无翼的

After compared with the experiment results, computational results have some error to theexperiment results, but it is same with the variation tendency of the experimental values.

随后对有小翼风力机和无小翼风力机的压力特性、速度特性进行了比较，得到了风力机叶尖加上小翼后，风力机叶端流场的变化。

Pteranodon was a large Pterosaur, notable for its skull crest.

According to the design performance aim, we estimate the overall parameters and complete the shape design of two schemes. Normal and tailless layouts are respectively applied. Then we use different airfoil and wing with low Reynolds number and the aerodynamic analysis of the result is achieved.

根据设计性能指标，进行总体参数估算，完成了两种方案的外形设计，分别采用了正常和无平尾的布局形式，进行了不同的低雷诺数翼型和机翼配置，并对设计结果进行了气动分析。

Seeds uniseriate, wingless, oblong, flattened; seed coat minutely reticulate, slightly mucilaginous when wetted; cotyledons accumbent.

种子单列，无翼，长方形，扁平；网状的种皮微小的，被弄湿的黏的稍；子叶依着。

Its name means "wingless" in Greek, and the Aptera's body materials and aerodynamics are borrowed from light aircraft.

它的名字意味&无翼&在希腊，并且Aptera的身体材料和空气动力学从轻型飞机被借用。

In the method ,the blades are treated as rigid ones with offset and spring restrained hinges and with structural coupling between flap and lead lag motion for the purpose of being applicable to hingeless or starflex rotors .

采用带外伸量及弹性约束的当量铰桨叶模型，考虑了旋翼挥／摆结构耦合及动力入流非定常气动力，建立了悬停状态旋翼／机体耦合动稳定性分析方法，适用于星形柔性及无铰式等旋翼系统。

Young stems terete to frequently 4-angled or subalate, glabrous, puberulous, pubescent, or tomentose, often glabrescent.

嫩茎圆柱状到经常地四棱形或略似翼的，无毛，被微柔毛，短柔毛，或被绒毛的，通常后脱落。

It adopted the integration of non-wings are tail wing configuration to fly from nose to tip for the acute angle into, but from top to bottom is curved arch of the fixed front, for the front straight edge of the wing after the double-W, There are four pairs of a combination of aileron, elevator and the flap functions to manipulate the face, with its own aircraft and more than 4 degrees fly-by-wire flight control system to complete match.

该机采用了翼身融合的无尾飞翼构形，从机头至翼尖为成锐角、但上下是拱弧形的固定前缘，前缘为直线，机翼后缘成双W形，有四对综合了副翼、升降舵以及襟翼功能的操纵面，与飞机本身的4余度电传操纵系统相配合完成飞行控制。

Reed was excited about the concept, and began testing a series of small balsa wood and tissue-paper lifting bodies which he flew down the hallways of the center's main office building and off its roof.

无翼设计让里德异常兴奋，他开始测试一系列轻质木材和薄页纸制成的航空航天器——将中心主办公大楼的走廊当成跑道，并在大楼屋顶起飞。

Second, the flows over the NACA 0012 airfoil and a two-element airfoil were calculated to validate the developed gridless method.

其次，为验证无网格边界处理方法，计算了NACA0012翼型，多段翼型的流场，并与结构网格计算结果进行了比较。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
