  • Variable section nozzle for a turbo-jet engine and an aircraft comprising such equipment
    Patent number: 4577814
    Abstract: The invention relates to a variable area nozzle for a turbo-jet engine. This nozzle comprises a convergent portion, formed by a fixed semi-shell (2) and a semi-shell (3) pivotal about a diametral axis (4a-4b); the fluid-tightness of the convergent portion is ensured by a substantially semi-circular seal (6) and by two longitudinal seals (7a, 7b). The nozzle can be used for example with an engine comprising a partial re-heat system of moderate output.

  • Pressure drop regulating device
    Patent number: 4546606
    Abstract: The control device comprises at least one control ring to which one end of n elbow lever is articulated. The vane pivot of alternating vanes is fixed at the intersection of the arms of the elbow levers. The other end of each elbow lever is connected by a rod to the end of a straight lever, the other end of which is fixed to the pivot of an adjacent vane. The circumferential movement of the ring causes the pivots of the adjacent vanes to pivot in opposite directions. Two other embodiments have two rings.

  • Fuel distribution device
    Patent number: 4280324
    Abstract: The invention concerns a fuel distribution device in a high velocity gase flow. The device consists of two coaxial, toric injection manifolds placed in close proximity with respect to each other, pierced by small diameter uniformly distributed orifices and arranged to introduce fuel into the flow. The orifices in the manifold located downstream with respect to the direction of the flow of gases, are arranged on the face turned upstream of the manifold, in a circular row coaxial with it.It is the object of the invention to reduce the drag induced in the flow by the devices presently in use, while improving the distribution of the fuel; it finds particularly advantageous applications in the afterburner ducts of gas turbine engines.

  • Device for igniting fuel injected into a rapidly flowing gaseous medium
    Patent number: 4125998
    Abstract: An auxiliary chamber or ignition "prechamber" for afterburners of aeronautical turbine engines draws in, through a perforated plate, a carbureted mixture produced by fuel projected against an anvil by an injection manifold, and the injection manifold also issues a jet of fuel into a tube which discharges into the chamber downstream of a spark plug. The produced flame is guided into a flame stabilizer.
