ABSTRACT:
An inlet system for an inlet in a flow field includes an inlet recess housing having an interior with forward and rear end walls, a base wall, and an opening formed in an upper surface thereof. An intake duct is formed in a rear end wall of the inlet recess. An inlet door has a first end pivotally connected to a forward wall and a trailing edge directed to the rear end wall of the inlet housing such that the inlet door selectively closes the opening of the inlet housing. An overlap member can extend from the rear end wall of the inlet recess to a predetermined distance adjacent a trailing edge of the door. A deflector is provided having an end deflecting portion in contact with the trailing edge of the door over at least a portion of the inlet door's pivoting path. Side deflecting portions project from the end deflecting portion toward the front wall of the inlet housing. The deflector controls pressure recovery of flow field at a fully open position of the door until the trailing edge of the door clears the end deflecting portion of the deflector.
