查询词典 turbofans

Research in areas such as new materials and improved blade design will provide incremental improvements to high-bypass turbofans. But it is unclear whether these will be enough to achieve the required fuel savings. A completely new type of engine may be needed.

新材料与叶片设计等方面的研究将会使高旁通比涡扇发动机获得不断的改进，但是否能够达到预期的节油目标还是个未知数，也许还需要研制一种全然不同新型发动机。

However, none of the submitted designs were considered any further by the Air Force, mainly because the aerodynamic configurations and the bypass ration of the turbofans were considered inadequate.

然而，美国空军没有更多任何一个提交的设计，主要的原因是空气动力结构和涡扇发动机的旁路配给量被认为不合适。

Rolls-Royce and General Electric are studying this approach, though they are also keeping their options open by working on improvements to conventional turbofans, too.

罗尔斯-罗伊斯公司（Rolls-Royce）与通用电气公司除了致力于改进常规的涡扇发动机外，都正在加大投入研制这种发动机。他们也没有对这两种发动机的优劣作出评判。

Aside from these attributes, the HEET engine is virtually identical to the current generation of turbofans in wide use aboard commercial airliners and business jets.

除去这些特点外，HEET引擎实际上同现在广泛使用在商业客机和商务喷气机上的涡轮引擎没有什么差别。

The latest "high bypass" turbofans, such as the Rolls-Royce Trent, push around nine times more air around the core of the engine than through it.

涡轮带动风扇又吸入了更多的空气，这样就产生了连续的循环。

As a planetary craft, the banshee wouldn't need high-powered engines to achieve escape velocity and fight in orbit, so instead technicians fitted it with economical twin turbofans.

作为星球内航空器，女妖不需要大马力的引擎来脱离周转速度或在星球轨道上作战，因此技术人员安装了两个经济型的涡轮风扇发动机取代引擎。

As a planetary craft, the banshee wouldn't need high-powered engines to achieve escape velocity and fight in orbit, so instead technicians fitted it with economical twin turbofans.

作为一种行星表面使用的飞行器，女妖战机不需要一台能逃脱星球的引擎并在轨道上战斗，取而代之的是一种技术人员认为比较合适的双涡轮风扇发动机。

The latest "high bypass" turbofans, such as the Rolls-Royce Trent, push around nine times more air around the core of the engine than through it.

最近的高涵道比涡轮风扇，例如罗罗的遄达发动机，推动空气通过发动机核心周围的空气相较于通过核心气量9倍。

The latest "high bypass" turbofans, such as the Rolls-Royce Trent, push around nine times more air around the core of the engine than through it.

像 Rolls-Royce Trent这样最新型的高旁通比涡扇发动机，在涡轮四周流过的气体是通过涡轮气体的9倍。

As a planetary craft, the banshee wouldn't need high-powered engines to achieve escape velocity and fight in orbit, so instead technicians fitted it with economical twin turbofans.

设计师们为女妖战机量身打造了一套经济型双涡轮喷射引擎，因为作为只在行星大气层内作战的飞行器，其并不需要高性能的引擎来达到在既定轨道战斗所需的能量以及逃逸时所需的速度。

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。
