A “small scale” turbo-jet turbo-shaft gas turbine design course

Aero-thermo-mechanical Design of Small Gas Turbine Systems for Unmanned-Aerial Vehicle (UAV) and Environmental Applications (AERSP 597/497-K) A three credit design course by: Dr. Cengiz Camci 153-E Hammond Building

Introduction to Small Scale Turbomachinery systems (2) Fluid Mechanics and Thermodynamics of Turbomachinery for Unmanned Aerial Vehicles (UAV) (4) Turbomachinery Component Design Centrifugal compressor design (emphasize reduced size and use of light materials) (6) A single stage axial flow turbine design (6) Mechanical aspects of shaft and rotor disk design (3) Design of a low cost and efficient combustor (6) Inlet, diffuser and nozzle design system (6) Gas Turbine Component Matching (3) Gas Turbine Health Monitoring and Control Mechanisms (3) Presentations and lab activities (6)

Why is this design course offered? Small gas turbine systems with a maximum diameter of less than 10 inches have a tremendous application potential in Aerospace and Mechanical engineering systems. In Aerospace engineering, Unmanned-Aerial Vehicles (UAV) using small gas turbine systems are designed and operated for reconnaissance&surveillance, battle damage assessment, targeting and communications relay.

UAV’s will also be highly effective in future Environmental Engineering applications for sensing chemical, nuclear and biological hazards. Collecting atmospheric/meteorological information using real time imaging and sensing devices is also possible by using UAV’s powered by small gas turbine systems. Successful implementation of small gas turbines in ground based applications is also likely in the next century. Hybrid electric car recharging its batteries using a miniature gas turbine is an excellent automotive concept helping to effectively reduce environmental pollutants released to the atmosphere.
