摘要:
A computer model of a gas turbine is analyzed using finite element analyses to determine the height of support jacks underneath the casing of the gas turbine. The computer model defines the gas turbine casing as an array of data points. Each data point includes information regarding the spatial location of the point and the mass (or weight) of the gas turbine with respect to that point. By applying finite element analysis, the load due to gravity and resulting deformation at each point on the gas turbine can be predicted. Jacks supporting the gas turbine are also simulated in the model to compensate for the casing deformation due to gravity. Results using the proposed iterative algorithm indicate the correct jack heights to minimize casing distortion.

This invention discloses a system and method for measuring and monitoring three-dimensional shaped objects with projections of computer models of the objects. The computer models of the three-dimensional shaped objects are in the form of grid patterns. An image of the computer model of grid patterns is simultaneously projected from a dual projection system in two directions onto a real world instance of the object. Any variation between the computer model and the real world instance of the object is highlighted directly on the object by interference patterns of the two projections on the real world instance. The variation is quantified by counting the number of interference patterns on the real world instance of the object.

A computerized process to generate ply patterns for manufacturing industrial parts by stacking and molding a large number of plies is based on solid modeling. The outermost shell of the part is unfolded to a planar pattern using a surface development procedure. The part is decomposed based on the ply thickness; the shell with the ply thickness is removed from the solid model once the surface is unfolded. A set of ply patterns are formed by repeating the unfolding process until no more volume remains. More accurate patterns are produced in less time, especially plies for complexly shaped composite parts such as aircraft engine components.

摘要:
A Handy Base Station (HBS) which is capable of connecting through a base portion into a power socket (e.g., lamp socket). The HBS may have a plurality of functional modules capable of being detachably mounted in a housing. One of the functional modules may be a light emitter such as a light emitting diode (LED). Another rmodule may be a communication module which may communicate using a wire line or wirelessly using standard wireless communication protocols. Further disclosed is a combination unit which has the HBS located on a pole such as a utility pole with a landing pad for an unmanned aerial vehicle (UAV) to allow the UAV a recharging location between deliveries and to allow the HBS to guide the UAV on its flight.

Installation of a flexible cured in place liner by inverting the liner utilizing an inversion sleeve assembly with an installation apparatus having at least one selectively operable rigid gland. The sleeve assembly includes a sleeve portion of an absorbable material secured in an apparatus with an inversion boot fitted at the distal end with an inlet port for inversion and/or curing fluid. The sleeve assembly and apparatus are particularly well suited for inverting with air and curing the liner with steam introduced through a perforated lay flat hose using an apparatus with two glands. The installation sleeve is the same dimension as the liner to be installed and is reusable thereby substantially reducing the set up time to install using the dual gland apparatus. Preferably, the flexible sleeve is a length of dry cured in place liner inverted on to itself to expose two impregnable surfaces. The sleeve may have a built in fluid inlet port for use with a dual gland apparatus.

A resin impregnated cured in place liner having an everted outer impermeable coating is provided. A roll of a continuous length of resin impregnable material is formed into a tube. An impermeable film or wrapping is formed into a tube about a tubular former, sealed and continuously everted about the inner tubular member travelling in an opposite direction so that the everted wrapping envelopes the inner tubular member. Alternatively, the inner tubular member may be passed into a stuffer tube having an impermeable tube thereon that is everted onto the moving tubular member to encapsulate the inner tubular member. The inner tubular member may be passed through an open resin impregnation tank to impregnate the impregnable material prior to everting the outer layer thereon. The inner tubular member may have an inner layer of impermeable material bonded thereto. It may be formed into a tube with the impermeable layer on the outside and continuously everted to place the impermeable layer on the inside of the tube.
