ALEXANDRIA, Va., Sept. 17 -- United States Patent no. 12,416,437, issued on Sept. 16, was assigned to UNITED AIRLINES INC. (Chicago).
"Air cycle machine failure alert system" was invented by Justin Sindewald (Chicago) and Shuang Ling (Chicago).
According to the abstract* released by the U.S. Patent & Trademark Office: "Disclosed herein is a method for failure prediction in an Air Cycle Machine (ACM). The method includes calculating a change in energy of an ACM airflow passing from an inlet of the ACM compressor to an outlet of the ACM compressor. The method may also include calculating a kinetic energy of the ACM compressor based on calculating the work of the ACM compressor on the ACM airflow as the ACM airflow passes through the ACM com...
