  • Controllable diffuser for an air intake of an aircraft
    Patent number: 4641678
    Abstract: A diffuser for an air intake of an aircraft has an inlet and an outlet, both with variable cross-sectional flow areas. At least one wall section of a diffuser defining flow channel is movable by one or separate lever linkage systems for varying the inlet and outlet cross-sectional flow areas. A control circuit, preferably a closed loop control circuit responsive to a control program, makes sure that optimal flow cross-sectional areas are maintained at the inlet and outlet of the diffuser to optimize the operation of the diffuser.
