The Council of Scientific and Industrial Research-National Aerospace Laboratories (CSIR-NAL) has unveiled three indigenous micro and small gas turbine engines designated as NJ-05, NJ-50, and NJ-100 at the CSIR Headquarters in New Delhi.
These engines, developed for deployment in defence Unmanned Aerial Vehicles (UAVs) and missile systems, feature thrust capacities of 5 kg (NJ-05), 50 kg (NJ-50), and 100 kg (NJ-100) to meet various operational needs. It is to be noted that these engines operate on the ‘Brayton cycle’, which is a thermodynamic cycle describing the workings of a constant-pressure heat engine.
