摘要： The present invention relates to apparatus for influencing fluid flow over a surface, and more particularly, but not exclusively, to turbulent boundary layer flow drag reduction for an aircraft. The present invention provides such apparatus including a plasma generator comprising a first electrode (7) and a signal generator (18), the apparatus being operable to drive the first electrode (7) with a pulsed signal generated by the signal generator (18) thereby to cause a change in direction of the flow of the fluid over the surface.

摘要： In order to discriminate between laminar flow and turbulent flow states, andto provide an indication, e.g.to a pilot of an aircraft of air flow over an aircraft wing, a sensor mounted on the wing provides an analogue signal of airflow, and an intermittency value of the analogue signal is derived in analogue circuitry including an AC coupling of the signal to an integrator for integrating the signal for a preset time. The integrated value is compared with a threshold value to indicate whether the intermittency represents quiet laminar flow or noisy turbulent flow.
摘要翻译：为了区分层流和湍流状态，并且提供诸如飞机机翼上的空气流的飞行员的指示，安装在机翼上的传感器提供气流的模拟信号，并且间歇的值模拟信号在模拟电路中得到，包括信号与积分器的AC耦合，用于在预设时间内对信号进行积分。将积分值与阈值进行比较，以指示间歇性是否表示安静的层流或嘈杂的湍流。

摘要： To provide an indication of whether airflow is separated, as opposed to (5) other states of flow, over a surface, two or more adjacent sensors at a location on the surface each produce an analogue signal representative of airflow. The analogue signals are correlated with each other, and the degree of correlation indicates whether the airflow is in a separated state.The correlation may be carried out by comparing processedvalues of the analoguesignals, and (10) thresholding the comparison result.
摘要翻译：为了提供气流是否分离的指示，与（5）其他流动状态相反，在表面上，表面上的位置处的两个或更多个相邻传感器各自产生表示气流的模拟信号。模拟信号彼此相关，相关程度表示气流是否处于分离状态。相关性可以通过比较类似信号的处理值，（10）阈值比较结果来进行。
