Operating Principles. The principle used by a gas turbine engine as it provides force to move an airplane is based on Newton''s law of momentum. This law states that for every action there is an equal and opposite reaction; therefore, if the engine accelerates a mass of air (action), it applies a force on the aircraft (reaction).
The advantages of electric drives and conventional combustion engines can be combined in series hybrid-electric aircraft through appropriate aircraft design. As a consequence, energy-efficient aircraft with sufficient range can be realised in general aviation. The sizing of the energy storage system has a significant impact on the range, …

In 2015, the global aircraft fleet consumed 276 million tonnes of jet fuel—7% of global oil products 1. However, reliance on oil products comes at an environmental cost. Aircraft CO 2 emissions ...
Because renewable hydrogen draws on renewable energy sources, it is considered as "cleaner" and more sustainable than comparable energy-storage systems. It is for this key reason that aeronautics engineers—including those at Airbus—are taking a closer look at hydrogen as a potential technology pathway for zero-emission aircraft.
In solar-powered aircraft, an energy storage system is needed to meet the intense power demand during takeoff, landing, and some maneuvers and to provide …
Hybrid-electric aircraft are supported by energy sources such as hydrogen, solar, and supercapacitor in addition to batteries. Depending on the purpose and structure of the aircraft, the appropriate energy sources are used at different hybridization rates. Download conference paper PDF.
