UAV Turbojets & Turboprops
The Next Generation in Long Endurance Surveillance UAV’s
Brayton: US Air Force
A popular motive on the current military market for small development companies, such as Brayton, are UAV initiatives.
With rapid evolution in compact efficient engines, continued development of small unmanned engines is at a high demand. Over the past few years Brayton has worked with DOD, US Air Forces to help develop certain components in UAV engines ranging from 7kW to 12kW using speed alternators. In addition Brayton is developing a 90kW Turboprop assembly with gearbox.
Markets are not only throughout the military, but for higher-end cinematography and data acquisition for geological or meteorological research. These engines with their very small turbine components remain a great candidate for additive manufacturing technology.
