| 2. | The prediction of the separation trajectories of the external stores carried out on aircraft is an important task in the aerodynamic design area
飞机投放外挂物的分离轨迹预测在气动设计领域是一个很重要的课题。 |
| 3. | The work of this paper include : 1 . the 3 - d solid entities of the external store , a missile , and the aircraft are modeled with a commercial cad software
在投放发射分离过程中，外挂物处于载机的近流场中，状态和姿态角的变化可能很大。 |
| 4. | The chimera embedding technique is presented for the external store separation configuration . it divides the whole region into many subdomains . euler equations are used for every subregion with the finite volume method
本文采用嵌套网格技术，将飞机投放外挂物的模型分成多个计算子域，对飞机投放外挂物的复杂外形进行了分区迭代求解。 |
| 5. | By 1955 the sea hawk performance was already considered mediocre which led to the installation of the more powerful 5 , 200 lb thrust nene 103 and the use of the sea hawk as a ground attack aircraft , cleared to carry external stores , a task at which the sea hawk excelled
到1955年，因为“海鹰”的表现只能说是差强人意，所以换装了推力为5 , 200磅的“尼恩” 103发动机，同时， “海鹰”的角色也转变为一架对地攻击机， “海鹰”携带的外挂武器完全可以胜任。 |
| 6. | This paper provides a powerful method for the compatibility design of aircraft with external store , a missile , by calculating fast , conveniently and effectively the relative trajectory and relative attitude of the store with respect to aircraft during the separation process
此外，为了有效击中目标，需要掌握投放初始阶段外挂物姿态和运动轨迹数据。因此，研究机载发射过程中的弹机气动干扰力，考虑其对导弹发射后的弹道仿真初始参数的影响十分必要。 |
| 7. | The investigation of the distribution of aerodynamic forces on the external stores and their neighboring aircraft surfaces during the transient process of the separation of the external store from an aircraft is an urgent need because aerodynamic interactions can cause the released store to impact upon , and possibly damage , the aircraft
从载机上发射导弹、投掷炸弹或抛弃副油箱时，外挂物处于载机复杂干扰流场中。此时往往出现不正常分离，有时会导致外挂物与载机发生碰撞，严重危及载机和飞行人员安全的重大事故。 |
