The invention discloses an aircraft composite material oil tank and a design method thereof in the technical field of composite material oil tanks. The aircraft composite material oil tank comprises multiple oil tank barrel sections, an oil tank connecting frame, an end face sealing plate, an internal partition frame and a covering cap. The multiple oil tank sections are connected through oil tank connecting frames. The oil tank connecting frame is sleeved with the front and rear oil tank barrel sections; a plurality of internal bulkheads are arranged in the plurality of oil tank sections; the internal bulkhead is connected with the inner wall of the oil tank barrel section in a riveting and sealing manner; the covering cap is arranged at the front ends of the multiple oil tank barrel sections; the rear ends of the multiple oil tank barrel sections are sealed through end face sealing plates. An outer skin is further bonded to the whole tank body of the multiple oil tank barrel sections. The oil tank is segmented in the length direction and is divided into a multi-segment structure to be assembled and connected; production and manufacturing of the oil tank with the special-shaped section are achieved, installation and sealing of internal pipelines of the oil tank are guaranteed, and the overload requirements under various flight working conditions are met.
