Solar Saturn Turboshaft Engine

[@Max_Marz]

in the us, and I'm sure Canada too we had microwave radio towers between the 60's and late 80's run by att/bell called "long lines" they carried all long distance telephone calls and sometimes secure government comms most profilic during the cold war. at some of the more important relays that dealt with multiple wireless interconnections often in very remote locations they used these solar Saturn units for backup power. long lines played a big role in our history and many don't know anything about it.

That's a really old Solar Saturn. They were owned by IH in the 60's and early 70's. I've done a lot of work with Solar over the years. Great company. I've never seen a.cutaway except st the factory in SanDiego.

Very cool. I worked in fuel nozzle manufacturing as a manufacturing engineer and have made the Solar Saturn fuel nozzles. Really cool to see them in the engine.

[@SquillyMon]

I'm constantly amazed at how well made these machines are... The attention to detail, the beauty of the parts and gears and subsystems...just everything. I'm a Gear-Head...so I tend to appreciate these things, when other people just stare and shrug, I seem to stare and smile or sometimes drool but I digress.... I guess I'm a weirdo ...oh well

[@Phoenix-ej2sh]

Love seeing new things in the shop.

[@Jangle2007]

Great video! You know, somewhere back in "Questions" (#56, I believe) was my break-through moment to finally grasp the "how" of compressor blades and stator vanes work together to increase pressure in the compressor section: compressor blades accelerate the air mass through a convergent passage, whereas the stator vanes are a divergent pathway, slow the airflow, and therefore compression happens. Expansion = compression in the stators?? I didn't understand.... The lightbulb moment occurred when agentjayz said the magic words: "this is part of the Bernoulli equation." I mention this now because it's fascinating to see in cut-away detail how the process reverses with the working air doing work in the turbine section. Thanks for an excellent tour through the Solar engine.

[@AgentJayZ]

Excellent. Thanks for using your thinker and your reader to increase the size of your understanding.

[@grahamj9101]

You're not quite there. OK, the annulus profile from front to rear of a compressor is convergent, to maintain an approximately constant mean axial velocity. However, the passage shape formed between two rotor blades is not convergent: even at the tip of a big fan blade it might be virtually constant, but at the root it will be divergent.

[@Jangle2007]

grahamj9101 - Ahhh...well...I enjoyed my moment of understanding while it lasted. Because you opened the door, are you open to providing further information? Your post immediately raises two questions for me, which in this context I presume apply to only the fan of a turbo-fan engine: 1) The passage shape formed between two [compressor?] rotor blades is not convergent? Does this statement refer to the passage between fan blades or (core?)compressor blades? 2) Is the purpose of a divergent passage between fan-root blades to control/slow airflow into the core compressor? If so, is this purpose to prevent supersonic airflow from entering the engine core? If the passage is divergent, Bernoulli says the pressure should increase...does the pressure actually increase here before the compressor stage? All the best to you.

[@grahamj9101]

You are obviously clear in your mind that fan and compressor stator vanes form a divergent diffusing passage, to convert velocity into pressure. However, you do need a little more sorting out in respect of rotor blades. Basically, my comments apply to both fan and compressor blades. After all, a fan is a single-stage compressor, but with an extreme hub-tip ratio. Fan and compressor blades form a divergent passage at the roots, with the divergence reducing towards the tips. And yes, there is some pressure rise in the rotor blades, which is compounded in the stator vanes. And no, the fan does not slow the airflow into the core: however, do not simply think in terms of velocity change in the axial direction. The big changes in velocity take place in the circumferential direction. I have to hand my retirement presentation piece from R-R, back in 2003. It is a mounted IAE V2500 HPC1 rotor blade, which I have measured as best I can at the blade root. The inlet passage width is about 19mm and the outlet width 26mm. The tip section has minimal curvature and cannot produce any significant divergence: equally, it cannot produce any convergence.

[@grahamj9101]

I've now measured my Pegasus first stage fan blade. At the blade root, the inlet passage width is about 42mm and the outlet is about 55mm. These dimensions (and those I gave before) are not, of course, the chordal distances from one blade to another. They are, for the inlet, the dimension from the leading edge to the nearest point on the convex surface of the adjacent blade: for the outlet, it is the dimension from the trailing edge to the nearest point on the concave surface of the adjacent blade.

