Abstract:
A method of equalizing the air temperature in a turbine engine air inlet, said method comprised of:a) providing a modulating plenum adjacent to and surrounding said turbine engine air inlet, said plenum filled with air; b) separating said modulating plenum from said turbine engine air inlet with a wall; c) providing the wall with a plurality of perforations, wherein at least one of the perforation is canted longitudinally, for permitting air flow between said modulating plenum and said turbine engine air inlet the plurality of perforations further being circumferentially spaced about a longitudinal axis of said plenum thus forming at least one ring of perforations; d) regulating pressure of the air in said modulating plenum, e) providing at least one air temperature sensor in said modulating plenum to monitor the temperature inside said plenum; and f) maintaining the air temperature in said modulating plenum at a determined temperature.
