In order to overcome the difficulties in advanced aero-engine design, such as complex coupling relations and serious conflicts between different disciplines, the research, development and application of key technologies of MDO have been carried out in three phases: part design, component design and whole engine preliminary design.

Control method of time on wing for civil aeroengine;

Fault diagnosis and adaptive reconfiguration control for sensors in aeroengine based on improved least squares support vector;

Research on detection system of aeroengine large wear particle based on microimage;

Establishment of Aero-engine s Model Based on SMI Identification Method;

Combination forecasting model of aero-engine maintenance costs based on statistic rough sets theory;

Research on Aerodynamic Detection of Aero-engine Blade;

Complicated nonlinear systems such as aircraft engines.

The technology of surface modification was an efficient way to increase fatigue life of the mainshaft bearing of the aircraft engines.

Considering the geometric features of the air cooled turbine blades of the aircraft engines, the methods to sort the features in the parametric modeling of the blades were advanced.
