摘要： A fuel injector device (1) comprises a body, said body comprising a leading edge (11) and a trailing edge (12) and defining a streamwise direction (3) from the leading edge to the trailing edge. The fuel injector device body further comprises a first surface (101) and a second surface (102) opposite the first surface, each of said surfaces extending between and comprising the leading edge (11) and the trailing edge (12), and said surfaces conjoining each other at the leading edge and the trailing edge. The trailing edge (12), when seen in the streamwise direction, undulates along a trailing edge mean line (13) and, along its extent, deviates in opposite directions from said mean line and further comprises at least one inflection point (14) along its extent. The fuel injector device further comprises at least one first internal fuel supply means and at least one first fuel discharge duct fluidly connecting the at least one first internal fuel supply means with a first fuel discharge means (15) opening out to the exterior of the injector device, wherein at least one first fuel discharge duct terminates at a first fuel discharge means arranged at the trailing edge. At least one first fuel discharge means (15) is arranged at the trailing edge (12) between two trailing edge inflection points (14).

摘要： Disclosed is an aerodynamically shaped body (1) for use in a hot fluid flow. The body (1) extends along a camber line (100) from a leading edge (11) to a trailing edge (12). The body comprises at least one coolant supply plenum (101) provided inside the body, wherein the coolant supply plenum is delimited by a body wall, wherein the body wall extends from a first side of the camber line (100) to a second side of the camber line (100) and extends over the leading edge (11), thereby providing a leading edge wall section. The wall further comprises an inner surface facing the coolant supply plenum (101) and an outer surface. At least one first leading edge cooling duct (20) extends from the inner surface to the outer surface and is in fluid communication with the coolant supply plenum (101) through an inlet opening (21) and opens out onto the outer surface through a discharge opening (22). The inlet opening (21) is provided on a first side of the camber line (100), the discharge opening (22) is provided on a second side of the camber line (100), and the leading edge cooling duct (20) is provided inside the wall and extending inside the wall from the first side of the camber line (100) to the second side of the camber line (100) and thereby crossing the camber line (100,) in a leading edge (11) region.
