James D. Blevins 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).

  • Propulsion system with integrated rocket accelerator
    Patent number: 7849670
    Abstract: The present invention relates to a propulsion system for a vehicle. The propulsion system has an airframe integrated hydrocarbon fueled airbreathing engine, such as a ramjet or a scramjet. The propulsion system further has at least one rocket positioned so as to use the aft body contour of the vehicle directly for flow expansion. In a preferred embodiment, a plurality of rockets are arrayed across the width of the engine nozzle.
    Type: Grant
    Filed: April 15, 2003
    Date of Patent: December 14, 2010
    Assignee: United Technologies Corporation
    Inventors: Stephen A. Beckel, James D. Blevins, Thomas Verdi

  • Strut cavity pilot and fuel injector assembly
    Publication number: 20080196414
    Abstract: A ramjet engine has an inlet, an outlet, and a gas flowpath from the inlet to the outlet. A pilot recess is along the flowpath. A plurality of struts extend within the flowpath. Each strut has first and second side surfaces extending between leading and trailing ends the trailing end sweeping away from the recess in a downstream direction across from the pilot recess. Each strut has first and second distributed fuel outlets positioned to discharge fuel from the first and second side surfaces respectively.

  • Gas turbine engine augmentor
    Patent number: 4765136
    Abstract: The pilot section of a flameholder of an augmentor for a gas turbine engine is modified to improve the ignition and stability characteristics by judiciously locating aperture(s) or slot(s) in the pilot section wherein their orientation is critical so as to create a vortical flow field.
