Annular casing i.e. intermediate casing, for multi-stream turbojet engine of aircraft, has ring sector made of composite material, and another ring sector made of metal, where arms of ring sectors connect one element to another element
摘要
<p>The casing has a first element (22c) forming a hub (22T), and a second element (24c) formed at the first element. A ring sector is partially made of a composite material, and another ring sector is made of metal. Radial arms (23T) of the respective ring sectors connect the first element to the second element, where one of the arms of the latter ring sector is structural. The other radial arm of the former ring sector forms vane flow. The ring sectors are integrally formed and connected to each other by bolting.</p>
