FLUID PRESSURE BASED ICING DETECTION FOR A TURBINE ENGINE
First Claim
1. A method for detecting icing in an aircraft turbine engine, the method comprising:
- measuring air pressure at a port located near a rotating component of the aircraft turbine engine to obtain air pressure measurements; and
warning of a potential icing condition when at least one characteristic of the air pressure measurements over time is indicative of the presence of ice covering the port.

Abstract
An icing detection subsystem for an aircraft turbine engine is presented. The icing detection subsystem includes a plurality of air pressure sampling ports formed within structure that surrounds a rotating component of the aircraft turbine engine. The subsystem also includes a pressure sensor arrangement coupled to the plurality of air pressure sampling ports to obtain air pressure measurements for the plurality of air pressure sampling ports. A processing module is coupled to the pressure sensor arrangement to analyze the air pressure measurements over time during operation of the aircraft turbine engine, and to generate an alert when at least one characteristic of the air pressure measurements over time is indicative of the presence of ice in the aircraft turbine engine.

9. A turbine engine comprising:
-
a rotating component; structure associated with the rotating component, wherein the rotating component rotates within the structure when the turbine engine is operating; an air pressure sampling port formed within the structure and exposed to airspace defined within the structure; a pressure sensor fluidly coupled to the air pressure sampling port to obtain air pressure measurements for the air pressure sampling port; and a processing module coupled to the pressure sensor to analyze the air pressure measurements over time and to determine when at least one characteristic of the air pressure measurements over time is indicative of the presence of ice at the air pressure sampling port. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
