Claim 0:
1. An aeroderivative gas turbine comprising: a casing having adjacent channels separated by ribs; a compressor having a rotor mounted on a generator shaft supported for rotation in the casing; a combustor; a high pressure turbine arranged in the casing and comprised of a rotor mounted on the generator shaft for co-rotation with the compressor rotor; a power turbine arranged in the casing and comprised of a rotor mounted on a turbine shaft to drive a load; a thermal insulation panel coupled to the casing to reduce heat dispersion through the casing, the insulation panel comprising a metal sheet having an outer surface and an inner surface and an insulating sheet comprising a quilted panel encased in woven glass cloth coupled to the outer surface of the metal sheet and an air manifold located at one end of the thermal insulating panel and with access to an air inlet that permits cooling air into the channels, wherein the inner surface of the metal sheet contacts the ribs of the casing to enclose the channels and form passages bounded by the inner surface of the metal sheet and the outer surface of the casing; and wherein the adjacent channels are configured to allow cooling air to circulate therethrough when the rotor is working and allow air in the passages to act as a thermal insulator for the rotor when the rotor is idle, and wherein each of the passages are completely bordered so that none of the laterally spaced adjacent passages extend into each other.
