ABSTRACT:
A friction-damped combustor cowl is formed of first and second plies of sheet material of mating, generally annular configuration defining a central cowl axis and of axially elongated and aerodynamically contoured configuration have respective fore end portions which are curled to form a cowl leading edge of arcuate cross section and corresponding fore edges which are integrally joined, and respective aft end portions which define a cowl trailing edge and corresponding aft edges which are integrally joined. Surface contact of the contiguous surfaces of the laminated and mating first and second plies provides vibration damping under normal operating conditions in an alternative and combustor cowl, a spring element is received and maintained under compression within the curled leading edge of the combustor cowl and maintains a resilient biasing force maintaining surface contact between the spring element and the interior surface of the curled leading edge, thereby maintaining frictional surface contact and requisite vibration damping under normal operating conditions.
