The pressure difference on the wall between actuator and the exit of primary jet is great.

主流通道内侧压力差主要产生在激励器与主流出口之间的上下壁面上。

The pressure gradient and entrainment of vortexes are main reasons that synthetic jet actuator controls low speed primary jet direction.

压强梯度的存在和旋涡的卷吸作用是合成射流激励器控制宏观低速流流动方向的主要因素。

The actuator at an angle can change greatly the primary jet direction and has a good effect on thrust vectoring without increasing input power.

在不增加激励器输入功率的情况下，带倾角激励器可以极大地增加主流偏转角度，推力向量控制效果很好。

The main reason for these projects is not to develop primary power sources for jet-turbine powered aircraft, but to build small, highly efficient fuel cells that could be used to make greener airliners.

ECONOMIST: Electric planes

One of the aircraft's two batteries was replaced in October after it failed to start the jet's engines, the battery's primary function.

The evolution of executive grandeur from very comfortable to jet-setting reflects one of the primary reasons that the gap between those with the highest incomes and everyone else is widening.
