Aerospace Engineering Mechanical Engineering turbomachinery structural analysis gas turbine propulsion novel concept The Dual Compression Rotor (DCR) is a turbine engine componenttechnology which enables the novel turbine engine concept titled the RevolutionaryInnovative Turbine Engine (RITE). The DCR and RITE concept is an attempt toprovide significant improvements over the traditional turbine engine design. TheRITE concept, along with the DCR, represents a paradigm shift over the traditionalturbine engine design. The design of the DCR features two compressor stages, oneforward flow and one reversed flow, along with an outer turbine stage on a singlerotor. The RITE concept offers the potential to decrease specific fuel consumptionover the current state of the art, while maintaining thrust and decreasing turbineinlet temperature. The RITE concept will eliminate the need for cooling andimprove performance during operation away from the design point. The DCRdecreases engine axial length requirements, reducing weight, and features availableturbine cooling flow inboard on the rotor. This thesis focuses on the development ofa small scale demonstration of the DCR concept. An iterative design process wasperformed on the DCR until an aerodynamic design of the compressor and turbinestages aligned with the structural performance of available materials. Finiteelement analysis was performed on the DCR geometry for each iteration. Followingthe establishment of a preliminary design, additional design work was performed onstatic structures, dynamic face seals, bearings, and test fixtures. Lead time for thefabrication of the DCR and static structures prohibited the inclusion of experimentalresults; however, suggested testing procedures and conclusions based on the designbeing fabricated are included. 2013-05-23 English text University of Dayton / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=dayton1366644139 http://rave.ohiolink.edu/etdc/view?acc_num=dayton1366644139 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
