Abstract: The thickness of rocket motor dome wound with filament is not uniform.The shape of dome,the width of filament band and the opennings at both endsall effect the thickness of the case.In this paper,various methods to predict dome thick. ness are reviewed,and a new calculation method of dome thickness is derived from thegeometric relation of wound band.The dome thickness of an actual case is calculatedwith the methods mentioned above.The calculation results are compared with the thickness measured actually.
