초록

In an aircraft, a jet engine is carried by a frame (4), and the engine core casing (18B) acts as a beam. An engine core cowl (30) is made of a composite material that maintains structural strength within a given temperature range. The outer surface of the cowl (30) is cooled by the ambient airstream. The sidewall (32) of the cowl (30) is stiffened by a plurality of beams on its inner surface, preferably including axial beams (34) and circumferential beams (38). The beams (34,38) are tubular and have interconnecting passageways (37,39). The cowl (30) is c...
