More Information
Summary:The invention belongs to the technical field of aeronautical manufacturing design, and provides an aero-engine bearing cavity ventilation design method which comprises the following steps: connecting a temperature anomaly acquisition point and a lubricating oil flow anomaly acquisition point nearby to obtain a connecting line; the connecting line between the collection points is segmented by combining the ratio of the temperature abnormal degree to the lubricating oil flow abnormal degree between the two collection points, and the position coordinates of the segmentation points are obtained, so that the ventilation opening is designed according to the position coordinates of the segmentation points. The ventilation opening can simultaneously solve the problem of temperature abnormity or lubricating oil flowing abnormity at two positions, and position coordinates needing to be designed by the ventilation opening are balanced according to the temperature abnormity degree and the lubricating oil flowing abnormit
