  • Bleed airflow balancing control using simplified sensing
    Patent number: 8033118
    Abstract: A simplified air bleed balancing control system for a pair of aircraft gas turbine engines reduces the number of pressure transducers and differential pressure transducers. Advantages include lower weight, less expensive system, better total system MTBF (mean time before failure), acceptable differential pressure transducer drift identification and compensation by the digital controller, and fewer maintenance tasks.
    Type: Grant
    Filed: January 31, 2008
    Date of Patent: October 11, 2011
    Assignee: EMBRAER—Empresa Brasileira de Aeronautica S.A.
    Inventors: Oswaldo Barthel Monteiro, Vinicius Jorge Tin, Bernardo Campos da Silva Franco, Ricardo Jose Barbosa
