无人驾驶飞机

The Switchblade, however, is a good candidate to be an unmanned aerial vehicle.

然而，这种"转向翼飞机"是无人驾驶航天器的理想候选机型。

This paper introduces the general structure of a small unmanned helicopter with taking-off weight 120 kg,describes the principle of the automatical driving system for this kind of helicoper,and proposes the use of the core sensor- position gyro ,for the system.

介绍了起飞重量为120 kg的小型无人直升机总体结构布局，简述了该飞机自动驾驶系统的工作原理，提出了要采用自动驾驶的核心感应器——姿态陀螺。

Unpiloted and looking rather like a large, fat fighter aeroplane , it is launched from a converted Boeing 747. Having released the upper stage at about one half satellite speed, the rocket-powered lower stage glides back to base and lands

X-34无人驾驶，外观更像一个庞大的战斗机，它从一个经过改造的波音747飞机上发射，当以约为卫星的一半速度释放上部一级火箭后，采用火箭发动机驱动的下部一级火箭就滑降回基地并着陆。

The wing stood up May 1, 2007, to manage Predator and MQ-9 Reaper unmanned aircraft systems, and train aircrews to fly them.

这个空军联队是在2007年1月成立的，其目的是为了管理&捕食者&和&MQ-9收割者&无人飞机系统，和训练机组人员来驾驶他们。

Today's killer drone is a slow-flying, easy-to-spot turboprop plane that drops relatively-crude munitions on its targets.

当今的攻击型无人驾驶机是一种飞得慢、容易被发现的涡轮螺桨推进飞机，向目标投弹精度也相对较低。

Military agencies such as DARPA (Defense Advanced Research Projects Agency) have funded a number of robotics programs using collaborative flocks of helicopters and fixed-wing aircraft, schools of torpedo-shaped underwater gliders, and herds of unmanned ground vehicles.

像国防高级研究项目机构之类的军事机构就已经为许多机器人操控项目提供了研发资金，这些项目的研究方向是直升机与固定羽翼飞机的合作群，鱼雷状的海底滑翔机群，与无人驾驶的地面车辆群。

A pilotless aircraft by remote .

遥控的无人驾驶的飞机。

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。
