Abstract
A method of manufacturing an annular wall () of a combustion chamber () comprises depositing layers of a metal sequentially one upon the other to form layers of a spiral wall () of the combustion chamber (). Each layer of metal is deposited in a spiral pathway (). The ends (E, E) of the spiral wall () of the combustion chamber () are joined together to form the annular wall () of the combustion chamber (). The ends (E, E) of the spiral wall () of the combustion chamber () are at the opposite ends of the spiral pathway ().
