Very Small Exhaust Hole

[Bhuvan Aerospace]

I have taken the decision of making my own R.C turbine engine. They are very lightweight and produce more thrust compared to turbocharger jet engine. Can anyone tell me about the maths and designs for making this engine?

I have joined gtba sir. But sir, if I use 120 mm inducer in my R.C turbine engine, can I get 30-40 kg thrust?

[racket]

120 mm inducer = >100 kgs of thrust

[Bhuvan Aerospace]

Wow sir!!

[Bhuvan Aerospace]

That’s about 1 kN thrust sir!!

Scott has achieved 100kgs of thrust using a 110 mm inducer , see video at bottom of this page........... jetandturbineowners.proboards.com/thread/1409/scottscrazybuilds-jet-kart?page=16

[Bhuvan Aerospace]

But sir, is it harder to make big one or small one?

[Bhuvan Aerospace]

Sir, can my plane get to 700kmh with this 100 kg thrust engine?

If you are unable to estimate the top speed of an aircraft with an assumed thrust and coefficient of drag using the normal drag equation then you likely do not have the skills to complete such a project. It will also be expensive (multiple thousand USD) to build a 1kN engine. And it will not be airworthy/certified.

[Bhuvan Aerospace]

Our community has the science experts. No worries sir, we are Indians and we can complete $1000 project in $500 also. There are also Australians in our community.

I got 35 N drag force sir with rectangular wings ( just for calculation) with chord of 30cm and length of 60 cm and takeoff speed of 80 m/s

You should buy a Chinese rc jet engine. They are about 1000-2000usd, lightweight, compatible with RC electronics. You will not be able to produce one for less money yourself.
