Knowledge sharing is the core of knowledge management.Sharing of design knowledge is a key to successful implement of knowledge management for aircraft engine design.It is helpful to improve the capability of learning

to increase the gross knowledge capital

to optimize the structure of knowledge capital

to enhance the capability of innovation of the design organization and to introduce the mechanism for knowledge sharing in the research institute of aircraft engine design.Consequently

this would enhance the design capability of aircraft engine design organization.The knowledge management flow for aircraft engine design were drawn out with an emphasis on correlation matter of knowledge sharing

which include knowledge transfer

obstacle to implement knowledge sharing

implement strategy and key technology of knowledge sharing.
