Abstract:The inheritance，development and innovation of technological knowledge and its integration with the information system are the key problems that restrict aviation manufacturing enterprises，especially those oriented to multivariety and fastupgrading of aviation products.Concerning the present situation and problems of technological knowledge management in aviation manufacturing enterprises，the system building for technological knowledge management is discussed under the guiding ideology of knowledge engineering.Through knowledge collection and arrangement，the tacit technological knowledge is turned into the explicit one，which is inherited and shared through the knowledge engineering platform.Therefore，the technological capabilities can be enhanced rapidly，and the technological process development can be also responded to swiftly.
