Abstract
A variable area bypass injector (VABI) seal for a variable cycle gas turbine engine includes a circumferentially segmented seal attached to the diffuser. Each seal segment is spring loaded to allow for different axial movement between circumferentially adjacent segments, and has a seat portion complimentary to a VABI valve conical surface for sealingly engaging the VABI valve when the VABI valve is in closed position. Additionally, the seal segments are shaped with a low aerodynamic profile and cooperate with the VABI valve conical surface, when the valve is in an open position, to provide an annular conic channel that keeps the bypass flow attached to the VABI valve and core flowpath walls as it is injected into the core gas stream.
