    • A take-off performance monitor uses a sensor to produce a movement signal proportional to the movement of an aircraft during a take-off roll and, for each take-off, historical data is generated and stored based on the movement signal. An analyzing unit of the monitor uses the historical data and current conditions to calculate a reference take-off distance, reference acceleration data and reference velocity data. This information is output to the pilor to facilitate his judgment as to the adequacy to take-off performance. In the preferred embodiment, the analyzing unit utilizes five samples of acceleration and velocity during a take-off roll to solve an equation for five constants that are indicative of take-off performance. The five constants relate to static thrust, a linear relationship between thrust and velocity, a non-linear relationship between thrust and velocity, air drag and rolling drag, and these five constants constitute at least part of the historical data. During an actual take-off the actual acceleration of the aircraft and the reference acceleration are displayed to allow the pilot to make a quantitative evaluation of the takeoff performance. This comparison can be made at velocities much below take-off velocity and thus will allow a safe abortion of abnormal take-offs. In addition to an acceleration comparison a live take-off distance, based on actual take-off acceleration, is displayed and compared to the reference take-off distance as predicted in part from historical data.
    • 起飞性能监视器使用传感器来产生与起飞辊中的飞行器的运动成比例的运动信号,并且对于每个起飞,基于运动信号生成和存储历史数据。 监视器的分析单元使用历史数据和当前条件来计算参考起飞距离,参考加速度数据和参考速度数据。 该信息被输出到pilor以便于他对起飞性能是否足够的判断。 在优选实施例中,分析单元在起飞辊期间利用五个加速度和速度的样本来求解表示起飞性能的五个常数的方程式。 五个常数涉及静态推力,推力与速度之间的线性关系,推力与速度之间的非线性关系,空气阻力和滚动阻力,这五个常数构成至少部分历史数据。 在实际起飞期间,显示飞机的实际加速度和参考加速度,以允许飞行员对起飞性能进行定量评估。 这种比较可以在低于起飞速度的速度下进行,从而允许安全地流产异常起飞。 除了加速比较之外,根据实际起飞加速度的实际起飞距离也将显示出来,并将其与参考起飞距离进行比较,部分来自历史数据。

    • The present invention relates to an improved die for use in textile processes involving nonwoven melt blown fabrics. In a melt blown process, molten polymer resins are injected into a melt blowing die and ejected or extruded from the die in the form of filaments. The present invention is directed to an improved die faceplate in combination with an extension plate that provides an extended flow path for an air jet to extrude a molten polymer filament of a reduced diameter in the melt blowing process.
