Abstract
Cooling of engine walls with fuel, wherein the walls have a structure which has an inner wall, to which hot gas is admitted during the operation, a colder outer wall, as well as a plurality of webs which connect the walls and divide the hollow space present there into a plurality of cooling ducts. The fuel is introduced in the cold state into the wall structure, is delivered through the cooling ducts while absorbing heat via the inner wall, and is subsequently used to generate thrust. A hot fluid flow taken from the engine is admitted during the operation from the outside to the 'cold' outer wall of the wall structure, through which fuel flows, and this 'cold' outer wall thermally expands as a result, or its thermal contraction is reduced.
