Discussion on the best fuel type.

[Bhuvan Aerospace]

Sir, after igniting through the outlet of the turbine wheel, Do I have stop the engine to catch the flame? Or simply ignite and do nothing and allow the engine to run? And according to you, which best , to keep the igniter inside the combustion chamber or ignite it from the outlet?

[richardm]

How do you think you ll get the engine running if you shut it down right after ignition ?

[Bhuvan Aerospace]

I was telling to minimise the airflow.

[racket]

You get the engine rotating with the blower, turn on the propane and remove the blower whilst applying the ignition to the turbo outlet , as the RPM decay the fuel/air mix will reach an ignitable level and the gas will ignite and go back inside , reapply the blower , sealed against the comp housing inlet , and increase fuel supply as the RPM increase

As expected this went from supersonic flight 100kg cheapest engine in the world, to an old turbo with a tin combustor and a lighter?! I mean at 15 years old it’s still a good effort but you should be careful not to injure yourself, and to be honest about expectations.

[Bhuvan Aerospace]

Thank you so much John Sir. I am gonna try it now only. I will link a video or tell you the results!!

Hello Slittlewing (Scott) sir!! It is just the prototype engine which is being used to enhance our engineering skills. Then I will convert this engine to Turboshaft engine. The main engine will have the ability to push the aeroplane to Supersonic Speeds of over Mach 1. The expected date of completion will be 2030. Thank you sir for guiding me and helping me and telling me to maintain my health and avoid injuries. And I believe that I can achieve it. Still, This sucking small prototype engine will be India's first Micro Turboshaft Engine!!

2030? Building your own gas turbine and airplane that will go supersonic speeds isnt that hard, you should be able to complete this within a few months

What do you mean y turbo shaft engine? This category of engines are used on helicopters boats or some other pieces of machinery There are also turboprop engines and turbo fan.
Neither will get a plane to go supersonic.
Get realistic about your project.

[Bhuvan Aerospace]

After the completion of the prototype engine, what will I do with it? It has only 3 kgs of thrust but the turbocharger with the combustion chamber weighs 5 kgs itself only. So I will convert it to turboshaft engine to generate electricity or make a small car.

Hello Cebaero sir, can you please advise something about this?

[dieselworks]

You should use nuclear fission to provide the heating for your engine rather than burning fuel. With chemical fuels, liquid or gaseous, you have to deal with flames, combustion instability, ignition... it's a real hassle. Get a bunch of uranium and assemble the reactor. Flow air from the compressor over the reactor core before piping it into the turbine. They did it in the 1950s, you can do it.

[Bhuvan Aerospace]

Sir where to get uranium and thorium?

[Bhuvan Aerospace]

Sir, Can I make that sure? If yes, then I will make nuclear fission only. Tell me the process sir.

[Bhuvan Aerospace]

My turbojet engine is nearly ready, will test it tomorrow.
