US Classification:

415108, 415115, 4151821

Abstract:

A method for assembling a gas turbine engine includes coupling a rotor assembly including a plurality of rotor blades about a rotatable main shaft of the gas turbine engine. The main shaft is aligned in an axial direction of the gas turbine engine. A shroud assembly is coupled to the gas turbine engine. The shroud assembly includes a plurality of shroud segments circumferentially coupled about the rotor assembly such that a shroud spacing gap is formed in the axial direction between adjacent shroud segments. A cooling fluid source is coupled to each shroud segment such that cooling fluid is channeled through each shroud segment into a corresponding shroud spacing gap to facilitate positive purge flow through the shroud spacing gap.

Abstract:

A solar collector having two axis control and cogeneration capabilities is provided. The solar collector may have a primary collecting mirror, a second reflecting mirror, and a solar collector positioned adjacent to the primary mirror. The collector may realize both direct solar to electricity production via photovoltaic cells or the like, as well as heat collection generated by the collected solar energy. The collected heat may be transferred to a fluid which may be transferred for productive uses such as electricity production, heating, cooling, and the like.