[@jfan4reva]

Just watched a video of a Solar Saturn electric generator start up. They showed the engine rpm percentage gauge, and the exhaust temp gauge. They both slowly climbed up to 45% and 700 degrees respectively. The engine rpm kept on climbing to 80% (temp still 700), then the rpm surged to 100% and the temp dropped to 500 degrees F in about 2 seconds. The rpm increase wasn't too shocking, but to see the exhaust temp drop that suddenly was. The power turbine really does suck the energy out of the exhaust!

I live in York, Pa where Caterpillar was one of the biggest employers in the 80's and 90's. I remember shortly after cat bought solar, they built a six unit Solar Turbine powerplant at the cat plant here. I am pretty sure it is still operating. it was a 58,000kWe plant when it was built. I am a little young to remember but York used to be a vast industrial powerhouse of a city. Not so much anymore. It's kind of sad seeing all the disused factories here.

[@doxland]

I heard a Solar Gas turbine run up at Camosun College Diesel shop 20 years ago. It's size compared to a similar output Diesel what remarkable. The sound was ear damaging; I suspected at the time that it was mostly gear noise? The spur gear you describe probably confirms this. Exhaust was routed out and up over the building so the noise all came from the engine room. To me, at the time as a learning student; It was alarming Helical gear noise; the choice for the ears.

[@robinwells8879]

What a treat! Exquisitely beautiful is really not an overstatement. Many of the units you show us have more artistic merit than many of the sculptures that I have ever beheld! Beauty can be fitness for purpose I suppose but even then it doesn't fully explain the appeal for me. That Saturn exhaust duct is positively voluptuous! I thought I noticed that the individual hot stage turbine blades did not appear to be separate inserts within the discs. There appeared to be no vibration damping looseness in their mounting. Are my eyes deceiving me again?

[@grahamj9101]

No, AgentJayZ, I didn't immediately recognise them as Speys under their fluffy white insulation blankets. Please remember, I was never a Derby man, but found myself working on military Speys when responsibility for them was transferred to Bristol. What are they? Mk.512s?

[@MegaFPVFlyer]

Practical.

[@Xiph1980]

I think the reason why you generally only see radial boxes, is because they are lighter, however they're also more prone to alignment problems and they are slightly less efficient due to more sliding surfaces in those crown gears. However for aviation purposes the weight factor overrules the efficiency and more expensive parts, assembly and maintenance. I would have expected the exhaust to be more snail house shaped by the way. Interesting. 😊

neat little turboshaft

[@IIIIITIIIII]

Awesome video! I overhaul these bad ass little turbo shafts for a living. I'm curious, maybe you were too and checked. What are the blade tip clearances of the turbine rotor blades, and the compressor rotor blades of the engine in this video? It looks like the compressor rotor blades have some pretty decent rub, couldn't tell on the turbine rotor blades. Also you said it was 1,000HP. Do you know if it's a Saturn 11, 12, 13, or 1,400 model? It's clearly a Saturn 10 series, I can tell based off the compressor case and combustion case. Saturn 20s have slightly different design for the diffuser, combustion case, and compressor case. They are thicker/heavier. Also the accessory drive/air inlet on that particular engine are MK1 version. The starter would be connected to the gear box parallel with the engine.

[@AgentJayZ]

I didn't know any details about this engine then, and nobody who worked on it will remember it now.

[@todddembsky8321]

Jet Porn on a Saturday morning. What a beautiful job on the cut away. I have to say that it looks like something International Harvester would make. That is one beefy case on that bad boy. Made for the farm to last many generations of owners. (not really made for the farm, but the analogy is the same -- it will last forever if taken care of)

[@grahamj9101]

Apart from the intake casing, which AgentJayZ tells us is in steel, it appears to me to be a relatively lightweight machine, as compared to the big industrial heavyweights.

[@todddembsky8321]

grahamj9101 Well good Sir, I cannot argue with the Master, the internals are probably light weight compared to a 40,000hp gas generator. But you have to admit, that accessories case looks a lot like a Power Take Off from a tractor :-) Hope all is well over the pond.

