  • Turbojet engine thrust reverser with variable exhaust cross-section
    Patent number: 4922713
    Abstract: A trust reverser is disclosed for a turbofan-type turbojet engine having the capabilities of reversing the air passing through a cold flow air duct to provide a reverse thrust for the engine and also adjusting the cross-section of the cold flow air duct. This enables the cold flow air duct to be increased in cross section during periods of high thrust operation, a cowl defining the outer limits of the cold flow air duct has a stationary portion arranged generally, concentrically about the hot gas exhaust duct, and two movable portions, each of which are movable axially with respect to the stationary cowl. Locking systems are utilized to releasably lock a first movable cowl to the stationary cowl, and to releasably lock the second movable cowl to the first movable cowl.
