  • Propellant transfer system and method for resupply of fluid propellant to on-orbit spacecraft
    Patent number: 9260206
    Abstract: Herein is disclosed a propellant transfer system and method for refueling on-orbit spacecraft. The system and method are configured to allow for resupply of spacecraft configured to be fueled by either a bipropellant (oxidizer and fuel) or a monopropellant (typically hydrazine). The system and method are particularly suited for resupply of satellites not originally prepared for refueling as well but the system may also be used for as satellites specifically designed for refueling.
    Type: Grant
    Filed: November 26, 2014
    Date of Patent: February 16, 2016
    Assignee: MACDONALD, DETTWILER AND ASSOCIATES INC.
    Inventors: Andrew Allen, John Lymer, Kerry Spring, Rangaswamy Ravindran