[@grahamj9101]

Apart from that intake casing, the rest of the engine casings look only a little heavier than an equivalent aero engine. However, we can't see what the compressor rotor looks like and I can't find a cross-section on the internet. It could be quite a solid steel lump and fairly certainly it wouldn't be in Alumin(i)um or Titanium. Things are OK over here, thank you - apart from all the issues over Brexit, which will probably continue to plague us for years to come.

[@todddembsky8321]

grahamj9101 You have the Brexit, we have Clinton and Trump -- ever think about moving to Jet City and rent a room from JZ :-)

[@grahamj9101]

Well, it was reported here that several American A-list celebrities had threatened to move to Canada if Trump won. However, with advancing years, I'm feeling the winter cold more keenly and, seeing the snow in Fort St John, that's putting me off. If I do bale out of the UK, I think that I would join my daughter and family in Singapore - and complain about the heat and humidity. There might be snow in BC, but this afternoon, I mowed my lawns, probably for the last time this year, and cleared up the fallen leaves.

[@abebarker]

It looks like the ring gear is missing from the planetary reduction gear set of the Solar Saturn exhaust duct. Obviously the ring gear would be the power take off. I see the planet carrier is fix to the exhaust duct which means the planetary gear set will operate as a simple reduction gear, i.e. one input, one output. Pretty neat.

22300 RPM. Either 500 KW or 750 KW (500 on PRO, 750 on ALG). 1200 HP rated, Air started, with 600 PSI air used to start it. Yes, offload when started, ITT7 had to stabilize before it would go on load. #1 (280) and the GT (PRO) would both be setup to go on auto load.

[@almcinnis3248]

What is the clearance between the shaft and the stationary blades at 12:57 ?... 0.010 inch or less? Thanks for the videos, very informative..

[@AgentJayZ]

That clearance is a small as practically possible, because it allows air to leak, which decreases compressor efficiency. 0.010" would be good. Modern airliner engines strive for just about zero. It's not that important in conversation, but I feel compelled to let you know that what you are calling the shaft is actually a spacer, mounted on the shaft between two compressor discs. Some engines are built without a shaft, and the blades are mounted in a "drum", composed of what would be the discs and spacers in more conventional designs.

[@almcinnis3248]

[@robertthurman3743]

Jay, you made a comment that if an engine gets much smaller, the fuel efficiency goes down. Is there a sweet spot for hp vs fuel efficiency? Obviously they type of fuel plays a part, but I'm wondering about the high and low hp thresholds of max efficiency. Where does the law of diminishing returns show up? Great video.

[@AgentJayZ]

You are not considering all the variables, but only power output and efficiency. With only those two factors, there appears so far to be no limit. The bigger, the better.

Like you mentioned, post operation cooling for the bearings is a concern. All of the Solar turbines I work with have both AC and DC post lube pumps for that very reason.

martkt10 i've heard it can sometimes be attached to a steam turbine, the system i mean exhaust gas can be used to produce the steam needed ;)

[@TheDenzel2112]

Depends on the application they're used in, but often times the exhaust is directed into a HRSG (Heat recovery steam generator), which is basically a boiler. The HRSG can be unfired and just use the exhaust heat for steam generation or fired, where there are duct burners to add additional heat into the boiler for greater steam generation capacity. This steam can then be used in any number of industrial processes or used to run steam generator for additional electrical output.

You probably could use it for home power generation if you got your hands on one, but youd be better off using it to charge a battery bank rather than trying to run it full time since it would just idle the whole time, using tons of fuel.

In fact hydrogen is the ideal fuel for a gas turbine engine and is often used for testing prototype engines, with natural gas being a close runner up for that purpose. As I understand it, syngas is a mixture of carbon monoxide and hydrogen, similar to what we used to call "coal gas" or "town gas", back in the days before natural gas was discovered but we still used gas for heating and lighting. This is still made and used today, though usually for industrial chemical synthesis (hence the name syngas), though the ratio of carbon monoxide to hydrogen varies according to what is being produced from it. The energy content (aka heating value) of the syngas will be somewhere in between natural gas and pure hydrogen - it requires less oxygen for complete combustion than natural gas, but more than hydrogen alone.

