Homebuilt Gas Turbine Engine For Helicopter Propulsion. by Pakingzzz(m): 12:47pm On Jan 10, 2014
After all said and done... I have decided to embark on my second project.. It is a gas turbine engine...
I can try my hands on building a full scale helicopter that can carry humans and cargo.
But at the moment,i have no feasible propulsion system for that kind of big helicopter.. I'm well aware of the fact that,if i am to build a full scale helicopter. I would have to drop electric power and begin using fuel power. Hence the reason i decided to try my hands on gas turbine mechanics.

Here,i am going to explain how a gas turbine works,and how it gets its power.
Just take a little glance at the picture below. It is a schematic diagram of a gas turbine.

Re: Homebuilt Gas Turbine Engine For Helicopter Propulsion. by Pakingzzz(m): 1:17pm On Jan 10, 2014
A gas turbine falls in the jet engine family. However,a jet engine uses it's exhaust gases for propulsion. But a gas turbine uses it's exhaust gas to rotate a fan. This fan is connected to a shaft. When the fan rotates,it rotates with shaft. This shaft,after going through some enormous reduction gearing system,is used to rotate the rotor blades of the helicopter(if used to power a helicopter).

Gas turbine works by sucking in air with the help of a large fan(impeller). This impeller compresses the air,and pushes the air into section called a "diffuser"(not shown in the diagram above),after passing through the diffuser,the air enters the combustion chamber,where it is mixed with fuel and burned to produce hot exhaust gas which is used to get the output shaft rotating...
What the diffuser does is: as the air passes through it enroute to the combustion chamber, it causes the air to lose velocity and gain an increase in pressure.. The major efficiencies of gas turbine engines lies in their operating pressures.
The higher the pressure,the higher the power output.

I'm following & actively participating in this project all the way.
@ Pakingzzz, nice work with the helicopter. You really inspired me.

hi all,

am happy a fellow Nigerian is dreaming on building a gas turbine engine.

Am to encourage you and also let you know that its very possible to build a running engine with less troubles.

am Chuks Anthony From Oduma Aninnri L.G.A, Enugu State.

am a Jet lover too, with my little experience I have built few gas turbine but not all that worked.

but believe it or not i now have a working gas turbine engine I built from scratch.

the required thrust is not achieved so am not too happy yet.

my new gas turbine am designing now for my helicopter project will cure all my heart breaks, its going to be large.

below are few pics of my currents woring gas turbine engine....

More gas to your turbine brother, It is this kind of projects I want to see. If not the recession that is biting hard i would have love to support financially

yeah,

always on my plan of changing parts when they dont fit in well.

you know me from somewere?

thanks,

the noise of my gas turbine is just blocking my ears from hearing the sound of our countries recession

Nice work you are doing here.. I can see a great degree of success..
Just keep it going man.
Thrust shouldn't be a problem now. Remember you are going to be using your gas turbine to drive the shaft of your helicopter..
You should focus on adding another turbine blade. So you can use the power of the second turbine as your output shaft. But remember that you must use a reduction gear to reduce the rotation of the output shaft considerable, so you will have enough torque available for turning the main blade and the tail blade.
Goodluck

bros drop me ur accnt number... a little is somthing.


just make certain u be on the air ........... i wana cee a nigerian independently be on the air(all locally made)

lets start donating

thanks pakingzzz,
my engine is made to produce ~40-45kg of thrust and that must be considered before choosing a free power turbine for the engine if am going to use it, too little flow and throat area will couse the engine to over heat and when too big will waste the exhause power. plus the gear box gear ratio will depend on the free stage max rpm and HP.
it can actually give me that thrust but at the expence of the exhaust temp that might result in melting my turbine blade.
so am currently getting ride of any vibration and frictions in the shaft tunnel and the turbine-to-shroud tolerance that might be coursing restrictions to the rotor,
I believe thats where I should start from.


though I dont intend using that for my helicopter project but I still think I need to make sure it works exactly as the theory says it should,

I would have loved to start my own thread on naira land but that will be pointless since the project have been completed,
but I will surely do that when the helicopter build starts, and ofcouse it will start with the engine build and ends with a successful coaxial helicoper and I will share every details.
yes, coaxial that means no tail rotor, so am going to need high torque and horsepower to do that.
its going to feature a twin gas turbine engine.

thanks

Re: Homebuilt Gas Turbine Engine For Helicopter Propulsion. by cj4humanity: 8:56am On May 14, 2017
I so much love turbines and the calculations involved, though boring. My advice is this bro make good research on materials you use for the body parts because they play very important role in engines that's why most of fine projects in my school easily become scrap even when they are tested OK, the question is, can they survive the test of time? More so, try modelling first before carrying out a big realistic project. And form a team, two heads they say are better than one, unless you are very good at working alone. I wish you all the best. I strongly believe that if white people can, we surely can.
