Integrated pultruded composite profiles, such as rotor wings and blades, for electric vertical take-off and landing aircraft, lightweight helicopters, wind turbines, and other rotor wing applications, and integrated design and processing methods for making the same are disclosed. A plurality of web ribs are provided for reinforcing and supporting an outer skin, which may include a fabric layer, a metal skin, or a thermoplastic composite skin. The invention further discloses a process and method for continuous pultrusion of the integrated composite airfoil profile with variable aerodynamic torsion. Also disclosed is the use of a stranded wire cord that enables the leading edge counterweight to be continuously fed in situ into the pultrusion process and effectively retained in the pultrusion product. Use of a fiber reinforced structure impregnated with a matrix resin carrying high density powder for a leading edge counterweight is also disclosed.
公开了用于电动垂直起降飞行器、轻型直升机、风力涡轮机和其他转子翼应用的集成拉挤成型复合型材、例如转子翼和叶片,以及用于制造其的集成设计和加工方法。本发明提供了用于加固和支撑外蒙皮的多个腹板肋,该外蒙皮可以包括织物层、金属蒙皮或热塑性复合蒙皮。还公开了一种连续拉挤成型具有可变空气动力学扭转的集成复合翼型型材的工艺和方法。还公开了绞合金属丝绳的使用,其使得前缘配重能够在原位连续供给到拉挤成型工艺中并有效地保留在拉挤成型产品中。还公开了用于前缘配重的以载有高密度粉末的基体树脂浸渍的纤维增强结构的使用。
