| 5860276 | Ducted fan gas turbine engine mounting A ducted fan gas turbine engine is mountable on an aircraft structure via a pylon which includes a yoke. The yoke straddles the compressor module of the engine and is connected thereto at points diametrically opposite each other, thus obviating thrust lin... | 01/19/1999 |
| 5860787 | Rotor blade axial retention assembly A bladed rotor has blades fitted in grooves around its rim. The blades are prevented from making significant movement lengthways of their grooves by abutment members which are so formed as to enable fitting and removal without the use of special tooling.... | 01/19/1999 |
| 5860316 | Capacitance probe A proximity sensing apparatus comprising a capacitor and means for detecting the change in capacitance of the capacitor. The capacitor comprises two capacitive elements that are insulated from each other and are relatively movable. With at least one of th... | 01/19/1999 |
| 5860275 | Method of combining ducted fan gas turbine engine modules and aircraft structure In a ducted fan gas turbine engine the fan module is connected rigidly to aircraft structure and flexibly to the core gas generator via flanged annular diaphragms (62,66) thus obviating the exertion of bending loads on the core gas generator casing when t... | 01/19/1999 |
| 5836739 | Gas turbine engine A gas turbine engine comprises turbine and compressor elements on a rotary shaft. The shaft is rotably mounted on preloaded axial thrust bearings. As it rotates in use the turbine and compressor elements create an axial thrust load on the bearings. Accord... | 11/17/1998 |
| 5833244 | Gas turbine engine sealing arrangement In a sealing arrangement between two discs of a gas turbine engine a split sealing arrangement comprising a pair of sealing formations each made up of a plurality of sealing segments is provided. Each of the segments has a root accommodated in serrations ... | 11/10/1998 |
| 5797449 | Heat exchanger An annular heat exchanger suitable for a gas turbine engine comprises a first continuous sheet of material arranged in a spiral and a second continuous sheet of material arranged in a spiral. A first axially extending passage is defined between the first ... | 08/25/1998 |
| 5780146 | Abradable composition, a method of manufacturing an abradable composition and a gas turbine engine having an abradable seal An abradable seal comprises a plurality of hollow aluminosilicate spheres in a matrix of aluminium phosphate. The matrix of aluminium phosphate also has an aluminosilicate filler. The hollow aluminosilicate spheres have a diameter in the range of 400 to 1... | 07/14/1998 |
| 5576418 | Resorbable biocompatible copolymers and their use The invention relates to the use of copolymers of racemic lactide and &3xb5;-caprolactone, δ-valerolactone, gamma-decalactone or ଲ-hydroxybutyric acid, prepared by the reaction of the monomers in the molar ratio of lactide to reaction partner of ap... | 11/19/1996 |
