Steam Engine 9 cyl Radial

[iNatevlogs]

Cool!

[surinderdhiman]

Awesome! Definitely could become a useful source of less expensive power in the coming time of oil crisis.

[808ROTY09]

wouldnt the steam blind the pilot lmao

[thercpoop]

does the setam lube up the engine too?

[Fred196407]

Now that is sweet. I had Mamods back in my younger years but that beats them. Thanks!

[Verradonairun]

@av8navig8 What fuel did you use for heating the boiler?

[superbungabunga]

perfect for the zombie Apocalypse, cant always really on gasoline and this is cheaper and can be made of wood or plastic

[SergioDoenetz]

Красиво, но не полетит. может пропеллер раза в четыре крупнее, да давление побольше?

[mikekevin90]

now that's steampunk :P

[kenp3L]

It doesn't look like it's using the steam very efficiently. Also, with airplanes, keeping the weight down is key. This think would need to haul around a big heavy boiler and fuel. Maybe an aircraft with such an engine might get off the ground, but I doubt that it would travel far.

[DAKOTA56777]

@kenp3L Well the Belser steam plane few it used a "light" boiler, a compound steam engine (Steam goes from the main cylinder to a low pressure cylinder to be used again.) and a condenser to condense the steam back to water and fed back to the boiler to be used again. A normal simple expansion steam engine is under 10% efficiency but a compound adds 10% more and a super heated boiler another 15% to make about a 30%-35% engine efficiency steam engine. About the same as your car.

[kenp3L]

@DAKOTA56777 I'm skeptical about your figures. If your getting 10% of the available energy with the high temp steam on the first go-round, then using the same process with lower-quality steam would only extract the same proportion of the remaining available energy, which would necessarily be less than 10% of original amount. Could you please cite the source of your efficiency figures?

[kenp3L]

@kenp3L Oops! Should have written, "If you're getting..."

[DAKOTA56777]

@kenp3L I just remembered that it does get 10%, because with the superheating the HP cylinder is getting about 15-18% so the LP does add the 10%.

[partsproduction]

I would not expect to see cooling fins on steam engine cylinders, that's a lot of work to go to to make the engine LESS efficient.

[Wodenhelm]

Heh nice, where can one of these be bought?

[cow1324able]

dude thts bad ass

[brestingheedness]

Hey why do the cylinders seem to have heat dissipators?

Like those of gasoline internal combustion?

[SMGJohn]

@vodafoneoff Fuck off pest

[soso75233]

O-o



[ardnaxelanz]

That is very cool indeed! Nice work!

[sspark67]

이 제품 구매 할 있나요?

[caze]

I dont think we cannot made that engine to fly something hehehe

[TheRevo33]

please give instructions for this i would love to make one please please please!!!

[porpoisefathom]

how did it manage the wieght of the feedwater??

[JohnMC894]

Very well done. An interesting video. I do seem to remember reading about the use of a radial steam enging in aeronautical use has commented on before.

[XxnegociatorxX]

I like how you used the radial crank to operate some "twist" valves instead of an over complex set of OHV's like some of the other designs on the web.

[CablloBlanco]

Awesome

[Cam5X5]

omfg I so want to make one of these! except with the tools I have I would have to settle for a cruddy wooden one :/ Oh well that would still be fun to do!

[ReisendeEuropa]

@Cam5X5 Make one of wood.. I'd approve of that. Not quite sure how you would seal the wood itself to keep it from expanding when it got wet.. perhaps wax or something? DO IT!!! :)

[HybridWaterMan2]

What a beautiful piece of engineering - nice job.

[agpilotphil]

That thing is awesome. I need one to put in my kids' toy airplane I built them.

[BenZeneProject]

gorgeous. simply gorgeous.

[1939PlymouthRatRod]

1933 was the first steam powered flight 10 gallons of water to fly 400klms

[MORK455]

Well, that is a thing of beauty!

[joedrummer2010]

THAT'S WHAT I CALL A WORK OF ART!!!!!!

[KenMacMillan]

Next you need a Lamont boiler & a bicycle to mount it on! lol

Seriously though, if you plan on flying it I would recommend a Lamont boiler. It's the lightest & most powerful steam generator for all practical purposes, even better than the doble's. It would give you super heated, extremely dry steam & you could run it on any liquid fuel or even propane if you wanted.

