Example. This expansion of gases forces the engine's pistons to pump and powers the car. MSU's engine has no pistons. It uses the combustion of air and fuel to build up pressure within the engine, generating a shockwave that blasts hot gas exhaust into the blades of the engine's rotors causing them to turn, which generates electricity.

      Dr Ron Smith joined the British helicopter company Westland in , working in Research Aerodynamics, remotely piloted helicopters, before becoming Head of Future Projects. He had a strong influence on the design of the NH90, and was involved in the assessment of the Apache for Britain. He also explored a variety of exotic future technologies for Westland.   Future Propulsion Systems and Energy Sources in Sustainable Aviation is a comprehensive reference that offers a review of the science and engineering principles that underpin the concepts of propulsion systems and energy sources in sustainable air transportation.
