The invention relates to engine air intakes for aerospace vehicles in which a variable geometry ramp system is employed for matching air intake flow to propulsion engine demand. To alleviate the induced high pressure loads on the ramps and the ramp actuators arising from the air intake flow a reacting pressure is applied to the opposite face of the ramps. The ramp assembly in addition to defining the required air intake duct geometry further defines the adjacent boundary of an enclosure which is pressurized by ram air and vented as required as a function...
A variable air intake arrangement for an aircraft propulsion engine, said air intake arrangement comprising: an air intake duct, variable geometry ramp means mounted within said air intake duct and movable to selected positions across said air intake duct for controlling the amount of air passing therethrough to match propulsion engine demand, actuator means for moving said ramp means and for reacting induced intake air pressure loads on said ramp means, an air intake duct opening defined by a forward fixed ramp and an intake lip, variable geometry ramp ...