[tiggeroush]

This is cool, I wish you had a video on how to make it.

[RubyRhod]

Sir? SIR! Your engine is burning!

[amazingguitarsam02]

Its amazing how quiet steam engines are, It is truel a wonderfu method of power

[joshuago8]

It look great does it have a propeller ?

[marcjtdc]

does this run off of steam?

[65pont]

I know virtually nothing about steam engines, but I could watch this thing run for hours...

[luc59457]

excellent video, I think some solar steam engines would perform well vs size.

[Polybun]

too bad the fins on the cylenders cost it effeciency. You don't want cooling fins on a steam cylender. You want that thing to get hot and stay hot.

[ilovetails123]

hey honey i made a new fan to help cool the house down :D

[WmCElliott]

The British built a steam-engine-powered bomber as a feasibility demo, just in case their oil/petrol supply lines were severed by the Nazis. It flew, according to all accounts, rather well, as decoupling the source heat (boiler) from the engine cycle allowed it to maintain higher altitude, and it used a simple duct intake to both cool the steam (closed-cycle) and "supercharge" the burner, which could run off coal or low-grade diesel oil for fuel. It could also gather water from the ram air.

[Daevo69]

@tokejyn noob...airplanes crash. Think of the fallout. Noob.

[engago16]

thats a great work of art keep up the good work

[gblpst81]

That's really nice. How long did it take to build? With sufficient steam pressure, could it run faster?

[BushPilot444]

How can you keep it lubricated with the steam washing out the oil and doesn't it cause it to rust while stopped?

[beautifulwuss]

Do you have any plans, blueprints, or drawings that you are willing to give out or sell?

[DAKOTA56777]

There ws a steam plane uh 1920s or maybe 30s I don't rember but anyway it flew it was the first practical steam driven plane. Not a radial but a compound with condenser for longer flight.

[av8navig8]

@DAKOTA56777 ,

I believe it was Besler Bros. ... Pretty amazing engineering for the time.

[TableWolfMusic]

@av8navig8 ...so, I'm guessing in principle, that if they were to have glided that steam plane backwards, through a cloud, the water vapour/cloud droplets would turn the propellers. Then coal would appear. ;p

[brey213]

all backwards.. real steam engine condenses the steam to water in the cylinder and is powered by the vacuum created .. cool model!

[DAKOTA56777]

@brey213 ...I'm not sure what you mean by "real steam engine" because all steam engines built I heard of are expansion engines to where the expanding steam pushes a piston, and the condenser on these engines take the hot steam and converts it back to water which is then fed back to the boiler and used in the engine again. Most common use for condensing steam engines were on ships and steam cars where fresh water is too rare to be wasted.

[DAKOTA56777]

@brey213 You might be thinking of the very first steam engines which were atmospheric engines.

[brey213]

The first steam engines where used to pump water out of deep mines. the piston drew the steam in on the down stroke and a squirt of cold water was injected, quickly condensing the steam and sucking the piston up.. could be an atmospheric engine i guess, but a flame licker motor is allright too

[wind4watts]

@DAKOTA56777 Yes amazing was it called the Besler Steam Plane (maybe)? it's here on you tube.

[thepilotseat]

@DAKOTA56777 You are right ! It's Bessler (Ithink I have the right name) & it's on YOUTUBE ! ! ! It flies forward, lands & backs up too! Amazing for short field TOL's ! I was a steam engineer on a Coast Guard cutter some yrs. ago & I LOVE STEAM ! ! !

[DAKOTA56777]

@thepilotseat I love steam too, steam engines are elegant pieces of engineering.

[sanddune1981]

where is the plane?

[speedstick77]

Consummate craftsmanship! Thank you for sharing!

[NonLinearFunction]

5 hp?

[skylinevspec000]

@jorgrannymonkey..

The soviets and the US tried atom fueled planes in the 60's they were looking at basically fueling it but atom fission. This would have been better. fission to create steam steam to power engine, condensors to reclaim water. etc etc. still limited range tho. water is heavy..

[gumby1008]

why the cooling fins, steam shouldnt require that much cooling

[MichaelJGrant]

While on an internal combustion engine you want finned cylinders and forced air for cooling, on a steam engine you don't to cool the cylinders. That results in condensation during expansion putting water, which is incompressible, in the cylinders. This would be particularly true with a radial engine which cannot relay of gravity to force any condensate to the drain port. Most steam engines use superheaters for efficiency and to avoid this problem. That aside, your engine is pretty nifty.

