Abstract: A high strength T-joint for inflatable tubular is formed by forming a butt joint between the end of a first two tubular member and the side wall of a second tubular member. The opening in the side wall of the second tubular member is sized to match the end of the transverse support member so that a sealing flange can be applied to the inner surface of the joint to provide an airtight seal. A reinforcing flange comprising a disk-shaped piece of fabric having a center opening, is then bonded over the opening in the second tubular member. The center opening in the reinforcing flange is substantially smaller than the opening in the side rail member. Therefore the reinforcing flange substantially reduces the size of the discontinuity in the side wall of side rail member, thereby substantially increasing the circumferential (“hoop”) load capacity of the side wall of the side rail member and substantially increasing the rupture pressure of the joint.

Abstract: A method and a device for producing a sufficient quantity of a fire suppressing gaseous product to substantially suppress a fire. The device has a first stage gas source containing a pyrotechnic gas generating material and a second stage gas source in fluid communication at a first location with an outlet of the first stage gas source and, at a second location, with an outlet for dispersing gas. The second stage gas source contains at least one liquified gas or supercritical carbon dioxide, where the first stage gas source is capable of providing a sufficient quantity of gas at a sufficiently high temperature to vaporize at least a portion of the liquified gas or supercritical carbon dioxide in the second stage gas source, thereby producing a fire suppressing gaseous output, which exits the device through the outlet for dispersing gas, in an amount sufficient to at least partially suppress a fire.

Abstract: A combustor dome for use in a combustor has an igniter mounted in a central bore. Moving outward from the bore is a concentric pilot fuel passageway. Concentric about the pilot fuel passageway is an air passageway. Lastly, concentric about the air passageway is a premix passageway. The outlets of the pilot fuel passageway, the air passageway, and the premix passageway are generally coplanar.