Oh my all. Those speys outside are they all aircraft engines ? If so what from f4 s ? Can I have one please lol

[@MrShobar]

The old Boeing 502 gas turbine generated about 250 hp. Two reasonably fit men could lift it without a hoist.

[@joanygurl]

Caterpillar bought that design from Boeing, the only thing that remains from that program is the air to air heat exchanger which Solar utilized in the Mercury 50 program which was discontinued due to the high amount of nickel alloy used in it and the high cost of nickel.

Jay, what do you guys use that humongous torque wrenchs for? 30,000 lb/ft could tear a hole in the space-time continuum, I can't think of anything that needs that kind of torque.

[@AgentJayZ]

I posted a video of us using Big Blackie quite some time ago. Might be able to find it by searching my channel for Torque wrench. Otherwise I suggest watching all vids in chrono order.

[@makecba]

I've searched through your 440+ videos and couldn't find it. Any chance you have an index or something like that?

[@AgentJayZ]

Ok, from the foggy depths of my memory, I was able to stumble up on it. it's called Turbofan Parts Donor 3 . Please watch 1 & 2 also!

[@makecba]

AgentJayZ will definitely do. Thanks a lot and keep up the good work that this is one of the best channels on youtube :)

[@kyleharrison9518]

A quick question if I may: Is the AME program through Northern Lights College comparable in quality of instruction to BCIT? Hoping to study in Vernon. Thanks from Revelstoke. Ps: If I enjoy a future career in aircraft maintenance half as much as you seem to love your work I'll be a happy guy.

[@AgentJayZ]

AME covers the whole aircraft, and touches on the engine. The engine technician program is what I took. The two occupations don't really overlap. I never touch aircraft, and as a student, I regularly saw AME students in their engine module do things in very different ways than what we were instructed.

[@kyleharrison9518]

AgentJayZ cool, totally understand. Was just wondering if you’ve heard any industry good news/bad news about the programming at NLC vs BCIT. Thanks again for all the effort you put into the channel, it’s super cool.

[@wyrtwister4260]

Can the hot exhaust gas be used for supplemental heating ? Space heating in then winter or hot water heating year round ? I have seen a very few Solar gas turbines used for back up power generation at TelCo locations . Wyr God bless

[@joanygurl]

Yes, man gas turbines are used for Commercial Combined Power and Heat.

[@JimTheZombieHunter]

So, at 0:39 - Did you?? You got all excited about a piece of kit that YOU recognized, started nudging your GF/wife, "Ooh ooh that's a Q-36 illudium space modulator, look hun.." and get that strange cool level look where you wondered if they were calculating whether the marriage was worth the free car repairs?

[@michaelmooney3369]

I have seen some one cut the tip of their finger off just the way you said. they spun the compressor and didn't pull their finger away in time and........chomp. it was a Huey UH-1H US Army helicopter.

[@AgentJayZ]

I nearly lost my right hand to an RB211 compressor. I felt lucky and stupid at the same time.

[@beachboardfan9544]

+AgentJayZ that sounds like a great story for a video.

Industrial or aero?

The start of the video reminded me of Scarce's face reveal.

[@BillyNoMates1974]

Is that the smallest engine you have worked on AgentJayZ ? If not, what is the smallest turbine engine you have worked on ? Are smaller turbine engines harder to work on (space) ?

[@beachboardfan9544]

+BillyNoMates1974 Check out this T-58 videos/boat racing videos. Its probably the smallest axial flow engine I've seen on his channel.

[@brbroberts1]

"Nicely nicened." Hahahahaha

[@m.samaha4708]

I noticed that when you rotated the engine manually, the fans are in the front of the engine working together at low speed. After high, the fans took different speeds and different directions maybe. Does it true or just imaginations because it moving fast.

[@AgentJayZ]

+Mossad Ahmed samaha There are no fans in this engine.

