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 connected to and structurally integrated with the engine casing. Cooling air is aspirated through the passageways (37,39) to maintain the inner portions of the beams (34,38) at essentially the same temperature as the outer surface of the sidewall (32). The flow of cooling air is metered. The cowl (30) acts as a beam and shares bending loads with the engine-casing.
