Parametric design of turbine blades based on feature modeling;

Research on Fatigue Life of Large Gas Turbine Blades;

The single crystal Ni-base superalloys were widely used for manufacturing advance gas turbine blades,but the ignored weakness of these alloys to date is that the extent of primary creep at intermediate temperature is much higher than that at high temperature.

Error Analysis on Turbine Blade;

Displacement transfer with the mesh deformation method in multidisciplinary optimization of turbine blades;

Turbine blade design and optimization based on the combination means of parametric-Bezier curve;

Research and Application of Parting Design for Turbo Blade Mould with the Case- based Reasoning (CBR);

An integration system is set up to meet the need for information integration in the process of mold design and manufacture and detection of aero-engine turbo blade by investment casting.

Seven stageⅠturbo blades fractured during working time of an engine.

Precise reconstruction technology of curved surface of turbine vane;

The third class turbine vanes of some engine have fractured three times successively.

Therefore, eliminating these grain boundries can improve the resistance of turbine vane cracks, based on which directly solidification was developed.

Study of the influence of blade edge modification of low-pressure two staged turbine on the turbine efficiency;

Launch of on-board weapons makes it difficult to do two things well:(l)simulation of transient process of trubojct engine and(2)the determination of deviation of combustion efficiency and turbine efficiency from those given by standard characteristic maps.