[@YodaWhat]

That is a stroboscopic effect... a type of optical illusion caused by the camera frame rate vs objects moving in the frame. In 'Old West' movies, the smaller stagecoach wheels can sometimes be seen to rotate opposite to the large wheels, because of this effect. It depends upon how many spokes, or blades in this case, are on each wheel.

[@ellenorbjornsdottir1166]

AgentJayZ that is wrong. You have turbines which are driving your shaft and compressor, and when backdriven those are fans.

[@warpedweirdo]

Imagine this. You have a fan with a single blade. You turn on the power, it rotates at one revolution per second. You keep your eyes closed, except once per second when you quickly open then close them again. Do this perfectly, and that single blade will always be in the same position whenever your eyes flash open, so it appears to be stationary. Now you slightly increase the power to the fan so it speeds up just a little bit. Now, whenever you open your eyes, the blade is in a different position. It appears the blade is moving slowly in one direction. Decrease power down to a point a little below the original setting. Again, the blade is in a different position each time your eyes flash open, but the blade appears to be moving in the opposite direction. Next, imagine your fan has two banks of blades. The first bank has two blades. The second bank has 3. The assembly spins at one revolution per second. You open and close your eyes twice per second. Every time your eyes open, it appears the blades in bank one are stationary, even though they are swapping positions for every blink. But the three blades in bank two appear to be moving. So it looks like the two banks are moving at different speeds, even though they are aren't. Video cameras are like regular still cameras, except that they take a lot of pictures really fast.

Hy i need to do some overhauling for the fuel pump P/N 901580C1, MOOG MK1, i will appreciate any help, thanks in advance

[@AgentJayZ]

You'll need the overhaul manual. I also suggest taking apart a junk one, for practice, or maybe spare parts. Otherwise, I have no idea what it is. There is no master catalog of part numbers.

[@oberdanprosperini9010]

@@AgentJayZ Hu mate thanks for your response, i have to overhaul 50 of these Fuel pump, but we need tested at OEM Spec, I can not find any info on Moog or whitton about this pump. the turbine is a Solar Saturn 20. i only have the parts numbers of the FP. i know how to do the service, the issue is the report of the test acording to the OEM spec, also what a great videos you post amazing how you explain in details how the turbine works.

[@AgentJayZ]

Now that I know what engine it's from, I can ask a friend with Solar Saturn experience and resources. I'll let you know.

[@oberdanprosperini9010]

@@AgentJayZ Excellent i will really appreciate your help!! thanks a lot 😀

[@AgentJayZ]

I spoke to the owner of Tourbillon Turbine Services, and although he's got lots of Saturn experience, he informed me that the fuel pumps are part of the installation skid, and are not shipped to him for overhaul.

[@groznydyatlov4512]

What about the ones on the Abrams tank?

[@Flightstar]

Wondering what the fuel consumption would compare to a piston diesel at the same rated power output of 1000 HP.

[@AgentJayZ]

They are very similar. But piston engines are more economical at reduced power. Turbines are best used for constant, high load applications.

[@CaseyRedDragon]

Why the need for such a high torque?

[@shadowOrgon]

two questions, how much would a cut away model like that cost? you know...obviously for academic reasons..totally not to be the center piece of a livingroom *cough* ok more serious question, you said anything smaller then that sized engine starts to tank in fuel efficiency, why is that? is it because the parts and clearances get difficult to fine tune?

[@AgentJayZ]

If you have something we could use, we would trade for that. Once you get below 1 MW, diesel piston engines are cheaper to buy and easier to maintain... for about the same fuel economy.

[@TriniRogue]

This may be a very foolish question so pardon my ignorance, would a jet engine ( in any format ) be able to effectively run on CNG or propane? would the engine be down on power if it is, also would it simple be ineffective because the engine would burn through the fuel too quickly.

[@AgentJayZ]

Jet engines actually run better and have lower emissions on natural gas or propane than they do on liquid fuel. Almost all of the industrial engines we work on and test are installed to run on natural gas. These are not piston engines, so the amount of energy in the fuel is not important. If you need more heat, just burn more fuel. Easy.

[@DimMakTen]

They use gaseous propane when in the Test cell as ive seen in many videos. 😁
