Abstract
This paper mainly focus on the research of the active tip clearance control scheme for a high pressure turbine on aircraft engine. A brief interpretation of this model is illustrated. Then a rum-time based engine control model (including steady and transient control) is added to the high pressure turbine model, the high pressure tip clearance can be simulated upon the rebuilt model. The High pressure turbine tip clearance control method is realized by bleeding the cool air from the fan to the case shroud, the objective of this paper is to derive the reasonable control plan for the Active tip clearance.
