摘要： Methods and apparatus for fabricating a rotor blade for a gas turbine engine are provided. The rotor blade includes an airfoil having a first sidewall and a second sidewall, connected at a leading edge and at a trailing edge. The method includes forming the airfoil portion bounded by a root portion at a zero percent radial span and a tip portion at a one hundred percent radial span, the airfoil having a radial span dependent chord length C, a respective maximum thickness T, and a maximum thickness to chord length ratio (Tmax/C ratio), forming the root portion having a first Tmax/C ratio, forming the tip portion having a second Tmax/C ratio, and forming a mid portion extending between a first radial span and a second radial span having a third Tmax/C ratio, the third Tmax/C ratio being less than the first Tmax/C ratio and the second Tmax/C ratio.
摘要翻译：提供了一种用于制造用于燃气涡轮发动机的转子叶片的方法和装置。转子叶片包括具有第一侧壁和第二侧壁的翼型件，其在前缘和后缘处连接。该方法包括以零百分比的径向跨度形成由根部限定的翼型部分和以百分之一百的径向跨度的顶端部分，翼型件具有径向跨度依赖的弦长C，相应的最大厚度T和最大值厚度与弦长比（Tmax / C比），形成具有第一Tmax / C比的根部，形成具有第二Tmax / C比的尖端部分，以及形成在第一径向跨度与第二径向间隔之间延伸的中间部分具有第三Tmax / C比的径向跨度，第三Tmax / C比小于第一Tmax / C比和第二Tmax / C比。

摘要： A wheelchair assembly featuring an adjustable support comprised of two inflatable pillows that are housed in a single cover or separate, discrete covers which are releasably adjoined to each other. The support is releasably attached by adjustable straps to wheelchair armrests and is adapted to provide enhanced support for the user's body and remain stationary when the user's body is rested thereon. The invention is also directed to a wheelchair support comprising two inflatable pillows housed in a single cover or two separate covers. The invention is further directed to a highly adjustable travel pillow comprised of two inflatable cushions that are preferably housed in separate, discrete covers which are releasably adjoined to each other. The back of the travel pillow cover has an anti-skid material to maintain its position.
摘要翻译：一种具有可调节支撑件的轮椅组件，其包括两个充气枕头，两个可充气枕头容纳在单个盖子中或分离的离散盖子，其可释放地彼此邻接。支撑件可调节的带子可释放地附接到轮椅扶手上，并且适于为使用者的身体提供增强的支撑并且当使用者的身体放置在其上时保持静止。本发明还涉及一种轮椅支架，其包括容纳在单个盖或两个单独盖中的两个可充气枕头。本发明进一步涉及一种高度可调节的旅行枕头，其包括两个可充气垫，其优选地容纳在彼此可释放地邻接的分离的离散盖中。旅行枕头背面有防滑材料，以保持其位置。

摘要： A travel pillow comprising a front having a thin planar portion for receiving the user's head and one or two lateral forwardly projecting cushioning portions. The distance the lateral cushioning portions project forward gradually increases from the thin planar portion to a peripheral portion of the travel pillow in an arced manner. The back of the pillow comprises an anti-skid material such as silicone coated fiberglass weave which keeps the pillow stationary when the user rests his/her head against the pillow. The user places the pillow on the seat and then rest the back of his/her head on the thin planar portion of the pillow. The user can then tilt or turn his/her head in many different positions on a lateral cushion and the pillow will remain stationary.
摘要翻译：一种旅行枕头，包括具有用于接收使用者头部的薄平面部分的前部和一个或两个横向向前突出的缓冲部分。横向缓冲部分向前突出的距离从移动枕头的薄平面部分逐渐增加到行进枕头的周边部分。枕头的后部包括防滑材料，例如硅树脂涂覆的玻璃纤维编织，当用户将头枕靠在枕头上时，其保持枕头固定。用户将枕头放在座位上，然后将他/她的头部的背部放在枕头的薄平面部分上。然后，用户可以在侧垫上倾斜或转动他/她的头部在许多不同位置，并且枕头将保持静止。
