  • Compressor surge prevention digital system
    Patent number: 9200572
    Abstract: Methods and devices for anticipating a surge in a gas turbine engine. Controlled pressure signal(s) may be compared with reference pressure signal(s), each of the controlled pressure signal(s) and reference pressure signal(s) having an associated time value. If the controlled pressure signal(s) are less than the reference pressure signal(s), a controlled pressure curve may be fitted through a predetermined number of points based on the controlled pressure value(s) and associated time value(s). A reference pressure curve may be fitted through the predetermined number of points based on the reference pressure value(s) and associated time value(s). A time to compressor surge may be estimated based on an intersection of the controlled pressure curve and the reference pressure curve.

  • Lubrication system for aircraft engine
    Patent number: 8312969
    Abstract: A lubrication system for an aircraft engine includes a lubrication fluid tank and a fluid passage communicating with the tank to define an entry of the passage inside the tank. The entry is positioned in a location submerged in the lubrication fluid for delivery of the lubrication fluid under a pressure differential, from the tank to the lubrication system regardless of the tank or aircraft attitude.
