Title: Innovations by Lawrence T Halstead
Introduction
Lawrence T Halstead is a notable inventor based in Hartland, MI (US). He has made significant contributions to the field of turbine engine technology, holding a total of 2 patents. His work focuses on enhancing the performance and efficiency of gas turbine engines through innovative designs.
Latest Patents
One of Halstead's latest patents is the "Filament wound drum compressor rotor." This invention features a drum compressor rotor designed for use in gas turbine engines. It comprises a plurality of high strength, low density filaments that are covered with a high-temperature adhesive resin and tightly wound around the hub between rows of fan blades. This design allows for an increase in the maximum compressor rotor operating speed, thereby enhancing the potential performance of the turbine engine. The filament windings are significantly lighter and less expensive than conventional welded metal support disks.
Another significant patent is the "Ceramic-matrix composite nozzle assembly for a turbine engine." This nozzle assembly includes an annular ceramic-matrix composite hub with integral radially outwardly extending vanes, along with a pair of annular ceramic-matrix composite shrouds. These components interlock to secure the radially outermost ends of the vanes, providing peripheral support. The quasi-isotropic laminate structure of both the hub and shroud materials generates uniform physical properties, which enhances the structural integrity of the nozzle assembly during engine operation.
