The invention provides a wing hanging auxiliary fuel tank which comprises a front section, a middle-rear section and empennages, the front section and the middle-rear section form an auxiliary fuel tank structure shape similar to a dolphin shape, and the empennages are arranged on the two sides of the tail of the middle-rear section. According to the auxiliary fuel tank, the requirement for the capacity of the auxiliary fuel tank of the aircraft voyage and the combat radius is effectively met, meanwhile, the requirement for mounting geometric compatibility is met, by adopting the dolphin-like shape conforming to pneumatic design, the aerodynamic characteristic and the large-capacity requirement are compatible, the cruise lift-drag ratio is increased, the flight resistance is reduced, the empennage serves as a horizontal stabilizer, and the service life of the auxiliary fuel tank is prolonged. The stability of the auxiliary fuel tank in the pitching direction is improved, and the influence on the longitudinal static instability of an airplane is reduced.
本申请提供了一种机翼挂装副油箱,包括:前段、中后段及尾翼,所述前段与中后段构成类海豚外形的副油箱结构外形,所述尾翼布置在中后段的尾部两侧。本申请提供的副油箱有效解决了飞机航程和作战半径的副油箱容量需求,同时满足挂载几何相容性要求,通过采用符合气动设计的类海豚型外形,兼容了气动特性与大容量需求,提高了巡航升阻比和减小了飞行阻力,尾翼作为水平安定面,增加了副油箱俯仰方向的稳定性,减小对飞机纵向静不安定度的影响。
