Abstract: An apparatus and method for retaining pressure vessel closures (14, 15) on a container is described which utilizes alignment slots (26) disposed about the container and closure, with a filament (28) wound about the container and closure for retaining the closure to the container. The fiber, which includes a curable polymer, assures that the closure is firmly retained on the pressure vessel. Utilizing a fiber for retaining the closure to the container avoids welding, impact fasteners or the use of threaded fasteners and thus significantly reduces the weight and complexity of the pressure vessel.

Abstract: A center post electrochemical cell stack is disclosed for generating a product gas such as oxygen gas from a supply fluid such as water. The invention could be used to generate oxygen on board a space or aircraft and includes: a frame having a base plate (14) and a wall (16) affixed to the base plate so that the wall and base plate define a cell chamber (18) for housing at least one electrochemical cell; and a T-cap having a top plate (24) and a centeer post (26) affixed to and projecting away from the top plate, wherein the top plate is secured to the wall of the frame to close the cell chamber and the center post passes through a central throughbore in an electrochemical cell within the chamber and is adjustably secured to the base plate of the frame. Consequently, the T-cap and frame cooperate to contain pressure generated by operation of the electrochemical cell. In a specific embodiment of the center post electrochemical cell stack, an exterior surface of the center post of the T-cap cooperates with a central throughbore vented electrochemical cell to define a high pressure manifold (34) for venting of the product gas out of the cell, and an interior surface (36) of the wall of the frame cooperates with the vented central throughbore cell to define a low pressure manifold (40) for transmission of the supply fluid into and out of the cell.

Abstract: A technique for controlling compressor stall and surge is disclosed. In a gas turbine engine, static pressure asymmetry is sensed at a plurality of locations along the circumference of the compressor inlet. Time rate of change of the mass flow in the compressor is also estimated using pressure measurements in the compressor. A signal processor uses these signals to modulate a compressor bleed valve responsive to the level of flow property asymmetry, the time rate of change of the annulus average flow to enhance operability of the compressor.

Abstract: A hybrid composite flexbeam (10) for a soft inplane bearingless main rotor assembly (100) has eight spanwise regions: a hub attachment region (12); a first tapered region (14); a second tapered region (16); an inboard transition region (18); a pitch region having a cruciform configuration (20); an outboard transition region (22); a tapered outboard transition region (24); and a main rotor blade, torque tube attachment region (26). The pitch region (20) is formed from unidirectional fiberglass plies, a 50/50 admixture of unidirectional fiberglass and graphite plies, and unidirectional graphite plies. Unidirectional fiberglass and graphite plies of varying lengths are interleaved in the second inboard tapered region (16). Fiberglass and graphite cross plies of varying lengths are interleaved in the first inboard tapered region (14). Fiberglass and graphite cross plies and unidirectional fiberglass plies of varying length are interleaved in the outboard tapered region (24). The distributed arrangement of ply endings cause kick loads (97) in the hybrid flexbeam (10) to be distributed across the ply buildups.
