| 20090101759 | PANEL WITH IMPACT PROTECTION MEMBRANE - An aircraft leading edge panel having an outer aerodynamic surface; and an inner surface carrying the elastomeric impact protection membrane. The membrane comprises a woven or knitted fabric which is impregnated with an elastomeric material. The membrane and the panel may be bonded by an adhesive or co-cured to bond the membrane to the panel. The membrane provides impact protection to the panel by de-bonding from the face of the panel and absorbing at least part of the energy of an object impacting the panel. | 04-23-2009 |
| 20090184208 | AERODYNAMIC SEALING MEMBER FOR AIRCRAFT - A sealing member for forming a seal in an aircraft, the sealing member comprising: a sealing material; and a stiffening element which provides structural support to the sealing material and comprises a material with a glass transition temperature below +50° C. The stiffening element is relatively flexible when the aircraft is at low altitude (high temperature) but becomes relatively stiff (increasing resistance to seal flutter) when the aircraft is at cruise altitude (low temperature). | 07-23-2009 |
| 20090184477 | BLADE SEAL - A blade seal comprising: a base; a tip; a first part formed from an elastomeric material which extends continuously from the base to the tip; and a second part formed from an elastomeric material mixed with conductive filler which extends continuously from the base to the tip. The blade seal is manufactured by compressing the first and second parts together; and curing one or both of the parts as they are compressed together. | 07-23-2009 |
| 20100200700 | TANKS FOR CONTANING A FLUID WITHIN A CHAMBER - A tank for containing a fluid, such as fuel, oil or gas within a chamber. The walls of the chamber are partially defined by a rigid structure having an opening; and partially defined by an elastomeric diaphragm which is attached around its periphery to the rigid structure and covers the opening in the rigid structure. An attachment frame engages the diaphragm and the rigid structure, and extends around the periphery of the diaphragm. The attachment frame has a first portion which engages the diaphragm, and a second portion which is positioned outside an outer edge of the diaphragm and attached to the rigid structure. | 08-12-2010 |
| 20100221064 | FASTENER JOINT WITH SEALING GASKET - A joint comprising: a first component having a face and a bore defined by a bore wall; a second component; a fastener joining the first component to the second component, the fastener comprising a head and a shaft protruding from the head; and a polysulphide gasket comprising a ring which is compressed between the head of the fastener and the face of the first component; and a collar between the shaft of the fastener and the bore wall. | 09-02-2010 |
| 20100226061 | BONDING LEAD - A joint on an aircraft, a bonding lead for use in such a joint, and a method of manufacturing such a joint. The bonding lead comprises an elongate conductive core with a pair of end faces at the extremities of its length. The conductive core is encapsulated along at least a majority of its length and at both end faces in a barrier layer typically formed from an elastomer. The lead is encapsulated along its length in the barrier layer apart from at a first contact region towards a first end of the bonding lead and a second contact region towards a second end of the bonding lead. A first electrical connector passes through a first hole in the barrier layer to engage the first contact region of the conductive core and provide an electrical connection between the conductive core and the first component; and a second electrical connector passes through a second hole in the barrier layer to engage the second contact region of the conductive core and provide an electrical connection between the conductive core and the second component. | 09-09-2010 |
| 20100226062 | AIRCRAFT JOINT AND BONDING LEAD - A joint on an aircraft, the joint comprising: a first component; a second component; and a bonding lead which provides an electrical pathway between the first and second components. The bonding lead comprises a conductive core and a sheath which covers a substantial length of the core and has a lower electrical conductivity than the core. The path of least electrical resistance between the first component and the core of the bonding lead comprises the sheath, typically with an electrical resistance between 50 kΩ and 50 MΩ. By making the electrical resistance of the core much smaller than that of the sheath, the total resistance of the bonding lead remains substantially the same regardless of its length. | 09-09-2010 |
| 20100226063 | AIRCRAFT JOINT AND BONDING LEAD - A joint on an aircraft, the joint comprising: a first component; a second component joined to the first component; and a bonding lead which forms an electrical connection between the components with a resistance between 100 kΩ and 10 MΩ. Surprisingly, it has been found that a bonding lead with a relatively high resistance can be used without seriously compromising the static discharge performance of the bonding lead, and that the resulting comparatively low flow of current reduces the risk of sparking in the event of an lightning strike. Bonding leads may be provided as a kit of parts in which at least two of the bonding leads have different lengths and the longer lead is formed from a material having a higher bulk conductivity than the shorter lead. Thus the bonding leads can be made with approximately similar resistances regardless of their lengths. | 09-09-2010 |
| 20100242996 | AIRCRAFT COMPONENT WITH AERODYNAMIC SURFACE COATING - An aircraft component with an aerodynamic surface coating comprising a resilient foam with an array of open cells infused with a cleaning material such as a gel, paste or liquid. This prevents contaminants such as insects from adhering to the aircraft component. The resilient foam stores at least part of the impact energy of the contaminant, the cleaning material is released from the deformed foam so that the cleaning material at least partially coats the contaminant, and the foam springs back to eject the coated contaminant from the aircraft component. | 09-30-2010 |
| 20100243826 | LINE ROUTING CLIP - A routing clip for securing a line to a structure comprising: a base for attaching the clip to a structure; and a clamp comprising: a first flexible strap which extends from the base and has one or more projections extending from its side; and a second flexible strap which extends from the base and has a passageway for receiving the first flexible strap and a locking surface which is arranged to engage one of the projections on the first flexible strap to prevent the first flexible strap from being withdrawn from the passageway. At least part of the clip is made from an elastomeric material. | 09-30-2010 |
| 20100258674 | TRACK CONTAINER - An aircraft wing assembly comprising: a spar; a fuel tank; a track container which is attached to the spar and extends into the fuel tank; a track which extends through the spar and into the track container; and a high-lift device, such as a slat or flap, carried by the track. The track container comprises a stiffening element encased in an elastomeric sheath. The track container is manufactured by placing a stiffening element and elastomeric material together in a mould; and compressing and heating them to cure and shape the elastomeric material. | 10-14-2010 |
| 20100258686 | CABLE RACEWAY - A cable raceway comprising: a base; a pair of side walls extending from the base to define the edges of a cable channel; three or more legs extending from the base; and a flange at a distal end of each leg for attaching the leg to a support structure. The base, side walls, legs and flanges are formed from an elastomeric material. The base contains reinforcement which extends along the length of the raceway and is embedded within the elastomeric material. | 10-14-2010 |
| 20110147523 | PIPE COUPLING DEVICE FOR AIRCRAFT WING - An aircraft wing comprising first and second fuel pipe segments which are coupled together with a pipe coupling device comprising a corrugated tube formed from an elastomer filled with conductive material. The pipe coupling device is particularly useful for connecting together fuel pipe segments in an aircraft wing as it removes the need to attach bonding leads between fuel pipe segments to dissipate lightning currents and static. | 06-23-2011 |
