| Aiming at the problem of setting balance rotational speed in the balance process planning of aeroengine fan/booster rotor，
by considering the factors such as clearance of blade dovetail，the performance of balancing machine and the rotor aerodynamic torque ，the calculation model of balance rotational speed of fan/booster rotor was constructed. The parameters of structure and performance of an en?gine fan / booster rotor were brought into the model，and the rotor balance rotational speed was calculated and compared with that of similar foreign rotors balance rotational speed. The results show that the rotor balance rotational speed calculated by the model is 685 r / min，which is basically consistent with that of similar foreign rotors balance rotational speed，and meets the actual balance requirements of this type of fan / booster rotor. The balance rotational speed calculation model has been successfully applied to the design and process docu?
ments of fan / booster rotor balance，which improves the design ability of fan / booster rotor balance process. |
