Steady State Performance

Variable geometry in key gas turbine components offers the advantage of either improving the internal performance of a component or of re-matching the engine cycle to alter the flow-temperature-pressure relationships. Future gas turbines are expected to use variable geometry components extensively if they are to overcome some of the problems encountered by present day engines at off-design conditions in order to give much more advanced performance. Greater attention is also being paid to the impact of installation losses on the performance of aircraft engines. A computer program called VATEMP, herein described, has been developed capable of simulating the steady-state performance of arbitrary gas turbines with or without variable geometry in almost any gas path component. Results obtained from the program led to the conclusion that variable geometry components have the potential to improve significantly the off-design performance of gas turbines.

Aimed at cantilever-type foil cylinder film seal system, finite element method analysis model was established to calculate the deformation of cantilever foil under the gas pressure based on the theory of plate bending. The paper proposed a method to solve fluid-solid interaction problems in cantilever-type foil cylinder film seal system based on the numerical analysis method of cylinder gas film seal. The calculation program using the finite element method to solve fluid-solid interaction problems was developed. Calculation simulation of the film mechanical properties and steady-state performance of sealing system was realized which improved the accuracy of the sealing system performance analysis and provided the basis for the multi-parameters matching design of sealing system. The impact of adding cantilever foil support structure to the steady-state performance of sealing system and the influence of flexible support parameters on the steady-state performance of the sealing system was calculated through the method.
