Abstract：The civil aircraft’s fuselage segmenting is the key principal in the conceptual design stage. There are
many problems due to the unpredicted economical reason will be met during the operation. After the real practice on the
Chinese civil aircraft, we want to provide a solution the fuselage segmenting based on the country industry policy and the
enter-prise’s industrial work division rule. the expected selling and the annual production are used to decide the fuselage
segmenting’s number, and the difficulty of the fabricating and assembling are used to judge the segmenting surfaces. This
method has be evaluated and accepted by the foreign aircrafts’ segmenting also.
