The aviation industry is witnessing a revolution that will see integration of more electricity to power vehicles. One factor leading this revolution stems from environmental constraints (in order to lower the emissions): studies into the electrification of aircraft propulsion revealed the potential of reducing carbon footprint by 50% between 2005 and 2050 – supporting ACARE goals. This step-change in technology / architectures will require new ways of collaborating among airframers, engine manufacturers and system suppliers – and addressing the regulatory framework and means of compliance for these new architectures. Hybrid/Electric Aircraft promise to be one of the enablers in realizing ACARE Flightpath 2050 goals.
