Need help with combustion chamber design

[madpatty]

Hi All,

This is regarding my almost first(last one failed) turbojet engine in which i will be using a Holset Hx35 turbocharger with 54 mm inducer diameter....

I have got general queries about the combustion chamber design...

I am too afraid of fuel burning in the turbine that i am ready to build the combustion Chamber AS LARGE AS POSSIBLE....?

About the Flametube can i use 161.5 mm ID steel pipe???

What are the possible consequences of using a larger diameter flame-tube???
