  • you should make it  into a fan, just for the lolz

  • Beautiful work.

  • @buddyl962 , thank you for the positive comment. Later, Rick.

  • Why rotary? why not Radial instead? where's the valve gear or ports? do I ask too many question? What shall I have for lunch?

  • @MrROTD no,no, never too many questions. Rotary because I had already done the radial(see "6-cylinder Radial Engine with 4 to 1 PTO"). The valve gear and ports can be seen in another upload entitled: "Autodesk Inventor Rotary Engine Components) video. All major parts are drawn with the 3-D software. How about some round food for lunch: PIZZA!! Thank you for your interest. Later, Rick.

  • I am extremely sorry if I hurt u with my comments. The previous video was not showing full details, that is why I could not get it properly.

    But this video explains the every detail of your amazingly invented device. This is really really a MASTERPIECE at every aspect and will be very useful in future.

    I feel sorry again.

  • how much does it produce?

  • @calito0010 , i dunno, but there is probably formulas where you could plug-in the bore(1") and the stroke(1.5") and the air pressure(140p.s.i.) to get a ballpark figure. I would guess 10-12 h.p.(hamster power).

  • @popnstart

    a 1" bore yields .785in squared. x 140 psi = 109 lbs of force.

    Transmit that through a .75in lever arm (1/2 the stroke) and you get 82 lb-in which is 6.86 lbs-ft. (Torque). HP is torque times angular velocity (rpm in radians per second; 1,000rpm equals 104 rad/sec). 6.86lb-ft x 104rad/sec = 718 (lb-ft)/sec., multiply that times the conversion factor to get 1.306 HP.

    HP = 1.3 @ 1,000 RPM and 140 psi, theoretical. Not a bad little motor

  • @RenegadeEngineer * 6 cylinders = 7.8 HP. Bad ass.

  • @RenegadeEngineer Maybe keep the PSI down on testing, you got some power there. Dont want to strip the acrylic.

  • Cool stuff pal. But I see no form of lubrication... Fill me in please, Im interested !

  • @MuhammadDerkaDerka , at the top of the aluminum bracket a screw covers a hole. Occasionally, I drop a little oil in it to lubricate all the moving parts when the oil mixes with air. Later, Rick.

  • what song is playing in the background of the movie ?

  • @nohalopagus , I don't know. Just a YouTube tune clip from the audio archives that were about 1 minute long.

  • really cool design encompassing the planetary gears, but the centripetal forces of the cylinders rotating will cause whatever the engine is mounted to, to torque-twist in the same direction once more fuel enters the cylinders, thus sending its host into a barrel roll.(gyroscopic inertia)

  • @imstricken06 , seems I have read sometimes the pilot used that phenom to their advantage during a dog-fight. Those dudes probably had to carry their rocks in a wheel barrow.

  • @popnstart It's called p factor and yes you can use it to your advantage. That thing looks incredible, great work!

  • how you feed the fuel to cylinders? rotary fuel tank?

  • @Mr18doug ,uhhh....yeah the air "fuel" is directed to the cylinders thru the 1/4" plastic tubing. The "fuel" is produced by the rotary fuel tank(air compressor). See vid "Rotary finished and pushing air"

  • You will need to rotate the compressor too.....smartass!

  • @popnstart

    Wow. Hell of a dick move there, mate.

  • @popnstart nice work, but the music is annoying

  • Is it working or is it just a project? It's really nice

  • @1000900903 , its finished and running whenever there is air hooked to it. Now, the new "play-pretty" is the miniature hit-n-miss project.

  • verticopter 

  • There was writing on the front and I could spin it. It had the clients name on it, "built by" he said when you put air in it, it goes fast and you couldn't stop it by hand

  • Where is this? i saw one today at a job and i want one.

  • @BlondellTheWell , it is in the MTSU Engineering Technology machining lab. It is the Advanced Machining class project. The students make the parts and it is theirs to take at the end of the semester. This project was replaced by the miniature hit-n-miss engine project shown operating a can crusher on my channel. Sorry, but the only way to get one of those rotaries would be for a former student to sell his on e-bay, etc. Thanks for your interest. Later, Rick.

  • This is positively a rotary engine guys. You seem to have the idea that a rotary engine is configured like the Wankel or Mazda. It actually dates back to the first world war.

  • The centripetal forces of the cylinders rotating will cause fuel to pull in a vector outward, perpendicular to the direction of rotation. Have you ever tried to move a spinning wheel already in motion to a different changed X/Y/Z axis? this looks great on paper but in real world applications i do not see it working at all - the plane you put it in would have to be much larger than the motor to force the motor to turn, otherwise the motor will turn the plane.

