We are working on developing indigenous 100 N Microjet Gas turbine [MGT] engine for education and defense sector. The idea of manufacturing microjet engines in India revolves around supporting domestic engineering expertise and infrastructure to create compact, efficient propulsion system that can be used for educational purpose in universities and research institutions to train future engineers and researchers by providing Test Lab Setup. Moreover, this engines can be adapted for UAVs and drones, enhancing defense capabilities by providing reliable propulsion system attached to target UAVs or drones for testing missile accuracy and effectiveness. This will boost technological advancement within the country. Additionally if possible, in near future with Research and Development facilities, this MGTs with slight modification can be used with Sustainable Aviation Fuel for reducing carbon and NOx emission and increasing efficiency.
