By Air Marshal Anil Chopra (Retd) The civil aerospace industry is primarily being influenced by environmental issues and cost of operations. The key areas of attention are propulsion and autonomous systems. Top engine-makers are unveiling new technologies to cut CO2 emissions and yet boost the performance of aircraft engines. Aircraft engines need to produce more power while consuming less fuel, produce less noise and reduce emission levels. These performance parameters can be achieved by enhancing the efficiency of combustion engines and simultaneously exploring

electric and hybrid propulsion systems. Considering that large number of drones and Urban Air Mobility (UAM) systems are beginning to fly over populated areas, the aero-acoustics of these engines will also be a design focus. Benefits of research and technology in propulsion will shorten engine development cycle, reduce engine weight, increase engine performance, reduce engine fuel consumption, enhance reliability, reduce emissions and noise, increase component life and reduce maintenance requirements.
