The form2 ing technology of the large integral panels is an important key technology which must be solved during the de2 veloping process of an airplane. Starting from the structure characteristics of the large integral panels , the structure forms and classification of the integral panels are introduced , and the oversea research situation and the developing tendency of the shot peen forming and the creep age forming technologies for the panel with in2 tegral stringers are emphatically presented. The research basis and the existing problems of forming technolo2 gies of the integral panels in China are also analyzed. Especially , the newest achievements obtained during the developing process of ARJ21 regional jet plane are introduced. Finally , some suggestions and research empha2 ses are proposed for developing as quickly as possible the forming technologies of fuselage and wing panels of large aircraft. Key words : integral panel ; shot peen forming ; creep age forming ; large aircraft ; aluminum
