Electric Propulsion
Bye Energy is developing a practical, efficient, light-weight electric propulsion system as an alternative to traditional "avgas" powered internal combustion engines currently utilized by light general aviation aircraft. This clean electric propulsion system will provide the aviation community with an economical, more efficient, zero emission "green" propulsion option. The continued improvements in lithium-ion battery and separator technology, electric motors and lightweight aircraft design are key elements of this system. Additional benefits to this configuration include less routine maintenance and a longer service life than existing internal combustion engines.
History:
The core design of internal combustion engines on general aviation aircraft is based on technology developed 100 years ago. Although significant advances have been made to improve its performance and efficiency, the technology has generally advanced to the limits of its capabilities. These engines rely on a high-octane blend of fuel derived from petroleum-based crude oil. In addition to demonstrated price volatility, there are significant concerns over future availability. The need to explore and develop an alternative form of propulsion for general aviation is paramount.
Moving Forward:
Bye Energy's research on alternative propulsion systems has led to the conclusion that electro-chemical energy stored in battery units combined with a highly efficient electric motor is the most adaptable solution for aviation utility. Battery technology, in terms of energy density, weight, safety, cycle life, efficiency and cost, has advanced considerably over the past 10 years, due in large part to accelerated hybrid-electric research and development conducted for the automobile industry. This technology has now matured enough to provide adequate energy to meet the requirements of a typical internal combustion powered aircraft.
