Mohamed M. Ragab has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8196869
    Abstract: A cryogenic propellant depot and sunshield are provided for operation in earth orbit to fuel or refuel other space vehicles. The sunshield is deployed to effectively mitigate solar radiation emanating from the earth and the sun thereby providing a long term storage solution for cryogenic fluids prone to boil-off. The depot has supporting subsystems to include station keeping equipment and communication equipment so that the depot can be independently controlled. Inflatable booms are used to deploy the sunshield in a desired pattern around the depot.
    Type: Grant

  • Patent number: 5322248
    Abstract: An arrangement for controlling the flight of a launch vehicle and a coupled payload, such a spaceplane, from launch to the separation of the payload from the vehicle. The launch vehicle is provided with controllable gimballed rocket engines and optionally with aerodynamic control surfaces, that are controlled by flight control systems. The payload having controlled flight surfaces has control systems that cooperate with those flight control systems carried by the launch vehicle to jointly control the coupled launch vehicle and coupled payload during coupled flight. The cooperating flight control systems provide open and closed loop control systems that react to winds measured prior to launch and atmospheric disturbances as indicated by on-board sensors during flight. The payload is mounted on the launch vehicle at a cant angle relative to the longitudinal axis of the launch vehicle to optimize its lift to the coupled launch vehicle and payload.