  • @evhgl87 They used to use these as WWI plane engines.

    They do work

  • @thegoldenduck456 i meant this physical motor, not a plane that has the weight to motor ratio i have mentioned.

  • @evhgl87 Even when they used to use them in planes they were tricky, If the pilot accelerated/decelerated too suddenly the torque of the engine spinning faster would roll the aircraft.

  • this is not a rotary engine.

  • Nice!! Wow, I am jealous of your skills. Everyone is seeing a rotary engine, but I am also seeing planetary gearing. So maybe we could call it a " planetary rotary engine "?

  • @tld5500 , thanks for the positive comment. Thanks for acknowledging the rotary style engine. Every part was drawn with the CAD software. I think learning the cad software has helped me to design stuff more accurately and may help you too. Thanks for your interest and I subbed. Later, Rick.

  • @popnstart , thanks for the support. I agree. I have been resisting learning CAD, because I did not want to spend more time learning a program than I had to build a machine. But I see I was wrong. Also, I need more machine tools.

  • Hi, This is not in any way a ROTARY engine, it is a rotating engine. Don

  • @donmaguire , one is an noun and one is a verb, so, thanks for helping make my point. We just keep going 'round and 'round with this discussion! (pun intended)!!

  • @popnstart no you wont because the rotary engine is only practically used by mazda.

  • @donmaguire

    I think your confusing Wankel engines with original rotary engines or radial engines, this is a rotary engine and they were popularised in production long before wankel rotary engines were on the scene, so this is a rotary in the true sense of the wording and your think of a wankel engine to give it its proper name.

  • @donmaguire Actually, this IS a Rotary engine. Look up a Gnome rotary on google.

  • @donmaguire - It is a radial engine, like WW1 fighter planes.

  • @edgewayround , you hit the nail on the edge. Thanks for the help. Later, Rick.

  • The truth is that it is both Radial AND Rotary, it's also very nicely made.

    Thanks for sharing it with us.

  • @ozzirt , I agree. It is a rotary engine(cylinders rotate) in a radial cylinder configuration(cylinders are radially offset). Thanks for the kind comment and your interest. Later, Rick.

  • @popnstart The world it seems, is full of "experts", such a pity that so few of them know what they are talking about. :-)

  • @ozzirt , hopefully this wonderful medium called YT can help change that.

  • @fozzersmisterlister It's a ROTARY - the cylinders spin around the crankshaft.

  • From reading your comments to peoples comments I have decided that you sir are a fucking faggot that thinks he is all high and mighty. You will be avoided when I watch youtube from now on cause you do not deserve the views.

  • @fozzersmisterlister , they were referred to as rotaries long before Dr. Wankel invented his legendary mechanical masterpiece. I suggest doing the research on a subject before commenting on a vid to prevent embarrassment. Here's a starting point: Search on YT "Gnome Rotary". Thanks for your interest.

  • @popnstart If your not embarrassed then your not learning !

  • so that hex shaped part on the back is the cam that controls when the air is injected?

  • @jack9102 , no sir, that hex shape just happens to be the shape of the material that has been in the steel rack for the last 50 years. Please watch the video I uploaded "Autodesk Inventor Rotary Parts" to get a better idea of the operation of the rotary/radial engine looking at the parts drawn with 3-D softare. Later.

  • nice music

  • @Dubconferencedotorg , thanks. It's the best I could find at the time for the length of the 1 minute camera limit.

  • I don't know, any Technology associated with wanna-be boy band music I immediately trash and stomp on. No offense.

  • @Merlin5x5 , no offense taken. Thank goodness Youtube has admonished upon us all, the sacred mute button, which I expect most folks, including myself, have used to make a vid more enjoyable.

  • @popnstart Your obviously not an idiot. But, you can always learn more about any topic no matter how old you are. And, i didn't del anything (except my posts here). I am sorry if I offended you in anyway, that was not my initial intent. PS: It is only fun troll Justin Beiber's Baby song :)

    Lamboragon 44 minutes ago

    Sorry, don't know who Justin Beiber is, but have heard that name, so have fun with it I guess.

    Thanks for the apology Lambo, you are a better person for it. 

  • @Lamboragon , Uh.... you sent this at 1 A.M.! Dude you stay up way too late to waste time on someone you called an "idiot"LOL. No rage here. I'm now content. Sorry you had to delete your FB, Photobucket, and LinkedIn accts. Based upon your publicized merits, you are a better Engineer than a Youtube troll, so concentrate on that so myself and others can get a more professional opinion of their uploads. Apologies are in order, so stop making mean comments or I will have a talk with Dean Mashayek.

