Disclosed is a rotary disc balancing simulation mass for balancing a rotary disc configured to support a set of rotary components, wherein the rotary disc balancing simulation mass is configured to be attached to the rotary disc and configured to simulate the mass of two or more of the rotary components. Also disclosed are balancing simulation apparatus, and methods of balancing a rotary disc.

Balancing simulation mass, apparatus and associated methods

A system for applying a tensile load to a component includes a failsafe structure, a principal part of which is configured to act in compression during application of the load to the component, but which includes a mechanical fuse configured to act in tension during application of the load to the component. The mechanical fuse being configured to fracture upon the application of a predetermined tensile force thereto.

System and method for applying a tensile load to a component, having a mechanical fuse

A method for predicting initial unbalance in a component comprising one or more elements, the method comprising: defining a statistical distribution of a mass moment weight of each of the one or more elements; restricting the statistical distribution to a selected range; and calculating an initial unbalance of the component for the restricted distribution of the one or more elements.

Method for predicting initial unbalance in a component

A method of manufacturing a rotating component, the method comprising the providing a component comprising a first portion, which first portion defines a first cavity, characterised by; identifying a first inertial property of the first portion and/or the entire component, introducing material into the first cavity to achieve an adjusted inertial property of the first portion and hence a desired inertial property of the component. A rotating component including a first portion defining a first cavity, a second portion defining a second cavity, the second portion being circumferentially spaced from said first portion, the first cavity has a first material deposit therein, said material having predetermined inertial characteristics so as to adjust the centre of mass (Z) of the rotating component.

Bladed rotor balancing

Actuator, especially suited for an actuating mechanism for parabolic and other reflector dishes. The actuator comprises two co-axial cylinders ( ). A helical guideway ( ) is provided on the outer surface of the inner cylinder ( ) or the inner surface of the outer cylinder ( ), and a plurality of guide means are provided on the other of the outer surface of the inner cylinder ( ) or the inner surface of the outer cylinder ( ) to run in or along the helical guideway ( ). The actuator is elongated or contracted by relative rotational movement of the cylinders ( ).

Cylindrical actuator

Solar energy receiver having two or more regions for acceptance of solar radiation, and a means for splitting the solar radiation into two or more wavelength bands. A different band of radiation is incident upon each of the regions. At least one of the regions includes a means, such as a filter, to substantially prevent radiation having a wavelength longer than that incident on the region from leaving the region.

Solar energy receiver assembly

Collection of solar radiation and its conversion into electrical power

A method of producing a composite structure consists of winding a resin impregnated filament tow onto a former or formers having surfaces which correspond with a portion of the finished article, removing the fibre sheets from the former or formers, and placing them in a mould which corresponds in shape to that of the complete article, and pressing the fibre within the mould to consolidate the finished article.
