推进剂

A type of high-performance fuel-rich propellant for the unchoked ducted rocket has been developed. The burning rates of the fuel-rich propellant are greater then 2mm/s at 0.5MPa, the greatest one is up to 4. 05mm/s. The burning-rate exponent is greater than 0.5, the highest one reaches 0.58. The fuel-rich propellant grain can combust steadily in the gas generator at 0.226MPa. The uniaxial mechanical properties and the processability of the fuel-rich propellant are good.

研制了一类用于非壅塞固体火箭冲压发动机的高性能铝镁贫氧推进剂：0.5MPa下燃速高于2mm/s，最高者达4.05mm/s；燃速压强指数高于0.5，最高者达0.58；直连式实验时，在0.226MPa下燃烧稳定；具有良好的力学性能和工艺性能。

In the second compartment, fillers are provided for absorbing and/or adsorbing at least a part of the propellant.

在第二室中装入用于吸收并／或吸附只要部分推进剂的充填物。

Typically, a well-designed injector atomizes a large population of propellant droplets to less than 0.004 inches (100 microns) in diameter.

通常情况下，一个设计良好的喷油器atomizes一个人口众多的推进剂液滴少于0.004英寸（ 100微米）的直径。

And a mass of 1.67 kg., was lofted by a 160 gram propellant grain in a B-200 motor...

这火箭，其中有一个整体的长度26英寸（ 66厘米）和大量的1.67千克，是lofted由一百六十零克推进剂药柱在一个 B - 200型汽车。。。

Film cooling provides protection from excessive heat by introducing a thin film of coolant or propellant through orifices around the injector periphery or through manifolded orifices in the chamber wall near the injector or chamber throat region.

气膜冷却提供保护，从过多的热量通过引入薄膜的冷却剂或推进剂通过口周围的喷油器周边或通过manifolded开口在会议厅内的墙壁附近的喷油器或分庭喉咙地区。

The mechanical properties of propellants formulation, which containes PEO binder and is plasticized by nitrate ester were studied.

对聚氧化乙烯为粘合剂硝酸酯增塑的高能推进剂配方力学性能进行了研究。

If the mission velocity and payload are low, the propellants are fed to the thrust chamber by pressurizing the vehicle tanks.

如果任务的速度和有效载荷低，推进剂是美联储向推力室由施压，车辆坦克。

The burning surface of a rocket propellant grain recedes in a direction perpendicular to this burning surface.

燃烧表面的火箭推进剂药柱消退在一个方向垂直于这燃烧的表面。

In actuality, slivers or fragments of propellant grain remain once the bulk of the grain has been consumed.

在实际上，条子或片段的推进剂药柱仍然是一旦大量的粮食已经消耗。

In reality, this region is not at all distinct, especially during the tail-off phase where slivers of propellant are certainly present.

在现实中，这个地区是不是在所有不同的，尤其是在尾小康阶段条子推进剂的当然是目前的。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
