Claim:
1. A flow control assembly for controlling a cooling flow of a turbine engine having a compressor and a turbine, the compressor having an exit guide vane and the turbine having a turbine vane and a turbine blade, said flow control assembly comprising: a first flow control device comprising a first sidewall and a second sidewall, said first sidewall coupled to the exit guide vane and the turbine vane and configured to define a first flow path from the compressor to the turbine vane, said second sidewall coupled to the exit guide vane and to the turbine blade and configured to define a second flow path from the compressor to the turbine blade; a second flow control device coupled to the exit guide vane and in flow communication with said first flow control device, said second flow control device comprising an orifice device coupled to the exit guide vane and a meter device coupled to said orifice device, said orifice device configured to direct the cooling flow to said meter device; and a controller coupled to said second flow control device and configured to control said meter device to facilitate regulating the cooling flow into at least one of said first flow path and said second flow path.
