摘要： A hybrid variable area fuel injector is provided. The fuel injector includes a main body portion and a head portion carried by the main body portion. The fuel injector defines a fixed area port provided by the head portion for use during low flow conditions. The fuel injector defines a variable area port for use during high flow conditions. The variable area port is provided between the main body portion and the head portion. The area of the variable area port is adjustable due to the position of the head portion relative to the main body portion. The fuel injector also includes a shield portion surrounding at least a portion of the head portion. The shield portion reduces the amount of cross-flow that impinges on the head portion to reduce heat transfer to the head portion.

摘要： A fuel injector and turbine engine incorporating the fuel injector are provided. The fuel injector includes an active cooling system that insulates fuel flowing through the fuel injector from heat energy within the turbine engine. The cooling system includes a cooling air passage that includes an inlet and an outlet. The inlet and outlet are in fluid communication with the interior of an engine case of the turbine engine. The inlet is at a higher air pressure location than the outlet such that air is siphoned through the cooling air passage. A portion of the cooling air passage includes a heat exchanger for extracting heat energy from the cooling air. The cooling air passes through the fuel injector after it has passed through the heat exchanger. The heat exchanger is positioned external to the engine case and in thermal communication with the ambient.

摘要： A fuel injector having a body with a bore, which defines a fuel manifold. The injector also has a variable-area injector arrangement having a pintle with a conical head and a pintle spring connected to the body. The pintle spring urges a tip of the pintle to seal against an exit orifice of the body, such that application of pressurized fuel within the body causes the pintle to move. Above some threshold pressure, the pressurized fuel causes the conical head to move out of contact with the exit orifice of the body. This, in turn, provides a corresponding variable area for passage of the pressurized fuel through the exit orifice about the conical head of the pintle. The injector further includes a swirler configured to create a swirling action in the flow of pressurized fuel through the fuel manifold, wherein the manifold is upstream of the exit orifice.

摘要： A fuel injector is provided. The fuel injector includes an injector support and a heat shield coupled to the injector support. The heat shield only interacts with the injector support by way of contacts such as point contacts, line contacts or surface contacts. Further, the heat shield includes a body portion, a radially extending flared end portion and a radially directed shoulder interposed between the body portion and the flared end portion. The shoulder portion acts as a flexure point that flexes and absorbs thermal expansion of the heat shield.
