  • Publication number: 20180229853
    Abstract: An aircraft fuel tank inerting system includes an inlet, an oxygen absorption unit, and a vent to discharge oxygen from the system. The inlet may be configured to be in fluid communication with a ullage of a fuel tank. In embodiments, the oxygen absorption unit is in communication with the inlet and includes a chamber, a temperature reversible oxygen absorption medium within said chamber, and a temperature controller for selectively heating or cooling the medium. The reversible oxygen absorption medium may be a medium which absorbs oxygen by chemisorption.

  • Publication number: 20160236792
    Abstract: An on board inert gas generation system for use in an aircraft having a source of low pressure air includes a variable speed rotary positive displacement compressor with an inlet that receives a first portion of the low pressure air and an outlet in flow communication with an air separation module; a turbine that receives a second portion of the low pressure air to extract energy to drive the compressor; a heat exchanger in a flow path between the compressor and the air separation module, the heat exchanger including a heating pass and a cooling pass, such that compressed air from the compressor is passed along the cooling pass to reduce a temperature of the compressed air supplied to the air separation module; and a duct for supplying cool ram air to the heating pass of the heat exchanger. The compressor provides variable air flow to the air separation module.

  • Patent number: 9346555
    Abstract: An on board inert gas generation system receives cabin air, or air from another relatively low pressure source, passing a portion thereof through an energy recovery turbine to ambient to extract power which is used to provide all, or part of, the energy required to drive a positive displacement compressor to compress another portion of cabin air to increase the pressure thereof to be suitable for supply to an air separation module.

  • Patent number: 8471182
    Abstract: The present invention relates to a system and method for automated or “robotic” application of hardfacing to the surface of a steel-toothed cutter of a standard earth-boring rock bit or a hybrid-type rock bit. In particular, the system incorporates a grounded adapter plate and chuck mounted to a robotic arm for grasping and manipulating a rock bit cutter, particularly a hybrid rock bit cutter, beneath an electrical or photonic energy welding source, such as a plasma arc welding torch manipulated by a positioner. In this configuration, the torch is positioned substantially vertically and oscillated along a horizontal axis as the cutter is manipulated relative along a target path for the distribution of hardfacing. Moving the cutter beneath the torch allows more areas of more teeth to be overlayed, and allows superior placement for operational feedback, such as automatic positioning and parameter correction.

  • Patent number: 7971828
    Abstract: An inerting system for an aircraft fuel tank (10) uses an air separation device (12) to produce a supply of nitrogen-enriched air to replenish the fuel tank on consumption of fuel and to maintain the pressure difference across the walls of the tank (10) below design limits. The air separation device (12) provides substantially the whole of the mass of the gas required and so there is substantially no inward venting. This provides a substantially homogenous nitrogen content in the air in the tank (10).

  • Publication number: 20080066581
    Abstract: A shank configuration for rotary drill bits, is disclosed for positioning of the shank in relation to the bit body. A tapered surface or feature of the shank may be configured and sized to matingly engage a complementarily shaped surface or feature of the drill bit body and thereby become centered or positioned in relation thereto. A deformable element may be disposed between the shank and bit body. Also, the shank may comprise a material having a carbon equivalent of less than about 0.35%. A multi-pass weld procedure may be employed to affix the shank and bit body to one another wherein welds may be formed so that one weld originates at a circumferential position that differs from the origination circumferential position of its immediately preceding weld by at least about 90°. Further, a stress state may be developed within the multi-pass weld. A method of manufacture is also disclosed.
