摘要： A compressor scroll housing for use in conjunction with turbo-machinery, particularly applicable in aircraft. The scroll housing can include a plurality of scroll vanes arrayed around the scroll housing. Scroll vanes, integrally formed with the scroll housing, carry stress load on the scroll housing, including the load from fluid pressure within the scroll and carcass loading from the engine. The plurality of scroll vanes adapted for guiding flow of fluid from an inlet to an outlet while supporting the scroll housing. Chord length and cross sectional area of each scroll vane can be sized to maintain an equal stress in all scroll vanes. A method of making the scroll housing for use with an impeller connected to an engine is disclosed, as well as a method of operating turbo-machinery including supporting a load on the scroll housing with scroll vanes while maintaining an equal stress on each scroll vane.

摘要翻译： 一种与涡轮机械结合使用的压缩机涡旋壳体，特别适用于飞机。 涡旋壳体可以包括围绕涡旋壳体排列的多个涡旋叶片。 与涡旋壳体一体形成的涡旋叶片在涡旋壳体上承受应力负荷，包括来自涡卷内的流体压力的负载和来自发动机的胎体负载。 多个涡旋叶片适于在支撑涡旋壳体的同时引导流体从入口到出口的流动。 每个涡旋叶片的弦长和横截面面积的尺寸可以确保在所有涡旋叶片中保持相等的应力。 公开了一种制造与连接到发动机的叶轮一起使用的涡旋壳体的方法，以及一种操作涡轮机械的方法，包括在涡轮叶片上支撑负载，同时在每个涡旋叶片上保持相等的应力。
