Abstract
The article considers changes of liquid rocket engine turbopump turbine seal clearance. During operation. significant change in clearance occurs in comparison with the clearance between rotor and stator seal elements during assembly. The current approach does not involve taking into account the effect of turbine seal clearance changing to the unit parameters and characteristics during design. The report presents an approach to the analysis of seal clearance change, depending by turbopump and engine operating mode.
