ABSTRACT:
A deployable inlet for use with a center boost engine on a jet propelled aircraft having the capability of aerodynamically fairing the air inlet located in the leading edge of the vertical stabilizer at such times as the center boost engine is shut down and non-operative, thus minimizing drag. More particularly, an inlet construction for use with aircraft of the type commonly employing multiple main power plants and an auxiliary center boost engine of the type which is commonly used only: (i) during take-off; (ii) during air refueling operations; and/or (iii), under certain emergency operating conditions; and, wherein the air inlet for such center boost engine is located at the root leading edge of the aircraft's vertical stabilizer. The stabilizer's lower leading edge quarter chord panels define inlet doors for the air inlet, with such doors completely sealing the inlet and lying in the same general plane as the skin surface of the vertical stabilizer when such doors are in the closed position so as to define a smooth continuous airfoil stabilizer surface. In use, the inlet doors defined by the vertical stabilizer lower leading edge quarter chord panels are opened by pivoting outwardly to form the inlet's highlight and throat geometry; yet, when not in use, the inlet doors define a smooth continuation of the vertical stabilizer aerodynamic surfaces, thereby eliminating the need to dedicate additional structure and/or volumetric storage space for such doors.
