The invention relates to a pipe, a vehicle using the pipe and a method of manufacturing the pipe. The duct includes an exoskeleton structure and a sound absorbing structure disposed within the exoskeleton structure and conforming to the exoskeleton structure. The exoskeleton structure provides external mechanical support for the sound absorbing structure, thereby helping maintain the tubular shape of the sound absorbing structure. The external support does not interfere with the air flow in the sound absorption structure. In addition, external positioning of the exoskeleton structure allows for integration of various support mounting features for mounting the pipe in the vehicle. In some examples, the exoskeleton structure includes a plurality of closed openings to reduce the weight of the exoskeleton structure and provide additional flexibility. In addition, additive manufacturing of exoskeleton structures allows for the achievement of unitary structures having the various features and characteristics described above.
本申请涉及管道、使用管道的交通工具及制造管道的方法。管道包括外骨骼结构和吸声结构,该吸声结构设置在外骨骼结构内并与外骨骼结构相符。外骨骼结构为吸声结构提供外部机械支撑,从而有助于保持吸声结构的管状形状。该外部支撑不会干扰吸声结构内部的气流。此外,外骨骼结构的外部定位允许用于将管道安装在交通工具中的各种支撑安装特征的集成。在一些示例中,外骨骼结构包括多个封闭开口,以减轻外骨骼结构的重量并提供额外的柔性。此外,外骨骼结构的增材制造允许实现具有以上描述的多种特征和特性的整体结构。
