Abstract: A fuel injector comprises a fuel feed arm and a fuel injector head and the fuel injector head has a fuel passage. The fuel feed arm has a fuel supply passage in fluid communication with the fuel passage in the fuel injector head. A first light guide extends through the fuel feed arm and has a distal end arranged to direct light into the fuel passage in the fuel injector head. A light source is arranged to supply light into a proximal end of the first light guide. A second light guide extends through the fuel feed arm and has a distal end arranged to receive transmitted light in the fuel passage in the fuel injector head and a light receiver is arranged to collect light at a proximal end of the second light guide.

Abstract: A combustion chamber arrangement has an annular outer wall and an annular inner wall having an upstream row of tiles and a downstream row of tiles. The outer wall has a concave bend which is less than 175°. The downstream end of the upstream tiles and the upstream end of the downstream tiles are adjacent the concave bend. The downstream ends of the upstream tiles are spaced at a greater distance from the inner surface of the annular outer wall than the upstream end of the downstream tiles. The upstream tiles have curved lips extending in a downstream direction which overlap but are spaced radially from the upstream ends of the downstream tiles. The outer wall has a row of apertures to direct coolant onto the outer surfaces of the curved lips and the upstream tiles has a row of apertures extending to the inner surfaces of the curved lips.
