Inlet bleed heater for heating inlet air to a compressor and methods of fabricating and transporting the heater

An inlet bleed heater for a compressor comprising:

• a housing defining an air inlet duct for delivering ambient air along a flowpath to the compressor;
• a plurality of tubes in the flowpath of said air inlet duct, said tubes adapted for receiving heated extraction air from the compressor;
• each said tube including a plurality of apertures spaced from one another for discharging the heated air from the tubes into the flowpath for mixing with the ambient inlet air passing the tubes to supply heated air to the compressor;
• and
• a manifold carried by said housing for supplying the extraction air from the compressor to the tubes, said manifold and each of said tubes being connected to one another by a bellows enabling relative movement between the manifold and the tubes in response to thermally induced forces.
