浮升混合飞行器体积巨大,质量与排开周围空气的质量相近,导致其附加质量效应明显,需要在分析时考虑其附加质量的影响.借助自编译user-defined function (UDF)的六自由度刚体运动程序,进行加速运动流场的瞬态计算;采用compu-tational fluid mechanics (CFD)方法,得到复杂外形的浮升混合飞行器附加质量矩阵.飞行器受到扰动时,模型本身受扰动趋于收敛;但由于附加惯性力的存在,不同情况下的运动状态量都会存在一定程度的振荡延迟.前向速度和俯仰角速度变化表明,无论是否考虑附加质量效应,垂向突风对这两个量影响都较小.另一方面,对于垂向速度和俯仰角而言,受到附加质量效应影响会导致振荡趋势变大.附加质量效应对浮升混合飞行器的操纵性有着明显的影响.对于前向速度和俯仰角,附加质量效应使得其操纵响应变得缓慢;而且俯仰角速度振荡趋势变大.%Buoyancy-lifting hybrid airship has a huge volume,and a mass similar to the surrounding air,which leads to the obvious effects of added mass,as a result,it is necessary to consider the added mass in relevant analy-sis. The user-defined function(UDF) program on the six degree of freedom motion equations of rigid body was de-veloped to carry out the transient calculation of accelerate flow field. And computational fluid dynamics (CFD) method was used to obtain the added mass matrix of buoyancy-lifting hybrid airship with a complex shape. The sim-ulation result showed that the motion of the airship tends to converge when disturbed,but there will be a certain de-gree of oscillation delay in the motion state in different circumstances due to the additional inertia force. The verti-cal gust has little impact on the motion state and pitch angle velocity, regardless of the additional mass effect. While the trend of oscillation of the motion state vertical velocity and pitching angle becomes larger when consider-ing the additional mass. The additional mass has a significant effect on the maneuverability of buoyancy-lifting hy-brid airship,the maneuvering response of forward velocity and pitch angle become slower,and the trend of pitching angular velocity becomes larger.
