Answering like engineers.

Sorry guys, but you are all answering like engineers. Why has a 747 got four engines? Because the engineers haven't figured out where to put a fifth.

Wanderer asked the question - slightly skewed its true, 1300K is way too low, 300K is about room temperature;


Does anybody know the maximum temperatures inside modern jet engines?

I mean max temperatures inside the combustion chamber of the engine, not the EGT that pilots can read from their instruments as the EGT is already a somewhat cooler temperature further to the end of the engine.

I have read about temperatures exceeding the range of 1.300 K, as well as temperatures as high as 2.000 K with new modern cooling technics to cool the walls of the combustion chamber.
Are those possible numbers?

Thanks.

And Gas path answered it;

For the RB211-524 at take off power:
430psi 1400 deg C

And you know why he is asking, cos' its all to do with your volcanics, ain't it?

Anyone here know the rule of three?

To a Computer Geek, 3 is 2.9999999999999.

To an Accountant it is 2.843 plus 17.5% VAT

To a Physicist it is 3.00000 +/- 0.00001

And to an Engineer, it is 27 - just to be on the safe side.

Roger.
