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.
