Current Research Projects
Based on the Prometheus TEG technology, a novel contribution of our proposed NAPEC project will be the integration of a low cost modular TEG to power the fluid based actuation system of the EPSRC funded Cranfield University DEMON UAV. The Demon flying demonstrator is powered by a single AMT TITAN HP ES gas turbine engine, has a wing span of 2.53m, an estimated flying weight of ~90kg and speed range varies from 38 to 60 m/s. The Demon was tested in wind tunnels and as models before the full-scale flight trials took place.
The aircraft successfully demonstrated flapless flight when, for a planned portion of the test-flight, the conventional flap control system was turned off and the Demon flew and maneuvered using the new technology. The elimination or reduction in size of hinged flight control surfaces on an aircraft offers the possibility of reducing aircraft signature and reducing maintenance requirements and hence there is strong interest in developing means by which conventional flight controls can be replaced by controls that operate without altering the external geometry of the aircraft.
Prometheus is designed to integrate to existing infrastructures and take advantage of heat generation, especially heat waste. This improves the efficiency of energy generation.
Normally, the generation of electricity is only 42% efficient with over 50% energy loss in terms of the fuel input.
Prometheus can significantly increase the efficiency of this generation by utilising the temperature creation of the process, utilising the heat waste.
