外形

Also known as Barnard 33, the unusual shape was first discovered on a photographic plate in the late 1800s.

After the airdrop experiments of the system of the projectile and speed-down parachute, the balance velocity obtained from the optics apparatus on the ground、the balance spinning speed obtained from the gyroscope on the projectile and the image obtained from the infrared detector on the projectile are all used to simulate the six-dimension exterior trajectory of the projectile and identify the roll damping moment derivatives, and the identification can safely come to a conclusion that the absolute value of roll damping moment derivatives from the engineering calculation are on the low side.

对卷弧尾翼弹与减速伞系统进行空投试验，由地面光测系统给出平衡落速、弹上陀螺给出平衡转速、弹上红外探测器拍摄地面图像判断弹的姿态。通过六自由度弹道模拟，对弹滚转阻尼导数进行参数辨识，得到工程估算所得滚转阻尼导数绝对值偏小的结论。 5。对空投试验中出现弹姿态摆动现象，从受力分析及红外图像分析两个方面进行探讨，给出合理解释，并根据分析对弹外形进行修改，在后来的试验中收到很好的效果。

And the width with unoccupied place belt of crystal of phonon of this kind of form following branch and central frequency can follow phonon crystal sheet of appearance of geometry of unit of the construction inside afterbirth change and change.

而且这种准分形声子晶体带隙的宽度及中心频率会随声子晶体单胞内结构单元几何外形的改变而改变。

The quadratic polynomials and Kriging method are employed to construct the response surface separately, Numerical results indicate that the forebody and afterbody designed by us is of simple configuration, not only can it ensure the efficiency of propulsion system, but also have a better aerodynamic performance.

响应近似模型分别采用了二次多项式和kriging方法来构造，结果表明由本文设计的前后体外形结构简单，不仅能确保推进系统的工作效率，而且具有更好的气动性能。

This way is quite different from the former way, which only take the forebody and afterbody as the extend of engine inlet and spout, and surround the engine to optimize the forebody and afterbody, thus neglecting the effect with the whole aerocraft layout.

本文设计工作在保证发动机稳定及高效率工作的条件下，充分考虑前后体对整个飞行器气动性能的影响，不同于以往只将前后体作为发动机进气道和喷管的延伸，围绕发动机来优化前后体外形，而忽视其对整机布局设计的影响。

The designing way of this paper about the forebody and afterbody of aerocraft is based on the wave-rider theory, so design the aerocraft upper and down surface separately, besides keeping the length and thickness of forebody and afterbody constant, to some extent ensure the whole aerocraft design target and avoid the conflict with other disciplines, The flow solver takes use of Euler equations, combining with the technique of the unstructured dynamic meshes.

文中对飞行器前后体设计思路基于高超音速乘波体的思想，将飞行器上下表面进行分离设计，在前后体的长度厚度以及发动机的位置保持不变的条件下，较大程度避免了飞行器整体外形布局的改变，从而一定程度上保证了总体设计的目标，大大缓和了与飞行器其他学科设计时的冲突。
