초록

A casing for a gas turbine includes a construction providing improved structural efficiency. Improved load paths and means for transmitting loads in the engine case are disclosed.

대표
청구항

We claim: 1. A casing for an aircraft turbofan bypass engine, the casing comprising: a case adapted to encircle the engine and having a plurality of engine mounts thereon adapted to mount the engine to an aircraft; an inner hub adapted to support at least one bearing supporting a main shaft of the engine, the inner hub supported inside the case by a plurality of struts extending between the inner hub to the case, the struts defining a primary load path from the inner hub to the case; and a splitter supported intermediate the inner hub and case by the st...
