摘要:
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.

摘要:
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. The diffusing medium is created, in a predetermined ratio, by mixing a water-soluble polymeric material that forms a transparent solution by being dissolved in water, a light curable hydrophilic monomer having hydrophilicity and a high dispersion in water, a photoinitiator for inducing a polymerization by interacting with the light curable hydrophilic monomer, and a solvent.

摘要:
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).
摘要:
There is disclosed an anti-dazzling and electrostatic charge-preventive transparent coating material comprised of at least two kinds of conductive metallic compounds dissolved in an organic solvent and concentrated, the concentrate being added with water and catalyst to form a transparent solution containing fine particulates, ethyl silicate dissolved in another organic solvent, said transparent solution and the ethyl silicate solution being mixed together to cause hydration and polycondensation, thereby leading to the growth of particulate solid ingredient.

摘要:
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.
