Abstract:
Certain transient events such as hard landings, high g-rate turns, thermal conditions, and high turbulence may cause rubbing events inside the gas turbine that result from the flexure of the engine shafts. In order to prevent permanent damage to the engine or operational interference, brush seals are used such that the tips of the stator blades and the tips of the respective opposing annular brush seals, and the tips of the rotor blades and the tips of the respective opposing annular brush seals define substantial radial clearances that provide gaps that remain open under all regular and normal operating conditions of the gas engine.
