  • To improve the blade-tip radial running clearance(BTRRC) design of aeroengine high pressure turbine(HPT), the probabilistic analysis of BTRRC was implemented based on deterministic analysis through considering the heat and mechanical loads of objects (disk, blade and casing) and selecting random variables legitimately. The variation of BTRRC and the radial deformations of objects with time were gained and the minimum clearance at t=180 s was regarded as the probabilistic analysis point through the deterministic analysis. In addition, the probabilistic distribution features and failure numbers, failure probabilities and reliabilities under different static clearance δ predetermined were obtained besides the major factors impacting on the deformations and BTRRC through the probabilistic analyses. The results show that δ=1.95 mm is advisable to select as an effective reference for the control and design of BTRRC for satisfying the aeroengine design and engineering.
