Title:
VARIABLE FLOW GAS TURBINE ENGINE
Document Type and Number:
Japanese Patent JPS6111405
Kind Code:
A
Abstract:
A variable flow gas turbine engine of the type having a combustor for generating combustion gases and a turbine rotor for receiving and expanding the hot combustion gases, has an outer wall and an end wall defining a channel for directing the flow of combustion gases from the combustor to the rotor; a plurality of fixed guide vanes mounted in the channel, the space between adjacent vanes forming at least one throat; a winglet fixedly mounted in the throat for separating the gases flowing through the throat into first and second streams; and a passage through at least one of the vanes into the throat, the passage being in fluid communication with source of air under pressure for injecting high pressure into the throat for varying the flow of combustion gases through the second stream. A method for varying the effective flow area of combustion gases in a gas turbine engine is also disclosed.
