Based on the aircraft mission profile and maneuver load envelope, a transformation correlation between aircraft maneuver loads and engine maneuver loads was proposed according to the aircraft motion states, enabling quantitative prediction of blade tip clearance during maneuver flight using a full-aircraft finite element model. The axial and circumferential distribution characteristics of tip clearance variations across different engine stages were calculated and analyzed, identifying critical engine sections. Results showed that under typical maneuver conditions, the most significant tip clearance variations occurred at the high-pressure turbine and low-pressure turbine, with changes of 0.22 mm and 0.20 mm, respectively. These variations were substantially smaller than those induced by thermal and centrifugal loads. The radial tip clearance change exhibited a linear relationship with linear acceleration and gyroscopic moment, demonstrating a quadratic relationship with additional centrifugal loads. Compared with counter-rotating dual-rotor systems, the influence of gyroscopic moments on the tip clearance of each stage in co-rotating dual-rotor systems was smaller.
