Rotec Radial Engine 150hp

[@novakinb]

wow that was a pretty sweet engine! 150 hp of air force is crazy

[@Squarerig]

One must derive enormous satisfaction making something so useful and also so beautiful!I am most impressed!

[@maverickdallas100]

@modelleg 1. Radial engines have a crankshaft with a single crankpin. 2. The master rod which belongs to #1 cylinder connects to the crankpin. 3. The articulating piston rods (an even number of them) are pinned to the bottom of the master rod, encircling the crankpin. 4. All of the power is transferred to this single crankpin, so it has to be big and sturdy. 5. Lubricating oil is pumped from an oil reservoir, circulated through the engine and oil cooler, then back to the reservoir.

[@murphyld66]

That is a cool video! I can't help but admire the skills that it took to make that engine.

[@questionful]

so much work and material invested in that thing!

[@DougHanchard]

A cardinal rule with radial's - NEVER have music ruin that sound~! :)

[@kusinagi]

Awesome to have in an interactive exhibit! You've got lots of machines to make this... Could've made a hydro-sterling para-generator for a whole couldntry with all that kit

[@metusa666]

Beautiful peice of engineering precision is where its all at!

[@addemoto]

That is so awesome! Imagine somone building a giant scale warbird for that piece of art. I assume it´s not just for show...

[@n0exit]

@Goliaf1 This is actually a pretty old engine technology. The first internal combustion rotary engine was actually French.

[@landyladv8]

Very nice piece of engineering! Im not too farmiliar with radial engines but just want to know about the lubrication systems on them. Does the oil collect in a sump? Is it lubricated by a pump, splash or mist? Do they get oil starvation when upside down?

[@vincentwalter6529]

As a Jazz hound, and gear head and aviation nut... perfect.

[@k9forkids]

Love the Vid and the Soundtrack, I like how you preserve old engine designs, I hate how everything needs to be a fucking Hybrid

[@Hardcorediver44]

@77fib77 You don't need a separate cooling system,radiator,hoses,ducting, water,All extra weight. Foward motion will keep it cool and running.

[@surinderdhiman]

Awesome! Friend you are blessed with an extra ordinary innovative brain. Keep it up.

[@tailwheelflier]

It'd look great on my starduster too!

[@douro20]

@dan4ouu Sounds about right, considering that all of these engines are built to order and not mass produced.

[@thegoldenduck456]

Wow, beautiful machine you have there

[@RT360ci]

@AltRage it's more interesting how we managed to make the CNC machines before we could get the machines to make precision parts for us

[@Abraxas20012]

i need to get me one of these in my house as a cooling fan

[@ZenMuff1n]

Must be cool assembling those monsters :)

[@FineHawaiianArt]

@AltRage we grinned parts by hand with a bastard file after casting them in sand or plaster via lost wax method which is still viable for some parts

[@MrRedeyedJedi]

im suprised that thing didn't fly along the grass with the guy still holding it! what a cool engine. seriously tho the music is terrible please change it lol.

[@MF11283]

we had these people called machinists who knew how to turn those knobs on a lathe or mill and make the machine do the exact same thing the computer does

[@cordobajvr]

i think the cotter pin is the highest tech you can find to do its job :)

[@TymphaRedbreaduwuowo]

Damn it took this guy 2:30 seconds to make a fully working engine

[@rainmechanic]

How many cubic inches is this engine in the video... how much horsepower/torque to one of these radial engines put out?... Have always been facinated with the radial piston design.. are these electronic or mechanically fuel injected? Did the early gasoline radials use a pushrod actuated fuel injector like cummins/detroit diesels used to?

[@AMikeOnLine]

All that superb engineering.... Ends with testing on......An old 3 wheel traler in an ally way !?!

[@TorcoUSA]

Awesome job, what grade oil does it run?

[@MrROTD]

@AltRage Easily however it wasn't so easy to design, prototype and then manufacture as it is now. The thing I like is 3-d printing, you can make some neat gizmos that are impossible to make any other way

[@antimattercrusader]

I like your music here.

[@hbunnie1120]

This is a great MFG. video. Thank You

[@modelleg]

Questions about the radial: Is there always a "master rod" that is not articulated to the center hub? How are these engines lubricated? There is no sump, so is there a remote reservoir for oil? Thanks to whomever replies.

[@QuasiGenuine]

How with all this technology, have we still not found a high tech replacement for the "cotter pin"?

[@douro20]

What make/model is that horizontal mill? Looks ancient.

[@Ihaveausernametoo]

Excellence. What's that funky tune?

[@wazza33racer]

Nice video :) when can rotec make a 600hp 'corncob' version ??

