查询词典 hover

Results show that in hover the fuselage normal force and pitching moment are relatively high due to the influence of rotor/wing downwash; and in low speed forward flight, the downwash have strong interaction on the normal force and pitching moment of fuselage due to the big dimension horizontal tail; the effects of downwash on the fuselage rolling and yawing moments are little and the influence on fuselage side force is considerable.

结果表明，悬停时受主机翼高速旋转产生的下洗尾流影响，机身产生了较大的法向力和低头力矩；前飞时下洗尾流对机身的法向力和俯仰力矩有比较严重的干扰，对滚转力矩和偏航力矩干扰较小，对侧向力有一定影响。

In order to calculate the helicopter hover ceiling in OGE precisely, some aerodynamic parametem, such as tip loss effect, induced velocity distribution, the effect of rotor downwash on the fuselage and power transfer of engine into rotor, must be treated carefully.

准确计算直升机的悬停升限依赖于诸如桨尖损失系数，非均匀旋翼诱导速度分布，旋翼下洗引起的直升机增重效应及发动机与旋翼之间的功率传递系数等气动参数的准确度。

The 那个 F-35 Lightning II 架F - 35闪电II looks really awesome, especially in VTOL/hover mode, but I really don't understand why the US Air Force considers a super-heavy 70,000-pound as the future.

看起来非常可怕的，尤其是在垂直起降/悬停模式，但我真的不明白为什么美空军认为，超稠油70，000磅的未来。

"Second Life is remarkably easy to work with, and is very popular,"

"第二次生命是显着容易的工作，并且很受欢迎，"

For example, we usually assume that materials are homogeneous and isotropic and free of internal defects or flaws.
