Patent number: 10066923Abstract: An ice thickness measurement sensor 100 is provided to measure the thickness of ice extending from a circuit. The ice thickness measurement sensor comprises at least one capacitive sensor 150. The capacitance of the sensor 150 depends on the thickness of ice covering the sensor, because the presence of the ice changes the permittivity. The ice thickness measurement sensor may be used in a fluid pipe, for example to measure the thickness of ice extending from the inner surface of the pipe.Type: GrantFiled: February 19, 2015Date of Patent: September 4, 2018Assignee: ROLLS-ROYCE plcInventors: Jeung Sang Go, Man Yeong Ha, Changmin Son, June Kee Min

Patent number: 7817337Abstract: The present invention generally relates to a laminated image panel and a fabrication method thereof for projecting images projected from an image optical engine, on a screen by reflecting and/or transmitting the images. The laminated image panel in accordance with the present invention comprises front elements, rear elements disposed in opposition to the front elements, sealants for forming a predetermined cell by mutually bonding opposed rim parts of the front elements and the rear elements and for sealing the front and rear elements by separating the front elements from the rear elements at certain intervals, and a diffusing medium injected into the cell and uniformly diffusing the projection images in transparent and/or semitransparent state.Type: GrantFiled: January 6, 2006Date of Patent: October 19, 2010Inventor: Changmin Son

Patent number: 7717668Abstract: A gas turbine engine simulator comprising a simulator rotor disc which has substantially the same maximum external dimensions as a rotor disc and is manufactured from a material which has a density of less than 220 kg/m3. The simulator rotor disc is manufactured from a foamed plastic material with a closed cell structure. The simulator rotor disc is provided with a cavity in flow communication with a source of simulator coolant fluid, at least one flow outlet, at least one heater unit and at least one thermocouple mounted within said cavity for the measurement of simulator coolant fluid temperature within said cavity.Type: GrantFiled: October 19, 2006Date of Patent: May 18, 2010Assignee: Rolls-Royce plcInventors: Changmin Son, Peter Ireland, Steven Thorpe, Terence Jones

Patent number: 7207776Abstract: A cooling arrangement comprises a support (20) for a plurality of blades (22). The support (20) comprises a plurality of blade mounting members (28) provided between adjacent blades (22). The blades (22) are mounted upon the blade mounting members (28). The cooling arrangement defines a pathway (36) for a cooling fluid. The cooling arrangement further includes a fluid directing formation (40, 44, 44A) to direct the cooling fluid across the blade mounting member (28).Type: GrantFiled: December 21, 2004Date of Patent: April 24, 2007Assignee: Rolls-Royce plcInventors: Roderick M Townes, Changmin Son, Colin Young

Patent number: 6688110Abstract: Where gas turbine engine structure eg combustion equipment, is to be air impingement cooled, the surface which receives the air jets is so shaped as to produce boundary layer separation zones 34, 38 and 44 in the cooling air, as it spreads across the surface. Mixing of the boundary layer with the remainder of the air flow results, followed by the re-establishment of the boundary layer. The new boundary layer is cooler than the original layer and so provides more effective cooling.Type: GrantFiled: November 22, 2002Date of Patent: February 10, 2004Assignee: Rolls-Royce plcInventors: Geoffrey M. Dailey, Changmin Son