[@thumasta666]

that engine is pretty big for only having 150 hp.. it does look really cool tho

[@mlong5151]

have to be one of the coolest jobs ever no pun

[@XAuroraM]

Nice work

[@77fib77]

what are advantages of radial engines?

[@Cysiu106]

coś pięknego.Super:)

[@NiMareQ]

This is Art!

[@sbgsUtube]

從無到有產生星型引擎，好珍貴

[@the4x4yamaha]

I would love to operate in the shop!

[@Gravertrain]

If I wanted to hear unrelated music instead of audio from making the video I would go to the "You Speaker" web site. I agree with bacon546psn, thank you.

[@vincent7520]

great ! how long did it take ?

[@LTDZach]

Beautiful!

[@sbdem1986]

Total beauty.

[@douro20]

What material are the connecting rods made from?

[@bigflipo]

Thats art man

[@Gavs_rc_hobbies]

@minibikerider1 it could happen, i saw one youtube vid where a guy was running a radial engine on a small trailer like that and when he gave it a good rev, it started to take off towards the crowd!

[@Asdayasman]

I dunno what I just watched, but it was badass as fuck.

[@djyul]

Excellent!

[@burnbabey12]

@fb2800 Dual ignition?

[@UmbertoNURS]

-Che bel fresco... -What a nice cool...

[@cup_and_cone]

Only 150hp from all that? I'm guessing the tq is significantly more, and that's what matters?

[@HatzR3600]

3.6ltr engine 150hp, Carburetted, This is not a diesel engine, standard spark petrol with pushrod operated OHV , 2 valves per jug.

[@mikser6666]

thats beautifull

[@allanrussell353]

Very nice.

[@booberryr5696]

how muck do it cost to make me an engine like that?

[@Nighthawke70]

Just think if you had to assemble these engines during wartime.

[@Cryndyne]

@AltRage its called, someone would make one and just not call it a CNC but it would be the same thing!

[@flybazman]

Great engineering but why only 150 HP? That's a lot of extra weight to lug around aloft for just looking good!!

[@AltRage]

How did we ever survive without CNC?

[@ctophu]

they should drive that down the street like that lol

[@dykta666]

wow.respect

[@themainproblem]

Sorry, But I am going to have to report a mechanics porn violation. Great video!

[@kolby4078]

i just feel like it should make sooo much more power....

[@Anonymous5211987]

they should make an airboat! :D

[@gus23a]

how much is it?

[@superskullmaster]

@jackle3002 You don't know much about aircraft engines then do you. They are large for the horspower they produce because they are all about torque.

[@ahz123]

Tremendous.

[@MARSPALMA]

2:58 - How fast?

[@Goliaf1]

Great American Ingenuity

[@Roborossie]

@the4x4yamaha Me to!

[@LimitedWard]

Try not to let that roll away XD

[@TheGoodInventor]

ur amazing man gd jb

[@RustyNex]

i want it in my car!

[@bob119911]

the song just completed the vid

[@13396357]

nice

[@vector6977]

Things just took a lot longer to make.

[@burnbabey12]

@gghouck You learn something evryday :D

[@XDFreakLP]

imagine that man falling over in the propeller @.@

[@bearbon2]

Would have been nice to hear the engine crank up, idle and run up without the goofy music.

[@SamGSE]

Interesting

[@ice777nice]

15000$ ?

[@andrepatacchini]

The music made the video

[@NOBOX7]

only 150 hp ? r u shure it aint 400

[@ehle]

I Admire Your life!!!

[@budasakyamuni]

Beautiful engine! The music AWFUL ??

[@Ryan57Garr]

I thought I saw legos at 1:10

[@Taydrum]

throw an apple in the spinning blades!

[@thefavs]

♥♥♥♥♥♥

[@tazztt1]

=.)... I... I... I have no words... gulp.

[@firmclock]

stick it on a go cart

[@WetVidz]

now build a motorbike to put it in

[@derranged28]

Shouldn't that propeller be enclosed by some sort of cage? Safety first, dude.

[@WarblesOnALot]

Well, I enjoyed the clip; & who cares about the music..! And, when's the Rotec- Bentley BR2 Rotary likely to show up ? Pretty Please, the Ultralight Sopwith Snipe just simply WON'T WORK with a Radial... Get onto it, surely ! Meantime, to see NASA riding backseat to a Hillbilly, search 'solar thermal ramjet'; & it's all true ! Search 'sunfoil' for the backstory. The "Short-Talk" clip's the best entrypoint of an interlocking suite of clips. Open Source, enjoy. Ciao !

[@urgdaddy]

Music is pathetic...how about something low key, smooth and background. It's the machine process I'm interested in.
