NACELLE INLET ASSEMBLY WITH ACOUSTIC PANEL - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240017845 titled 'NACELLE INLET ASSEMBLY WITH ACOUSTIC PANEL

Simplified Explanation

The abstract describes an inlet assembly for a nacelle, which includes an inlet cowl and a plenum back wall of a fluid ice protection system (FIPS). The inlet cowl extends from the front end to the rear end and has a lipskin defining the leading edge. An acoustic panel is coupled to the lipskin at an interface, with a seam defined between them. The plenum back wall is affixed to the interior surface of the lipskin, creating a plenum between the interior surface and the front surface of the plenum back wall. The plenum receives an anti-ice liquid, and the plenum back wall is positioned in front of the seam along the length of the inlet cowl.

  • The invention is an inlet assembly for a nacelle with a fluid ice protection system (FIPS).
  • The inlet cowl extends from the front end to the rear end and has a lipskin defining the leading edge.
  • An acoustic panel is coupled to the inner side of the inlet cowl at an interface, with a seam defined between them.
  • The plenum back wall is affixed to the interior surface of the lipskin, creating a plenum between them.
  • The plenum receives an anti-ice liquid, and the plenum back wall is positioned in front of the seam along the length of the inlet cowl.

Potential Applications

  • Aircraft engine nacelles
  • Aerospace industry
  • Anti-ice systems

Problems Solved

  • Prevention of ice formation on the inlet cowl of a nacelle
  • Protection of the acoustic panel from ice accumulation
  • Efficient distribution of anti-ice liquid

Benefits

  • Improved ice protection for aircraft engines
  • Enhanced performance and safety during icy conditions
  • Reduced maintenance and downtime due to ice-related issues


Original Abstract Submitted

an inlet assembly for a nacelle includes an inlet cowl and a plenum back wall of a fluid ice protection system (fips). the inlet cowl extends a length from a front end of the inlet cowl to a rear end of the inlet cowl. the inlet cowl includes a lipskin that defines a leading edge of the inlet cowl at the front end, and an acoustic panel coupled to the lipskin at an interface along an inner side of the inlet cowl. a seam is defined between the acoustic panel and the lipskin. the plenum back wall is affixed to an interior surface of the lipskin to define a plenum between the interior surface and a front surface of the plenum back wall. the plenum receives an anti-ice liquid. the plenum back wall is disposed in front of the seam along the length of the inlet cowl.
