| 20100193114 | Apparatus and Method for Forming Fibre Reinforced Composite Structures - A method and apparatus for forming a fibre reinforced composite structure comprising at least two components, a hard base tool presenting a first tool face, a second tooling element presenting a second tool face to locate the second component against the first component. Components are of a dry fibrous form and are to be injected with a liquid resin. A flexible bagging blanket forms with the tools a sealed enclosure into which the resin is injected to form the structure by resin transfer infusion. To maintain the relative dispositions of the components without the need for elaborate mandrel plates, control rods are inserted at least partially through the two components to act as fasteners and to maintain the relative disposition of the components during resin injection. After injection the assembly is cured and the control rods may remain in situ or be removed from the structure. | 08-05-2010 |
| 20090301056 | AIRCRAFT ENGINE THRUST REVERSER - A power unit for providing propulsive thrust includes an efflux duct defining a first fluid flow path along which gaseous fluid travels for discharge from a first fluid exit opening to provide propulsive thrust. The power unit also has a thrust reversing structure which, when in a deployed position, redirects the flow of gaseous fluid along a second fluid flow path to discharge from a second fluid exit opening to provide reverse thrust. The thrust reversing structure includes longitudinally translating cowl portions, which are moveable from a stowed position to the deployed position where the translating cowl portions block a major portion of the first fluid exit opening to cause gaseous fluid to efflux from the second fluid exit opening. The translating cowl portions move in a generally longitudinal direction towards the deployed position along a path which is inclined to the power unit axis. | 12-10-2009 |
| 20080213618 | Anodising Aluminum Alloy - An anodic oxide film is formed on an aluminium or aluminium alloy work piece by forming an anodic oxide film on the work piece by AC electrolysis followed by subjecting the work piece to DC electrolysis. The AC anodizing step may be conducted at a voltage of 5 to 30V for 30 seconds to 10 minutes and the DC anodizing step may be conducted at a voltage of 5 to 30V for a period of 1 to 20 minutes. The anodic oxide coating is suitable for adhesive bonding of aluminium alloy work pieces. | 09-04-2008 |
