Incredible! Now it's like any turbo car, just turn up the boost till it pops. Stiffer spring, boost controller or straight to reference to the top. I'm surprised one little gate kept it at 5 psi after seeing the way the other gate did nothing.
Thrust. Stable boost. What's more to ask for? Bobby McBoost: - MOORE BOOST!!! Surprisingly cold AB. Sounds right to feed the fire more of the air from the cold side. I wonder if a little water wouldn't do some nice things. In the current setup I'd go for adding a little to the flow going to the fire, after the "Y-pipe". To much would put the fire out, to little would hav no effect, but the right amount could take som of the excess heat from the fire and turn the water reacting with carbon from the wood into syngas (H2 and CO) , giving it more easy fuel to burn in the AB. Playing the water in tank game safely is advised tho, since water-steam expansion could make a mayor explosion in an unlikely worst case scenario. A WIN More thrust than the channel Survant James and their Turbofurnace project, even tho the try a much fancier setup. Good job
Incredible!!! You probably need a convergent-divergent nozzle, but I'm not skilled enogh in pressure ratios between nozzle and a turbine itself, I only did nozzles for solid rockets where there's easy to calculate pressure
The wastegate definitely makes it. From what I've seen of these things online, they normally just spike the boost and run away, but your usage of the wastegate seems to be keeping everything under control. I agree the wastegate isn't perfectly suited, but it's what you had available, it works, and nothing melted to buggery. Keep up the good work 👍
This is great. It’s not easy to make a wood fired turbine that works well. I made one about 20 years ago with an IHI RHB3 I tried to make a bypass system to control the fuel delivery output but it was kind of unstable. When I got up to about 15 psi the whole thing was glowing red and we all ran away from it thinking it might explode, so I understand why you guys don’t wanna ride in this boat. I like your wastegate solution.
Hey Bobby, huge fan of what you're doing. It's fun, scrappy, and surprisingly educational. I have no intention of being a backseat captain; however, I would like to bring to your attention that metal spinning at high RPM likes to turn into deadly shrapnel. Perhaps a flak blanket around the spinny bits might raise your safety factor in the event of catastrophic failure significantly. I only say this because I look forward to your crazy antics for years to come. Experimental rigs and safety often don't go hand in hand, but you can certainly reduce risk where possible, yeah?
Excellent way to control boost on this setup! I was thinking about what you have done and have a couple of ideas. Maybe try piping the wastegate to the turbine inlet on the tank? I'm thinking you could run it higher up and keep it cooler?! Then maybe also figure out a way to control the wastegate to vary the throttle/boost!
Wonderful! Wish we had gone this route instead of wheels. Makes for a much better demo. Love the wastegate to regulate pressure. Turbine inlet temps still look absolutely massive though!
Nice, Now that it's in a a boat you should have the options to upgrade to a water cooled turbo as well as cooling down the oil. maybe even a R/C throttle body on the intake even a carbureted Venturi on the afterburner. Looks like there may be enough time left in turbskiejet for just maybe one more full send lunar for da Frankenfloat aka Frankenfloat--ter..... you do what you do and I can't wait to see her back on the Billabong with her hot wet and ready to blow.
Would you be able to use RC Servos and a controller for operating valves and whatnot? Also maybe a little rudder in case it starts careening towards you!
THIS IS AMAZING! YOU SHOULD TOTALLY PUT THIS ON A CAR MATE! OR EVEN BETTER AN ULTRALIGHT!! This totally reminds me of the older Varks or 707s, good ol' days with the howl and smoke!
I don't know anything about anything, but.... Next I'd try a smaller pipe for the waste gate feed to restrict it slightly. It like it never really spooled up like the other videos. And maybe a longer pipe off the back of the cone too, a longer barrel on a gun creates more velocity. cant hurt. Nice work though, keep feeding that crazy creativity!
this. just get a RC servo, that should do the trick. might as well get some steering while you're at it and you've got the most badass RC toy in existence
Shrink it down a bit and use coal for the fire then stick a second turbo on the exhaust of the first and you have a boost box that will supply full boost to anything it's hooked to. No need for anti lag it's full boost at idle from here on out!
Top job. Should try turning the tank side ways and hanging off the back so it's in the water, keep the inlet cool acting like a intercooler and would get the exhaust lower to the water line to help improve speed. Would also keep it further away so the more mental could actually be in the boat. Also injector nozzle and pump some diesel into the afterburner for full reheat.
Very nice. I wonder if you direct the thrust into the water if it will go faster. You could do a small mechanical boost ctroller. Then you could set the boost and prevent the turbo from blowing up. For the afterburner you might need a flameholder. Just screw in a few bolts from the outside and it should be fine
You can probably get a good thrust boost if you can use bypass air. Look up jet engine bypass ratio. I would think you might be able to if you drive an even bigger second turbo in front of the first.
Bleeding the compressor to the exhaust like that is an interesting way to create a turbofan without a separate HP and LP stage. Trying to go to a traditional turbofan setup (go back to small turbo for the core, hook the big one to the exhaust of the small one and use its exhaust solely for thrust) would probably melt your combustor. Or maybe the back pressure from the big turbo would keep the little one in check?
Far more entertaining than NASCAR. I see competitions with these turbo barrels in the future, blowing them up would rival Aussie burnout shows. Could even have different fuel classes, wood, coal, waste oil...
You could put a ball valve and a t on the boost side of the turbo to use as a boost bleed. It should work better for a throttle and won't blow so much oil into the intake charge. I'd assume the high vacuum is playing havoc on the oil seals.
I'm no turbojet mechanic, but seeing as you've got a whole pile of water and a pile of excess heat, you might be able to amp up the thrust with some water injection.
No, by adding water you would cool the exhaust but produce a whole lot of steam. That stream means a whole lot more volume. IIRC this was done on planes to get extra thrust, there was even an accident whete someone put fuel in the water tank. Kind of a weird hybrid combustion/steam engine cycle.
Now it's air cooled too!! You guys should make the exhaust go down into the water, since the water will create more resistance for the air to move it should make for more thrust because the air cannot go backwards and must go out. Compared to blowing straight into the atmosphere where the idle air around just gets blown out of the way almost immediately creating little to no thrust. Although it may not be very good for the water but at least it's not an actual engines exhaust in the water, just the fire exhausting into it. Most of the contamination is going to be charcoal which isn't bad for water it kind of purifies it.
A freaking wood gas turbo jet with afterburn lolol epic You should inject a touch of that lube oil into your afterburn nozzle with your added bypass air, that would really wake it up.
Needs a tighter spring! Leave it as the larger gate. I'm guessing it was a 5 or 6psi spring based on the boost it held at. Just put one in that holds 8 or 9psi. Should be fun!
I wonder how much horsepower comes out of that turbo If you could somehow weld a shaft on it while maintaining balance. Effectively turning it into a turbo shaft engine. The possibilities are endless, stick a pully on it and run a belt to a prop, or a wood powered jet generator
I cannot wait to see what you mechanically figure out. Then how you throw some wings on it and see how she really moves when you angle the thrust. Remotely.. might be difficult, so throw in a fire wall haha
wonder if you could make it work with a propeller attatched to the exhaust turbine or some sort of drive drive chain using the spinning turbine as a drive
This is absolutely brilliant 👌😂 I will add that the turbo could have been more effective but I think you need to open up the size of the pipe on the burner to the turbo look how hot it is.. that's a big restriction on the exhaust flow into the turbine Do this again for sure looked so fun
should try use a second bigger turbo exhaust turbine and housing spinning from the exhaust adapting it to a prop-shaft with a gearbox reduction. spin a jet-boat turbo pump.
I keep telling people that jet engines are the most versatile power makers on the planet. If you can burn fuel and make a heat source for continuous ignition, you can power a jet engine. After the big power outage a few years back that took out the whole state, I told the family 'never again' and now have a fleet of backup turbojets that can cycle off of waste oil, coal, wood, and liquid fuel is easy.
как я понял запаса дров хватило на 5 минут работы турбины а это 40 литров или 15 килограмм древесины -если это так то ответь так ли это или у тебя был другой вес дерева
This is brilliant, I reckon its time for a second channel "Bobby Mcboost marine and heating"
This is so epic. So glad that the wastegate worked. Awesome that it's actually somewhat controlled so it's not gonna just run away
The 30psi video was totally nuts
The boat camera angle with the boost gauge is 👌🏼👌🏼
LOVVVVEEEE the 46 aerosol cans on the welding bench.

