Abstract
An air inlet control inset in the skin or outer wall surface of an aircraft or the like. The control device has an open position in which it is able to capture ram air flowing over the wall surface and which at the same time defines an open flow area through which lower pressure ambient air can be inducted when ram air is unavailable. The air inlet control includes a shutter opening into ram air flow, and an actuating mechanism therefor. In one disclosed form of the invention, the shutter is aerodynamically biased to reduce actuating forces required to close the shutter against ram air pressure.