[lilbrudder32]

@MichaelJGrant but steam engines, unlike an ICE don't have a compression stroke, so when exactly would this engine be trying to compress condensed water from steam?

[DoNotuseEbid]

how much air would you need to run it for 10min? could it be used on an rc aeroplane?

[lilbrudder32]

@DoNotuseEbid It would be a pretty large RC plane, it seems. The engine appears to be nearly as wide as the doorway behind it in the video. Compressed air does not have as much storage potential as steam. You'd need a lot, I'm sure. He's said he's running it on a pressure cooker in this video, which doesn't provide much pressure or volume.

[valve0radio]

i imagine the cooling fins might need to be removed/ insulated to increase efficiency - and avoid condensation in the cylinders?

[Honker00]

Star engine, end?

[bobatosenior]

Interesting. Good job!

[xzharmayne03]

wooo its kinda ultra hot!

[dithbmine1]

impressed

[rayunseitig]

That's amazing! good job.

[mbs357]

BUT WILL IT FLY

Also, can I custom order one that has a diesel foot warmer? I wouldn't feel right not leaving a carbon footprint.

[lilbrudder32]

@mbs357 steam leaves quite a carbon footprint. More than ICE's do. If you remember back to the early 1900's, the Stanley Steamer car only got about 1mpg kerosene.

[kens97sto171]

@lilbrudder32

Look up Doble Steam cars. 1906-1931 His cars outperformed most gasoline cars of the day. The Model E 1924 weighed 5000lbs, 0-75MPH in 10sec, could move from a cold start in 30sec, 1500 miles on the 24 gal water tank, top speed of 90-120MPH. They were impressive machines. I often wonder if the world had gone that route what the next 80 years of refinement would have brought us. His design with ceramics, and plastics, etc.

[TuxedoRonny]

@lilbrudder32

but the Doble Steam Car supposedly did a lot better. From what I gather the Stanley was the Nissan Stanza of steam automobiles, where as the Doble was the Rolls Royce, and with 100 more years of technological advancement under our belts, we should be able to fair somewhat better in design in the modern era.

[YoungJim409]

I can say with some certainty that this is the coolest thing I have ever seen.

[pilavideo]

nice :D thats like a plane motor :P:D

[permanaization]

This video is very good for study, because I am a teacher in Polytechnic Bandung.

[TrashCanSchool]

steam punk bi plane! awesome video 'you made this?!' O_o

[silverbird58]

dry ice as expandible elelment  !

[av8navig8]

Inert gases, expanding and contracting with enough force to run an engine?.... Surely it can't be done..... and I never heard of Joseph Papp, uh...woops......

[neogastropoda1]

@av8navig8. cool steam engine. did u make this? would it be possible to power an engine off liquid nitrogen? it boils at just above -196 degrees c so at room temp it would boil like crazy. it expands to around 300 times its liquid volume (i think) lol i dunno if water is more lol

i kno its impractical cos of the large effort it takes to produce. wd b cool if u could tho. lol

[jogrannymonkey]

that thing would need a nuclear chamber to keep running long enough

[av8navig8]

You could look up "steam airplane" or "Besler brothers" perhaps?

[jogrannymonkey]

thanks!

[rionrace]

@av8navig8 How's the RPM on this thing? It seems to drop and rise all the time!

[tokejyn]

@jogrannymonkey

and why not? >.> have you seen how long nuclear subs are capable of maintaining a full crew? if you used a large enough scale it would be practical for extremely long flight time... wait, I forgot, to be practical you need to have something to condense. nuclear power works for subs because they're under WATER. where do you propose to fill a boiler in MID AIR?

[jogrannymonkey]

@tokejyn lol yeah thats where i was leading to, in flight u really cant last long if you have limited supply of water. best senario for nuclear power is where u could turn an 'unlimited' amount of water into steam, thus the sub. nice job catching that

[apage251]

@tokejyn You fly through a cloud, or better yet a thunderstorm.. duh. HAHA I know that wouldn't work but I had to say it.

[mbasher2000]

stick your finger in it

[DragonToko]

Steam-airplane!

[frosty9595]

You could sneak up on someone with that.