Instead of water I'd maybe add a liquid or even gas accelerant, like a REALLY volatile/flammable one. Nitrous oxide would be interesting.

Fantastic.
Wastegate worked like a charm. Needs further testing
Could it heat a forge or a foundry ? You need to stout all that up and make it less...lethal. nice work
Could do a remote controlled rudder. Could even use a remote control linear actuator
this. just get a RC servo, that should do the trick. might as well get some steering while you're at it and you've got the most badass RC toy in existence
Maybe use a second channel for a boost controller to control thrust.
I did have this thought! Just don't know where to look for a decent strength servo/motor and the control gear..
@@BobbyMcBoost Mythbusters set up a remote control car using a motor to turn steering wheel.
The control gear to talk from remote to servos would be my challenge..🧐

I think you should put a humongous velocity stack on the intake, and see what kind of performance increase you get! Cool stuff.
I can give you an answer. If its done properly a little over 5%
You could put a ball valve and a t on the boost side of the turbo to use as a boost bleed. It should work better for a throttle and won't blow so much oil into the intake charge. I'd assume the high vacuum is playing havoc on the oil seals.

Awesome guys, now you need like a 4 inch ball valve on the tank so you can fill and start it, then quickly and safely shut it to build pressure
After you get this dialed in, I think there is no shame in injecting waste oil into the afterburner. hehe
Could you inject fuel into the afterburner? Turn some water into steam for additional thrust? Extend turbo life by filtering out combustion debris?
I'm no turbojet mechanic, but seeing as you've got a whole pile of water and a pile of excess heat, you might be able to amp up the thrust with some water injection.
How exactly does water injection help? Wouldn't that lower exhaust temps which would also lower thrust?

How are you oiling the turbo bearings? And a waste gate dumps pressure away from the turbo .🤔
Hey why don't you try adding a gear system to the turbo in order to extract some shaft power so that you can transmit it to a propeller.?
Crazy, I thought when I first saw this, but with the current gas prices you might be on to something.
