Jet engine.

Do you talk about a "single-head" or "double-head" combustion chamber on a jet engine?

Cheers

actually a jet engine is just a fan, a compressor, combustion chamber and a turbine. the air in the combustion chamber is supplied by the compressor, so there is no head.

Term used are, among others: annular, can-annular and cans.

Thanks Piltdown Man could you expand on this for me? :)

cosworth - may I recommend the excellent 'google'? Type 'annular combustion' into the search box.
