  • Cowling arrangement
    Patent number: 8052377
    Abstract: A gas turbine engine including a bypass duct defined by radially outer and inner walls, the radially inner wall defined by acoustic panels. The acoustic panels define the outer wall of a heated fire zone. In conventional engines an insulating blanket is attached to the panels, however, this is heavy and costly. Cooling film means are configured to pass bypass air through and over an internal surface of the panel.
    Type: Grant
    Filed: October 30, 2007
    Date of Patent: November 8, 2011
    Assignee: Rolls-Royce PLC.

  • Cooling arrangement for electronics
    Publication number: 20080110593
    Abstract: An aircraft electrical component cooling arrangement comprises at least one electrical component (40) housed in a body (38), for example an engine's electronic controller, characterised in that fuel is passed through the body (38) and directly over the component (40). Advantageously, this maintains a uniform temperature of the electronic components, protection against internal and external fire, ability to further miniaturise electrical components and/or combine units due to enhanced cooling effectiveness over convention air cooled systems.

  • Cowling Arrangement
    Publication number: 20080112796
    Abstract: A gas turbine engine (10) comprising a bypass duct (22) defined by radially outer and inner walls (27, 30), the radially inner wall (30) defined by acoustic panels (30). The acoustic panels (30) define the outer wall of a heated fire zone. In conventional engines an insulating blanket is attached to the panels, however, this is heavy and costly. The present invention comprises cooling film means (50) to pass bypass air through and over an internal surface (39) of the panel (30).