  • @Lamboragon , well Lambo, thanks for the nicest comment I have seen you write. BTW,you had a chance to make video comment retractions and chose not to. You might have the "book" sense, but DANG DUDE, you lack in the common sense. Good luck with your career. LOL

  • @Lamboragon , Patricia, you got some mighty friendly friends who are so helpful helping old friends find other old friends on FB. What other smarty-pants comments you gonna make now, boy? Eagle Scout, huh? Thats whats really hurts. I think you should return the Merit badges you earned. What the heck happened to you? Are you so stressed with school work that you need a release, so you disrespect other people? Time to get your act together and grow-up boy. Your chance to retract. Git-er-done!!!!!!

  • @Lamboragon , Hey everyone, Lambo must be "really drunk" when he negatively comments on my "Engineering" knowledge. Don't believe me?? Well just search youtube for " GEAR SPHERE" by "Majikman111". Ok, please someone tell me Lambo is not the future of our engineering fraternity. NOOOOOOOOOOOOOOOOO!! Lambo, be careful what you type from now on because it will always come back to bite you in the butt. And, oh yeah, lay off the sauce. Its a dead-end and you seem to have potential.

  • @Lamboragon , ok Lambo, the ball is still in your court. Educate us. Surely, you have noticed by now I don't delete negative comments and I allow equal freedom to idiots and smart folks to post. Besides, how else are you gonna distinguish them if you don't let them express themselves and let the consensus decide. So, please, feel free to post some inspiring and useful information.

  • @Lamboragon , ok Lambo, we are all waiting for your methods and demonstrations, since you claim to be "in Engineering" on one of your video's. Thanks in advance. BTW, why all of a sudden you disable comments on both of your videos after deleteing the comments?? Are you a little sensitive?? I didn't say any bad words or call you any names as you did me. Come on now and show us or tell everyone. There are 500 characters available.

  • @Lamboragon , well then, Lambo, I think I'll use POPNSTART's methods of drawing TRUE involute gear tooth profiles by following, closely, the following videos he has uploaded using Autocad software: "Autocad External Gear Demo", Autocad Internal Gear Demo, and "Autocad Gear Tooth Procedure" (Word document scroll thru). That should really make the gears I make run smoothly with constant pressure and tooth contact surface velocity. Thanks to you for your encouragement to do better.

  • Very impressive. Has it run on compressed air yet?

  • @akumabito2008 , Yes sir, check out the "rotary finished and pushin' air" vid. Thanks for the kind comments. Later.

  • I admire your skill and expertise.

  • @Squarerig , thanks for your kind remarks.

  • It's way cool, hope the plastic hold up

  • @grizz474 The clear acrylic(.215 thick) is brittle and will crack and break if exposed to too much shock. Thanks for your kind remarks and interest.

  • @popnstart what s the name of the song? :D

  • @inginerul1987 , brother I have tried again and again to find out the song's name to no avail. Sorry. Can anybody else help us?? Later.

  • Sound as though you know your old engines. That Mazda wagon seems like a rarity too, especially with a Wankel under the hood.

  • Radial engines have fixed cylinders, Rotary engines have cylinders that rotate with the propeller like the World War -1 French Le Rhone engine. The revolving cylinders provided better cooling than the fixed Radial engine. The modern use of the term Rotary engine when reffering to Mazda'a version of the wankel was a marketing ploy by Mazda because they considered their versions to be much more advanced than the engines built by NSU-Wankel. I had a 1974 RX-4 Wagon that lasted 11 years.

  • whats the sence of this ''engine''

  • @Miisch44p whatever you want it to be. it's your world, let it happen.

  • @tallblondesexy It was a rotary engine, as the entire crankcase spun, even in the early WWI design. The french engine company was named Gnome et Rhône.

  • @tallblondesexy  I was thinkin' it was the French that made the Gnome(pronounced Nome).

  • @tallblondesexy actually the balance is better than the radial. no reciprocating parts.

  • I remember how floored I was when I discovered this style engine with the spinning cylinders, it seems so illogical. I've always been fasinated by them and how they fuel and provide spark, I remember seeing an ancient step through motorcycle with one in the front wheel, a five cylinder it seems like, how bizzaire it was. You do real nice work, and frankly I liked the music. What do the planetary gears do? is that what the prop would be driven by? I'm not intuitve when ti comes to gears.

