Abstract: A gas turbine engine carburetor includes a fuel injector and a cooperating air swirler for injecting fuel and air into a combustor. The fuel injector includes a hollow body joined to a supporting stem for receiving fuel therein for flow through an injector tip slidingly mounted to the injector body for movement relative thereto. The air swirler surrounds the injector tip and is spaced form the injector body to define an air inlet, and is spaced from the injector tip to define an air outlet. A spring operatively engages the injector body and the injector tip and is preloaded for biasing the injector tip to an initial position. The spring is sized so that increasing pressure of the fuel in the injector body further loads the spring for moving the injector tip from the initial position to a displaced position, with movement of the injector tip modulating airflow through the swirler for in-turn modulating the ratio of discharged fuel and air.

Abstract: In a control system for controlling at least one variable (TITm) of a process, the at least one variable (TITm) being calculated from a multiplicity of measured process variables (TATm, pCm), the measured process variables (TATm, pCm) in each case being measured via associated measuring sections (18, 19), the transfer functions (G2(s), G1(s)) of which have a different time response, an improvement in particular during transient actions is achieved in that, to avoid instability, correction means (21) which equalize the different time responses of the individual measuring sections (18, 19) are provided.
