    • An aircraft control system for an unique-trim, model-following system includes a feedforward shaping function that provides quickening of pilot input, and an automatic trim function that accommodates return of the cockpit controller to an unique, centered position during trimmed flight. The basic control law is reconfigured in response to the changing state of landing gear contact to support transitions between ground state and fly state conditions. The state of the landing gear is monitored continually to recognize the occurrence of initial ground contact and whether the aircraft is constrained about a rotational axis due to ground contact. The control is altered progressively as the transition proceeds so that command of the control surface is consistent with the degree of constraint imposed by ground contact.
    • 用于独特装饰,模型跟踪系统的飞行器控制系统包括前馈整形功能,其提供先导输入的加速,以及自动调整功能,其适应在修剪飞行期间驾驶舱控制器返回到独特的中心位置。 响应于起落架接触的变化状态来重新配置基本控制律,以支持基态和飞行状态之间的转换。 始终监视起落架的状态,以识别初始地面接触的发生以及由于地面接触而使飞机受到旋转轴的约束。 随着过渡的进行,控制被逐渐改变,使控制面的指令与地面接触所施加的约束程度一致。

    • Unusually high loading levels of smectite minerals are found to provide excellent pigment spacing in aqueous-based coatings, as will enable desired improved hiding, thereby extending the pigment. The level of smectite used in accordance with the invention is sufficiently high that the high gelling efficiency smectites previously used as thixotropes would be inappropriate, and would yield viscosities so high as to render the aqueous coating composition lacking in desired flowability properties. Thus in accordance with the present invention, there is mixed with the aqueous carrier and pigment at least 0.5% by weight of the total composition, of a particulate water swellable smectite which has a gelling efficiency such as to display a 20 rpm Brookfield viscosity of less than 900 cps when subjected to the standard gelling test herein, with the amount of the smectite in the composition not exceeding that which would raise the viscosity of the composition above 110 Krebs Units (KU).
    • 发现蒙皂石矿物的非常高的载量水平在水基涂料中提供优异的颜料间隔,这将使得需要改进的遮盖性,从而延长颜料。 根据本发明使用的蒙皂石的含量足够高,以前用作触变剂的高凝胶效率的绿土是不适当的,并且将产生如此高的粘度使得水性涂料组合物缺乏所需的流动性能。 因此,根据本发明,将水性载体和颜料与总组合物的至少0.5重量%混合,其具有胶凝效率的颗粒状水可膨胀蒙脱石,以显示20rpm的Brookfield粘度较低 当进行本文的标准胶凝试验时,超过900厘泊,组合物中蒙皂石的量不超过将使组合物的粘度提高至高于110克仑兹单位(KU)的量。