  • @505197 ,Yes sir, the prop is bolted to the sun gear which is driven by the 3 planets that rotate at engine speed. The helical gear material is ABS plastic created from a 3D Inventor(Autodesk product) drawing and built in a Stratasys 3D prototype machine(Fused Deposition Modeler). Thanks for the kind comments and I appreciate your interest.

  • Woha! cool engine! I'm curious though, what made you make a rotary vs. a radial?

  • @gizmoguyar , there were several radials built before I decided to design the rotary version. With a rotary their are more components spinning, etc. and the centrifugal and gyroscopic effects make for better oiling(oil/air mist exhausts from crankarm) and a higher rpm, respectively.

  • most annoying song ever

  • @Joeyad4 Mute works pretty good

  • @popnstart cause i thought u were gonna talk

  • @Joeyad4 Didn't talk because youtube was new to me and I only had a digital camera to take my vids. Santa brought me a digital Video camera for Christmas and a whole new world opened to me. FOLK's, any vid of mine with that tune playing I took with a digital camera!! You gotta admit the clarity of a digital camera is pretty good after youtube gets finished fine tuning it. Later.

  • song name?

    thanks :)

  • @nosrorro Don't know. Got it off youtube

  • hi!

    nice engine, great job man

    what is the name of da song? :D

  • @nosrorro Thanks for the kind comments. The song was one i picked from a YouTube list that is close to the same length of the video. This was taken with a digital camera so no sound was available.

  • What is the point of building this air engine?

    What do hope to achieve?

    What are its advantages over other engines?

  • @NearAbbeyRoad  Fuss qwershun: it's fun to build. Sekun qwershun: no standunder sekun qwershun. Turd qwershun: it's fun to watch it run.

  • It would be very cool to have the means to build that piece. Hats off to you partner. What is that song? Sweet guitar riff.

  • @JoeTeamMayhem The song is one I selected from youtube that was similar to the length of the video.

  • more vehicles should use rotary engines they're superior to regular piston engines in every way

  • @chevygearhead454 Hmmm... ok...I'll bite... name just 2. Then, tell us why the Wankel rotary isn't in 99.99999% of all vehicles.

  • @popnstart They make more horsepower with less displacement then a piston engine and have a way higher RPM range and I guess because theres very few rotary engine technicians for there to be a real market for them

  • True art

  • @bearlakeburton  Thanks, brother.

  • what do u do for a living? are you an engineer?

  • @BLOODYKnuckles2000 A tool and die maker by trade. I lack the math skills to be a "real" engineer. But I enjoy designing stuff and then I get to make it.

  • @popnstart very cool :)

  • @BLOODYKnuckles2000 Thanks, brother.

  • where do you buy those gears???

  • @Rabbit12100 i draw them and the prototype machine builds them from the drawing. made from abs plastic. cool huh!

  • This is a radial engine, not a rotary. Rotary engines do not have cylinders.

  • @Deathadder422 The French made the Gnome Rotaries for their WW1 biplanes. Of course, this was long before the genius of Mr. Wankel. Yep, it is a rotary. History lesson over.

  • Brilliant work, we need more craftsmen like you!

  • @radzai Yep, the old "hands on" is slowly a dying art. We need more young folk getting interested in this stuff and I'm trying to do my part.

  • THIS DAMN SONG IS STUCK IN MY HEAD NOW

  • nice build but seems overly complicated and fragile for little if any gain

  • @DanFrederiksen , thanks for kind remark. Yep, lots of parts, the acrylic is fragile, and it won't fly. At least the utube people thought it was worth a posting.

  • @popnstart the cylinders will be locked in place right? to the outer ring of the planet gear. otherwise it doesn't make sense

  • @DanFrederiksen Yep, the cylinders will lock-up if a few drops of oil are not applied thru the screw hole in main bracket. The cylinders rotate with the planet gears. The Ring gear is stationary, Yep! Sun gear turns 6 times faster. Yep!

  • Very well job dude! Hold on!

  • @JeyBee66 Thanks for all the kind comments folks. Later.

  • its not a rotary engine ( used by mazda and also known as the wankle engine ) it is a Radial engine layout ( yes i know im being rather picky ) but this looks so very awesome

  • @BanditDragoon It's a rotary. The French invented the Gnome rotary long before Wankel's masterpiece. Do the research.

  • @BanditDragoon A rotary engine is any in which the combustion chambers rotate, so this IS a rotary engine, as is a Jet engine, and more recently the Wankel. Radial engines were made both ways - about 100 years ago the rotary radial was common, but with advances in cooling fin design the non-rotary radial became de rigueur.

