Compressor scrolls for auxiliary power units

摘要

A compressor scroll is provided for redirecting an airflow from a compressor. The compressor scroll (150) includes a spiral-shaped body (252); a radial inlet (250) formed in the body (252) for receiving the airflow from the compressor (124) as inlet airflow (262); and an outlet (254) formed in the body (252) such that inlet airflow (262) flows through the body (252) and exits the outlet (254) as outlet airflow (264), with at least a portion of the outlet airflow (264) crossing at least a portion of the inlet airflow (262).
