摘要： A main rotor blade exhibiting a unique planform shape in which the blade chord increases from the root end of the blade inboard region to the outer main region of the blade, where the blade chord achieves a maximum chord at a spanwise location within the main region, then decreases toward a distal tip end. The leading edge preferably is generally straight while the trailing edge is contoured to define the chord. Another characteristic feature of the rotor blade design is the location of the blade-feathering axis in which the feathering axis is located at a mid chord position over some inboard length of the rotor blade then transitions to a quarter chord location. Another characteristic feature is an airfoil distribution along the blade span that transitions from a blunt trailing edge to a sharp trailing edge airfoil suited for mid-range Mach number operation. The tip region preferably utilizes a transonic flow airfoil. Another characteristic feature of the rotor blade design is an unconventional combination of positive and negative twist gradients.
摘要翻译：具有独特平台形状的主转子叶片，其中叶片弦从叶片内侧区域的根部端延伸到叶片的外部主区域，其中叶片弦在主区域内的翼展方向位置处达到最大弦线，然后朝向远端尖端减小。前缘优选地大体上是直的，而后缘被轮廓化以限定弦。转子叶片设计的另一个特征是叶片羽化轴线的位置，其中羽化轴线位于转子叶片的一些内侧长度处的中间弦位置，然后转变到四分之一弦的位置。另一个特征是沿着叶片跨度的翼型分布，其从钝的后缘转变成适用于中档马赫数操作的锋利的后缘翼型。尖端区域优选地使用跨音速流动翼型件。转子叶片设计的另一个特征是正负扭转梯度的非常规组合。

摘要： Fibers are made from thermoplastic polymers by supplying solid particles of the thermoplastic to a melting grid; heating the melting grid to a temperature sufficient to melt the thermoplastic; melting the thermoplastic particles on the heated melting grid such that the melted thermoplastic flows through the grid and is collected in a collecting chamber located beneath the melting grid; injecting into the collecting chamber below the melting grid an additive present in a non-aqueous carrier which carrier comprises organic rosin materials and a surfactant; without actuated mechanical stirring, forming a substantially homogeneous mixture from the injected additive; and extruding fibers from the substantially homogeneous mixture.

摘要： A process for making ready-to-tuft, mock space-dyed bulked continuous filament yarn is a one-step process. It joins extruding, texturing, and interlacing to yield a yarn that may be tufted directly into carpet without further texturing or twisting. In another aspect, one or more additional strands may be inserted in the process. An apparatus for making the ready-to-tuft, mock space-dyed, bulked continuous filament yarn is described.
