J. C. Dunaway 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).

  • Rotational canted-joint missile control system
    Patent number: 6646242
    Abstract: The Rotational Canted-Joint Missile (RCJM) Control System utilizes a single or multiple body joints that rotate in planes that are not perpendicular to the missile body axis. The result is the deflection of a portion of the missile body for flight control purposes. The canted interface plane between any two adjacent movable sections of the missile body and a joint at the interface plane that allows one of the sections to be rotated by a pre-determined angle with respect to the other section comprise a rotational plane mechanism that offers an inclined bearing plane with a large mechanical advantage over typical “brute force” ball joint methods.
    Type: Grant
    Filed: February 25, 2002
    Date of Patent: November 11, 2003
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: Roger P. Berry, Daniel F. Lawless, Stephen C. Cayson, Lamar M. Auman, J. C. Dunaway, Mark D. Dixon, David A. Gibson

  • Gaseous secondary injection thrust vector control device
    Patent number: 4686824
    Abstract: Apparatus for modulating the thrust vector of a rocket motor by injecting t gas into the divergent section of the rocket nozzle and modulating injection of the hot gas by varying the flow from a solid propellant gas generator by controlling its flow rate with a vortex throttling valve arrangement.

  • Active control of solid propellant generators using throat modulation techniques and programmable compensation
    Patent number: H747
    Abstract: A system for controlling solid propellant gas generators including a microcessor which has inputs such as the sensed temperature of the gases in the solid propellant gas generator, the pressure within the solid propellant gas generator and/or pre-programmed input control signals to the microprocessor for causing the microprocessor to produce signals that are used to control a modulation valve which in turn controls a thrust nozzle device that controls exhaust gases from the solid propellant gas generator.
