@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").

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.
@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).
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
@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.
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.
@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"
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
@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 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.
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.

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.
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.
@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.
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.
@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.
@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.
@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.
@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
@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.
@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.
@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.
@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!
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 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 It is a rotary engine. Rotary engines include both the early WWI rotary design and the later 1950's WANKEL rotary. This is not a wankel rotary, but it is a rotary engine.
wikipedia. org / wiki / Rotary _ engine (delete spaces)
@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.
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
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.
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.
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
you should make it into a fan, just for the lolz

@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 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 1 year ago
@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 1 year ago
@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.

@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

BanditDragoon 1 year ago 7
@BanditDragoon It's a rotary. The French invented the Gnome rotary long before Wankel's masterpiece. Do the research.
popnstart 1 year ago
@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 It is a rotary engine. Rotary engines include both the early WWI rotary design and the later 1950's WANKEL rotary. This is not a wankel rotary, but it is a rotary engine.
wikipedia. org / wiki / Rotary _ engine (delete spaces)
Bamchucknorris 1 year ago
@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).
SilntObsvr 1 year ago
@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.

A radial engine rotates the crankshaft
A rotary engine such as this rotates the engine block.

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.

Notice the 10 holes in the Sun gear. I used Autodesk Inventor 3D software( Autocadd 2D as the imported sketching tool).

Saves ABS(US$12.00 a cu. in.) plastic and the teeth are tougher