[JamageControl]

haha id love to see a plane with a steam chimney.

[jogrannymonkey]

ahha!! agreed

[neogastropoda1]

@JamageControl with a funny old man shoveling coal lol

[invertigoupanddown]

@JamageControl hey, did you double check my coal count for this flight

[backflipbushido88]

What's with the cylinder outer design, don't you want to keep as much heat in as possible? Why the cooling design?

[boxa888]

rev that shit man!! rev it!!!!

[madmanmapper]

Oooh its actually running on steam, not like those sissies using compressed air.

[thomvinson]

I would guess they are finned because it is probably a converted gas engine.

[backflipbushido88]

@thomvinson It does say hand built though...

[thomvinson]

That sure looks a lot like a Saito gas four stroke model airplane engine to me, if it actually was hand built then why would they put cooling fins on the cylinders? Most likely they wouldn't! The Saito cylinders were ready made, perfect for conversion, all they really had to do was alter the valving, and replace the spark plugs with the steam manifold. And that is exactly what it looks like they did to me!

[Trailltrader]

@thomvinson

Thats the impression I get- is that it was orginally an aircraft engine that someone changed over- but, it is a good proof of concept idea just to prove it can be done.

For giggles and grins I converted a gas lawnmower engine to steam. Wasn't efficent but it did show it could be done

[Squarerig]

My motorcycle sounds just like this!But why fins?Steam engines need lagging for to retain the heat.Heat=energy.But it is great to look at.Thanks for the clip.

[Robkat3751]

why are the cylinders finned. Would you not want them lagged with insulation for maximum steam efficiency?

[JediMasterKyp]

I need plans for this... I can see about four of these propelling my zeppelin!

[KanineKruizer]

How is this unit lubricated?

[KenMacMillan]

any plans for a double acting version?

[proanti1]

i love the valving...

[azmirkacak]

yes, the rpms are very low... I think if you can get higher power, it will make u fly...

[Shazee083]

let put in one my bike

[J0Boa]

Great , now you cango ahead and build the first steam powered aircraft ! lol

[impavitus]

it wouldn't be the first though

[J0Boa]

I meant the first wood powered airplane

[guitarsncarz]

thats pretty clever

[guitarsncarz]

where did you get a boiler that big to power it?

[av8navig8]

I am using an old pressure cooker, works quite well.

[8inlinea]

brilliant! do you have plans for the engine? it's really great!

[Eviltv4all]

Very powerful, love it! but it has low rpms due to bad compression. if you want higher rpms then shut off about four cylinders and you will notice the difference. you can put ball values between the cylinders so you can have control between the power and rpms. Just giving you an idea if your interested.

[myosat]

thnks for the video now i know how radial engine works... nicee

[M3iscool]

Wow! I would love to build one.

[rabobankeuropas]

amazing

[HeavyDemir]

man I love it .. cudos I whant one ,,,, can u forwarde plans ??

[amberb57]

I'm guessing that you would control the speed with the steam pressure, not necessarily volume. The higher the pressure, the more the expansion in the cylinders. I'm guessing that this engine is capable of fairly high RPM with enough steam pressure.

[filmdude277]

cool

[BushRaven]

i mean steam has a constant expansion rate, compressed air has none or very little.

Air has no tourque to speak of, steam has good torque but not good for speed.

[av8navig8]

Perhaps a bit of speed? care to guess on RPM's of the "converted to steam" airplane motor? ;) in my listing...

[BushRaven]

compressed air may not work as well. Must remember steam expands more than compressed air. Its really great for torque, but not so good for speed as its expansion rate is constant. WHich is why we went to internal combustion which has a scaled expansion rate that can accelerate much faster.

[demonslayer112223]

lol steam fan!!!!!!

[PreacherSly]

be klinda hard to keep a plane going I would think

[Chrutonius]

OH RLY?

...

It's cool just as it is.

[Chrutonius]

I love it!

[boa721]

this would run on compressed air with no problem, even on 20 pounds of pressure would be fine.

[60512]

Compressed air would likely work pretty well with this engine. But I wouldn't have the pressure up too high.

[newagemotor]

That's realy PRETTY ! Looks homemade.

[av8navig8]

I believe it is a one of a kind, hand made. Not from a kit.

[coolestdude80]

Is this a kit or from scratch?
