Liquid atomizing devices

Abstract

Abstract The invention relates to liquid atomizing devices, particularly intended for use in the burners of gas turbine engines. Such a device comprises a tubular body, through which, in use, air flows to a swirler formed by vanes at the downstream end of the body. The body is mounted on a support which contains a fluid passage communicating with a similar passage within the body. The fluid passage within the body is defined by a tubular member within the body and the passage may lie either within this member or between the member and the body wall. The fluid passage within the body terminates in an end wall within which, or adjacent to which, are a plurality of holes through which fluid is ejected downstream of the swirler and in a direction generally transverse to the airflow. The transverse direction of fluid ejection is achieved either by the directions of the holes themselves or by directing the fluid against a projection of the end wall or of the body. The tubular member may form part of the body or may conveniently be in the form of a cast insert. Preferably there are the same number of holes and vanes, and each hole is adjacent the root of an associated blade at the trailing edge thereof.
