ABSTRACT:
The present invention discloses means and method for modulating the bypass flow in a mixed flow, variable cycle gas turbine engine. The engine includes means to vary the bypass flow and includes an augmentor and liner with coolant supplied by a portion of the bypass flow. The bypass flow pressure is modulated by sensing the pressure of the liner coolant and the pressure in the augmentor and varying the flow pressure as a function of P.sub.1, P.sub.2, or both.
