd so near the rotating mass is cause for concern if the engine happens to throw a piston or other parts.

[@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!

[@diecybenmtb]

Wonder how quick you could get that trailer going down the motorway.

[@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.

[@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.

[@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

[@coroboree]

The prop always turns in the direction to blow air back (to the left in the frame) to propel the plane, when attached forward.attached

[@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.

[@macswad]

I line in the UK - is there anyway I could see one of these engines running on a trailer as depicted in this video? I have some guests flying in from USA & Canada.

[@MrPantss]

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

[@pjotrslanina1403]

Yes, me to!! Indeed very amazing!!

[@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.

[@nichvaffe]

I wish so much to hear the full speed. Why was it cut off?

[@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!

[@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

[@chrisbroesky2932]

Sounds better than any Harley.

[@imnota]

Most engines sound better than a harley

[@frankenstein-r7g]

😂

[@trmast01]

Harley Davidson lives rent free in all of your minds😂

[@vilasalazar]

holy shit! what aircraft was this monster fitted in? surprised it doesn't pull the trailer away

[@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.

[@stanhathcoat920]

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

[@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.

[@سلطانسلطان-س6ز]

💪❤💙💋👄💞💔

[@ZenTauren]

If i give it more gas, can i ride this thing to work?

[@mannequinfukr]

give it some steering thing and you might

[@510Redneck]

***** Would certainly give a new definition to social hacking id imagine....

[@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

[@6974]

i heard sleeve valves are quiet. this seems real quiet considering how much air it's moving.

[@NGH99999]

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

[@rcdieselrc]

Does anyone know if there is a running Bristol Hercules in the US? I'd love to hear one in person.

[@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.

[@Newbpwng]

im guessing it needs to warm up before it starts running in the proper timing ?

[@electronicshelpcare]

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

[@CiboloHemi]

Do you not see the Propeller inches from the ground? It would take less than you think for it to strike the ground..

[@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.

[@relentlessmotion]

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

[@wicqedeyebot5631]

Lucky thing I wasn't there. Anyone help me get a link on how this engine work.

[@DIOSpeedDemon]

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

[@The707200]

yes many engines are sleeved....the heads like modern cars are sleeved, aluminum heads in both case, and steel sleeves or carbon like material (Honda as I recall), valves are in the each design as well...intake and exhaust

[@milanhlavco3631]

after 3:15 best engine sound ever

[@steverush4402]

Note the stakes and chocks in front of the wheels. There might also be a stake through the trailer tongue.

[@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.....

[@andyharman3022]

He seemed to be taking his time when the engine first fired up and was only running on some of the cylinders. Maybe he was waiting for it to warm up some? But when he got all the cylinders firing, it was beautiful! I love hearing a big sleeve valve engine run.

[@JacobTJ1]

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

[@michaelhartzell9758]

Ive seen this video before but never noticed the people leaving from the back before. Great view but the wind and dirts alittle strong. Pretty nice

[@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

[@SyedRiyadhulKarim]

you are right. but i mean its extreme centrifugal force and velocity , weight balance and forward thrust. something could be enter in its rotation that can cause fire.

[@WhiteNacho]

Bummer I thought he was going to drive it.

[@Draxindustries1]

This is how a radial should be run, with the exhaust collector ring in place. Theres so many run without them and they sound rough as a badgers arse without..

[@Klaudyors]

Maravilhoso ver uma máquina destas funcionando!!!

[@WornGlobe]

The amount of air that’s shifting is incredible.

[@sc0tte1-416]

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

[@jzzr345]

I've always liked this engine . They built quite a few in WW2 . I wonder where they all went ? There must be some still lying around in crates somewhere in England .

[@TheDaz167]

thats an expensive fan

[@MrTespro]

Who made the propellers? They look like the ones made by the Aeroproducts Div of GM.

[@GeorgeRadu95]

This would make an awesome cooler for my pc :3

[@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

[@Kennynva]

how does the starting system work...I can hear a sound of a servo, or air starter??? and can you restart it in the air if it fails,??

[@gammaraider]

He had hair until he started this engine

[@510Redneck]

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

[@kevinbourgeois9310]

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

[@kpadmirer]

Whispering death.

[@applicareinc]

The people standing (beside the blade) there remind me of those in NYC who walk across the street against the traffic light without looking. I ask myself, What are they thinking? Is the term Knuckle Head still used?

[@Paxmax]

Temp outside 14 deg C... with wind chill factor in prop wash -8 deg C.

[@cjack56]

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

[@flatlineheartbeat1851]

What keeps this engine from pulling the trailer forward?Is it because the props are not angled right for it to pull?

[@ChristianMcAngus]

Compared to an 18 cylinder P&W radial it really is a lot quieter - I guess sleeve valves do make a difference.

[@jorgelovescoffee]

damn how many torque does this engine produce at full tilt

[@jonmpb578]

🙃 I've a VW bettle that needs an engine... where can I get one...?

[@dar5204]

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

[@xsavierneogeo1569]

at the end ,,,, is it just idleing ???

[@NickRatnieks]

That's fantastic! If you can find three more and a Short Stirling to go with them, you'll be away!

[@nocod100]

Mr crew chief I have a question... can you tell if the prop was feathered ????

[@kenhanson4015]

How fast can the trailer go if they unchok the wheels?

[@Jackfrost751]

how is it not propelling the trailer its sitting on?

[@WingNuts2010]

I have an old go-cart in the shed and I want one of these to go on the front. Would it be street legal?

[@punman5392]

Is it just me or do the prop blades seem short?

[@JohnSmith-pd1fz]

+Matt Bowen Very short compared to those used on the aircraft itself, the Bristol Freighter which stood as high as a three story house. However there has to be a minimum 'load' on the engine in order to be able to run it safely, hence the specially made prop seen here.

[@GuzziHeroV50]

Also: a demonstration of the propulsive power... as demonstrated by the crowd behind moving away!

[@TheDawg475]

can someone plz tell me why the propel seems to start spinning the other way at this point 2:35

[@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.

[@Peorhum]

The McKenna brothers made a big deal about the Halifax having a blue flame coming from the engines, giving away their positions at night. I really can't find much to confirm this. The Merlins were in many planes so if the Merlin equiped Halifax had the issue so did the lanc and mosquito. If it was the Hercules engine I can't find anything to support that either. Can anyone confirm this or is it just a little bull the McKenna brothers added to their documentary to get some reaction as they commonly do?

[@MissKay1994]

Why is the sound of radial engines so addicting?

[@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.

[@nerd1000ify]

It develops around 1700 horsepower. the Propeller, however, is a test prop that produces relatively little thrust. I would be more worried about the people standing behind it, these things run on fuel with truckloads of tetraethyl lead in it.

[@Flies2FLL]

Awesome that he brought it up to power like that!

[@MarttiSuomivuori]

Sounds so much smoother thatn the American radials. It must have been one hell of a lot more expensive to make?

[@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.
