The invention relates to an aircraft fuel tank and an aircraft, and relates to the technical field of aircrafts. The fuel tank comprises a fuel tank shell, a lifting lug, a clamping plate assembly and a thermal protection assembly. And a first unthreaded hole is formed in the oil tank shell. The clamping plate assembly is attached to the inner side face of the oil tank shell; the lifting lugs are located on the outer side face of the oil tank shell and detachably connected with the clamping plate assembly through the first unthreaded holes so as to fix the outer side face of the oil tank shell. And the thermal protection assembly is attached to the outer side face of the oil tank shell and wraps the outer side face of the lifting lug. The oil tank shell made of the carbon fiber composite material serves as a bearing base body, a sandwich clamping structure is adopted, the clamping plates and the lifting lug flanges are clamped on the inner side and the outer side of the shell, mounting of the lifting lugs is achieved, and the bearing requirement is met; the heat-proof stop block is designed at the front end of the lifting lug, the lifting lug is prevented from being directly heated by pneumatic heat, meanwhile, the heat-proof and heat-insulation cover plate covers the outer side of the mounting structure of the lifting lug, and the purpose of heat protection of the lifting lug is achieved.

    本申请涉及一种飞行器油箱及飞行器,涉及飞行器技术领域。其包括:油箱壳、吊耳、夹板组件和热防护组件;油箱壳,其上开设有第一光孔。夹板组件,其贴设于油箱壳内侧面;吊耳,其位于油箱壳外侧面,吊耳通过第一光孔与夹板组件可拆卸地相连,以固定油箱壳外侧面。热防护组件,其贴设于油箱壳外侧面,热防护组件包裹于吊耳外侧面。本申请通过以碳纤维复合材料油箱壳体作为承载基体,采用三明治的夹持结构,将夹板与吊耳法兰夹持在壳体内外两侧,实现了吊耳的安装,并满足承载的要求;在吊耳的前端设计防热挡块,避免了气动热对吊耳的直接加热,同时采用防隔热盖板覆盖在吊耳的安装结构外侧,达到了吊耳热防护的目的。
