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.
