  • MULTIPLE SCROLL AXIAL TURBINE
    Publication number: 20140165559
    Abstract: A turbocharger including a turbine wheel having a hub-to-tip ratio of no more than 60% and blades with a high turning angle, a turbine housing forming a pair of inwardly spiraling primary-scroll passageways that significantly converge to produce highly accelerated airflow into the turbine at high circumferential angles, and a two-sided parallel compressor. The compressor and turbine each produce substantially no axial force, allowing the use of minimal axial thrust bearings.
    Type: Application
    Filed: November 21, 2013
    Publication date: June 19, 2014
    Applicant: HONEYWELL INTERNATIONAL INC.
