Hey man, I did a decade with OPRA turbines, the founder of that company studied with the pioneer of the turbine, and inherited all his prototypes. The cantilevered design of his OP16 engine is basically exactly like a turbocharger. The main difference between a turbo and a gas turbine is the compressor ratio, you don't need such a big compressor. Is that why most of the rotor is exposed on this bench top item you're running? When Jan Mowill was well overdue for retirement, we helped get the company sold, and the perfect candidate was China - they have supply and emissions problems which need solving. The sheer reliability of delivering onsite power is not to be underestimated from an electrical engineering standpoint - and the chinese state has got significantly deep pockets to acquire a small to medium engineering company. It didn't go that great, and we dismantled the creative marketing department which had been consulting with the development teams about design concept and application engineering strategy. I also tipped off bladon turbines that their axial design was too complex, and they now make a very dainty 15kW radial turbine. This is great work you are doing, and I'l love to help. That machine you have made sounds horrendous, like a two stroke pizza bike being tortured - aha well that's the leaf blower you're using to start it... OK... if you're making net energy output you're winning... The energy lost by acoustically stressing the metal and propagating bending waves is an important domain to consider. We want smooth flow and smooth operation. The car turbocharger market is huge, so by mixing and matching rotors and housings, there is a great deal of room for winning solutions. A turbine is inefficient unless you also want the heat. As a supply of hot exhaust gas they are incredibly powerful, and should be considered a heater first and foremost. As an industrial engineer this is often overlooked, and a turbine can be used for thermal supply, very useful in food & drinks and for baking, as well as paper manufacturing and machine drying processes. The most suitable consideration which was being addressed by engineering at OPRA is preheat and premix of the fuel-air mixture. Much easier to get that flame to blue. A hydroxy gas flame is a pretty fierce temperature, and I suspect that's the secret to multi stage fuel injection - we can shape the combustion mixture and temperature gradient with electrolysis of H20. You could also try an axial compressor section combined with a rotor assembly off a car turbo. Always wondered if that would be a good idea, possibly making compressor made of something like carbon fiber rather than tool steel. The microturbine engineering clubs tend to use a compressor made out of plywood and carbon, which has a forgiving failure mode when over-strained at high revolutionary velocities, and turns into a sort of cellulose candy floss rather than exploding into shrapnel. The energy levels of a turbine overspeed accident are far, far more expensive than losing at roulette. Working out a test protocol for overspeed stress testing is a large part of the battle. More speed = more power.
@@mechusmanbutt Hopefully for safety reasons! Those blades were getting hot, could end badly for someone if ran for long periods, hope you ar still safe.
@@bamnasitis yes u r right. actually we noticed at the time of video shooting that turbine blades were a bit worned out. That turbocharger has already been abandoned. thanks for ur concern.
So using the Turbine for generating electricity and the exhaust gas can be used for heating purposes. A combined cycle heat and electricity too bad that English Wikipedia have not enough information but in German it is better described
Dr Usman your video inspired me to build my own version of the turbo turbine. After several iterations with varying levels of success. Ive recently settled on a design that i then incorporated into a smaller version of an aircraft APU. Im in the process of installing it into a Tesla model 3 where it will function as a range extender / battery tender. By using a modern vehicles turbocharger with variable pitch blades my goal is to allow the unit to function on a variety of fuels with my custom ECU / PCM / whatever nomenclature the units computer might be called lol, deciding where the energy generated will go, ie to the motors directly or into the batrery pack. So thank you for having made this video
@@zyphergaming3187 When sourcing on a limited budget, you must go where they are low cost, free, or you are actually paid to remove them. Where do turbo-charged cars eventually end up when they have completed their useful life cycle in Pakistan?
Lahore! My good friend Sheryar is from there! Hello from Canada. This is an interesting prototype, good use of pare parts. Do you have access to a machine shop though? Surely they could make something up for you, the plans must be available. An even easier design to make though would be a tesla turbine. It has very high power to weight ratio too. Bearings are an issue either way and it sounds like yours need some grease!
lol. you need to RUN. HOT to HOT.... exhaust to exhaust and connect the generator to the Compressor side. but still use the cool air for your oil radiator 🕉
What a shame all that money spent on College only complete one the most Elementary of projects. I built one of these out of my garage never went to college. There's those who desperately want to be smart and those who are born with it naturally. Bragging about your intelligence does not make you intelligent. Always remember this!
Yes exactly right, my mate Mr John Wallis has no college degree and built a number of turbines engines with great success, he just read a lot of books and lots of R&D.
I would love to see data on the generators performance running methane

propane fuel is expensive....the turbine has to be externally fired with fuel as biomass
or used motor oil
Running a bit warm?
Yes, pressure loss was high due to large tip clearence of turbine.

Are there a scientific article and/or technical documentation about your project?
The blower turns the shaft in opposite, use a vacuum on the exhaust end
accha kam kre rehe mujhe bas ic air flow ka theek nahi lag raha jo turbo ka hota tm electirc duct fan compreser use kr k hybird engine bana sakte easy
No lubrication system for the free turbine turbo bearings ? Haha

At the junk yard probably

Nice project, but I advise you to put safety goggles ,etc.
Exactly! That is an accident waiting to happen without safety equipment.

It will burn up from the heat
You need hearing protection and goggles!!!
