Patents by Inventor Duane L. Jensen

Duane L. Jensen 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: 5463957
    Abstract: A flexible, aerodynamic inflatable nose fairing for use in combination with flat nosed canister launched missiles having a wide circular cylindrical shape. The inflatable nose fairing is fabricated as a fiber-reinforced elastomeric membrane having a laminate construction which includes a silicone rubber inner or base layer as the gaseous pressure membrane or bladder, surrounded by two or more ply layers made up of resin-impregnated yarns. In a preferred embodiment, the silicone rubber bladder is applied to a generally conical shaped mandrel. The first ply layer is fabricated by hoop winding resin impregnated yarns on a constant diameter cylinder and then cutting to form gores. The gores are applied to the conical shaped mandrel such that the gore fibers are oriented in the axial direction of the conical shaped mandrel.

  • Patent number: 5464172
    Abstract: A flexible, aerodynamic inflatable nose fairing for use in combination with flat nosed canister-launched missiles having a wide, circular, cylindrical shape. The inflatable nose fairing is fabricated as a fiber-reinforced elastomeric membrane having a laminate construction which includes a silicone rubber inner or base layer as the gaseous pressure membrane or bladder, surrounded by two or more ply layers made up of resin-impregnated yarns. Also disclosed is a deployable mass assembly and sensor for providing improved missile control. The deployable mass assembly includes a telescoping actuator which is effective to provide stabilization control to the missile by shifting the center of gravity of the missile forwardly to compensate for a change in the center of pressure of the missile due to the change in length of the missile which occurs as the nose fairing is inflated into its deployed position.
