A radical tilt engine design may simplify eVTOL system designs. Coriolis g Corps’ new approach as flight tested in their Vogi 1 model decouples the
potential environmental benefits of hybrid electric regional turboprop aircraft in terms of fuel consumption.
Published in the CEAS Aeronautical Journal , Volume 9, Issue 1, and written by lithium–air batteries as an energy source in combination with conventional fuel. It outlines a validated design and analysis framework extending it with sizing and analysis modules for hybrid electric propulsion system components.
The paper introduces a modified Bréguet range equation (above) suitable for hybrid electric aircraft. The results quantify the limits in range and performance for this type of aircraft as a function of battery technology level.
It suggests a typical design for 70 passengers with a design range of 1528 km, based on batteries with a specific energy of 1000 Wh/kg, providing 34% of the shaft power throughout the mission, would yield an emissions reduction of 28%.
