Patent ID: 7618006

Claim:
A ram air inlet comprising: an inlet lip portion; an inlet sidewall portion positioned downstream of the inlet lip portion; an inlet housing portion spaced apart from the inlet lip portion, and an inlet door movably positioned at least approximately adjacent to the inlet lip portion to form a variable inlet opening therebetween, the inlet door including: a first surface portion positioned upstream of the inlet lip portion, wherein the first surface portion includes a forward edge region pivotally attached to the inlet housing portion, and wherein the forward edge region is spaced apart from the inlet lip portion by a first distance; and a second surface portion fixed at an angle relative to the first surface portion and positioned downstream of the inlet lip portion opposite the inlet sidewall portion, wherein the second surface portion includes an aft edge region spaced apart from the forward edge region by a second distance that is greater than the first distance, wherein movement of the inlet door in a first direction reduces the inlet opening to decrease a flow of ram air through the inlet opening, and wherein movement of the inlet door in a second direction enlarges the inlet opening to increase the flow of ram air through the inlet opening.