  • @BanditDragoon Actually, this *is* a rotary engine, roughly similar to the LeRhone and Gnome rotaries used in aircraft during the First World War. The difference between this and a radial is that the radial crankcase and cylinders remain in a fixed position, while in this engine the cylinders and crankcase are rotating around the fixed shaft (though here, unlike the WWI versions, the small gears drive conventional valves in the moving cylinders, rather than the way the old engines did it).

  • @BanditDragoon In a radial engine the pistons do not rotate. This is a gnome rotary engine where the crankshaft is stationary & the pistons rotate. It was used on WWI aircraft & BMW put it on a front wheel drive motorcycle called a Megola. If you google it you can find some cool animations of how the internals work.

  • @BanditDragoon rather picky lol its a radial.. sweet job dude... I dont think a wankel rotary would work very well given the weird figure 8 they do.

  • @BanditDragoon

    A radial engine rotates the crankshaft

    A rotary engine such as this rotates the engine block.

    Everyone gets confused with the wankel rotary it seems!

    Check out the Gnome Rotary engine out of World War 1 fighter planes.

  • beautifull

  • This is art, fantastic!

  • f that johnny help me finish my project,a gun that fires lead balls that uses gasoline+air,and a pocket ball rerounder so when you fine stray balls of lead you can re use then in your g( oh no a black helicopter is landing out side an jessie venturas clone is coming my way)I new this would happen

  • whats song?

  • I dont know engines but that looks awesome! Well done

  • To much force required for sustainable rotational surplus.

  • @bimmerdoc79 steam by solar preheating

    could get you closer

  • Not to mention those gears are going to be grinding away in no time!

  • @bimmerdoc79  Runs on an aquarium pump. Now, thats a lot of "force".

  • is that wot u call a "frictionless" motor?

    thats amazing.

  • frictionless is impossible

  • KAPTAINKOOLZ,

    b4 we begin, i need YOU 2 define wot friction is.

  • the force that resists and puts drag on objects that move against one another

  • KAPTIANKOOLZ,

    on a cosmic scale, the earth orbiting the sun is frictionless motion. on a molecular level, atom orbiting a nucleus also doesnt exhibit refiction. therefore, i conclude based on the available evidence, "frictionless" exists.

  • i cant comment on that, since i dont know anything about it!

  • KAPTIANKOOLZ,

    do you know why diamonds are so rare?

  • because DeBeers enjoys controlling the price/quantity : ]

  • KAPTIANKOOLZ,

    no.  just like the germs the live on germs, very few are looking for them.

  • As long as matter is present, there will always be drag. Doesn't matter how big or small the scale is.

  • IRAI1984,

    and wot of anti-matter?

  • what of it?

    You have an 'anti-matter' powered engine?

  • IRAI1984,

    fund my research, and ill build u 1 within 10 years.

  • if someone funds my research I'll build one with-in 6mos.

    idiot

    make sure you get a beano clause -

    be no body leaving with the money for South America !

  • vey nice but i don't see how it would be used to run a vehichle

  • bro, this is amazing. congrats it really is a work of art

  • Is this thing in Tennessee?

    Ive seen something very similar there.

  • Yep, this is in TN. BTW, this is suprisingly my most viewed vid. Where are you folks getting the link?? Thanks for all the kind comments.

  • If I had looked at your page I would have seen it. I'm from Alabama and went to Nashville a couple months ago, and visited a car museum there and saw this in the corner. I think it was a group of people who made this. You all did a good job on it.

    I found it by looking at the rotary plane engines, in the related videos.

  • Dude, definitely more than 5 stars! Nice colors.

  • sick!!! good job dude :D

  • plz can you give a date of when its done.

    i realy want to see this in aktion

  • Brother, it's been done!! See it running amoung other popnstart vids.("...finished and pushin'air") Thanks for your interest in this stuff.

  • can you sent some kind pls send some kind of date of when it wil be finnisht...

    i wanna see it in action...

  • Awesome.  Plastic gears won't hold up, however.

  • Notice the 10 holes in the Sun gear. I used Autodesk Inventor 3D software( Autocadd 2D as the imported sketching tool). I build the part in the 3D prototype machine hollow and use the holes to pour 5 minute epoxy that infiltrates all the way to the helical teeth. Saves ABS(US$12.00 a cu. in.) plastic and the teeth are tougher

  • looks like it would make a lot of rpms

  • Prop turns about 2900 with 6 to 1 planetary. Engine about 1/6th of that.

  • wow excellent work.

  • Thanks for kind comments. Best regards

  • Oops... How will "it" work?

  • How will is work... i wanna see it in action!

  • It is amoungst my other vids. Later.
